Aims: We conducted a prespecified subanalysis of the POEM trial to assess the association between sex and clinical outcomes following a short 1-month dual-antiplatelet-therapy (DAPT) period after percutaneous coronary intervention (PCI) with bioresorbable polymer everolimus-eluting stent (BP-EES) among patients at high bleeding risk (HBR)., Background: Shortening the DAPT period after PCI is an effective bleeding avoidance strategy with contemporary drug-eluting stents. Whether sex affects the risk of adverse events following PCI is still debated., Methods: Patients at HBR undergoing PCI with BP-EES were enrolled and treated with 1-month DAPT. If anticoagulation was needed, study participants received an oral anticoagulant (OAC) in addition to a P2Y 12 inhibitor for 1 month, followed by OAC only thereafter. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis at 12 months. We report sex-based outcomes of patients included in the POEM study., Results: We enrolled 129 (29.1%) women and 314 (70.9%) men. Women were older, with lower hemoglobin levels, and worse renal function. Accordingly, they had a trend for a greater number of HBR criteria fulfilled and a higher PARIS bleeding score. However, they were not at a significantly higher risk for the primary endpoint (men vs. women: 5.17% vs. 3.94%; HR 1.30; 95% CI: 0.48-3.54, p = 0.61), or any of the hemorrhagic and ischemic secondary endpoints., Conclusions: This prespecified subanalysis of the POEM trial suggests that 1-month DAPT following PCI with BP-EES may be a safe and effective therapeutic strategy for women at HBR., (© 2024 The Author(s).

Background: Previous studies have investigated a 1 to 6-month short dual antiplatelet therapy (S-DAPT) after percutaneous coronary intervention (PCI) with modern drug eluting-stents to reduce bleeding events., Objectives: To investigate cardiovascular outcomes in patients at high bleeding risk (HBR) according to the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria after PCI with the Synergy bioresorbable-polymer everolimus-eluting stents (EES)., Methods: We applied ARC-HBR criteria in the population of the prospective, single-arm, multicenter POEM (Performance of Bioresorbable Polymer-Coated Everolimus-Eluting Synergy Stent in Patients at HBR Undergoing Percutaneous Coronary Revascularization Followed by 1-Month Dual Antiplatelet Therapy) trial. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 12 months., Results: The original POEM cohort included 356 patients (80.4 %) fulfilling ARC-HBR criteria. Oral anticoagulant (OAC) usage and age ≥75 years were the most frequent major and minor ARC-HBR criteria, respectively. The ARC-HBR group was mainly represented by men (71.1 %), with 74.4 ± 9.3 years and a high burden of cardiovascular risk factors. DAPT was prescribed in 79.3 %, and single antiplatelet (SAPT) with OAC in 18.7 %. 12-month follow-up was completed in 96.2 %. The primary endpoint occurred in 5.2 % (95 % CI 3.29-8.10) of patients, whereas bleeding Academic Research Consortium type 3-5 occurred in 2.7 % (95 % CI, 1.39 %-5.05 %)., Conclusion: Previous results of the POEM trial showed positive outcomes regarding ischemic and bleeding events with an S-DAPT regimen after Synergy EES. These results are also confirmed in sub-group analysis when ARC-HBR criteria are applied., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Data deriving from patients who underwent TAVR between 2007 and 2017 in 13 Italian centers were prospectively collected. Patients were stratified in those with normal LVEF and reduced LVEF. The latter was further classified according to ischemic or nonischemic etiology. The primary end point was a composite of all-cause death and rehospitalizations; the secondary end points were the isolated composers of the primary end point and cardiac death. Overall, 2,626 patients were included in the analysis: 68.1% with normal LVEF and 31.9% with reduced LVEF. At 8 years, reduced LVEF was significantly associated with the primary end point (adjusted hazard ratio 1.17, 95% confidence interval 1.06 to 1.29). Consistent findings were evident for the composite end point. No differences in these trends were found at the 30-day landmark analyses. Compared with nonischemic etiology, ischemic reduced LVEF was associated with an increased risk of cardiac death (adjusted hazard ratio 1.43, 95% confidence interval 1.02 to 2.02). In conclusion, patients with reduced LVEF who underwent TAVR are exposed to a progressively increased risk of death and rehospitalizations, even at very long-term follow-up., Competing Interests: Declaration of competing interest CG, MA, and MDC received speaker fees from Medtronic; FB received consultant/proctor fees from Medtronic; MM received consultant fees from Abbott, Boston, Kardia and Medtronic; TP received lectures fees from Medtronic, Edwards and Abbott.

Although many studies highlighted the potential of COVID-19 to reshape existing models of wildlife management, empirical research on this topic has been scarce, particularly in Europe. We investigated the potential of COVID-19 pandemic to accelerate the ongoing decline in an aging population of recreational hunters in Italy. Namely, we modelled spatiotemporal trends between 2011 and 2021 in the number of recreational hunters in 50 Italian provinces with a varying incidence of COVID-19, and temporally delayed waves of infection. Compared to projections from 2011-2019 data, we detected a lower number of hunters who enrolled for the hunting season, both in 2020 (14 provinces) and in 2021 (15 provinces). The provinces with the highest incidence of COVID-19 in the Lombardy and Emilia-Romagna regions were also those experiencing the most marked decrease in hunting participation. Our findings revealed that a wildlife management system based on recreational hunting can be rapidly destabilized by epidemics and their associated public health measures, particularly when the average age of hunters is high, like in Italy. Considered the high incidence attained by COVID-19 in many European countries, where hunters are pivotal for the management of large ungulates and where they were already declining before the pandemic, our findings call for further large-scale research about the impact of COVID-19 on hunting participation., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Cerri et al.

Introduction: Recent studies have shown gender differences in cardiovascular outcomes after left atrial appendage closure (LAAC), highlighting different complication rates and adverse events, particularly in short-term assessments. As a result, there remains a significant knowledge gap on how these differences directly impact the efficacy and safety of LAAC procedures. The aim of this retrospective study was to investigate the clinical outcomes of LAAC in women and men using the Watchman FLX device., Methods: This retrospective, multicenter study analyzes gender-specific outcomes in 650 patients who underwent LAAC with the Watchman FLX device between March 2019 and May 2022, drawn from the ITALIAN-FLX registry., Results: The results show comparable rates of all-cause mortality, stroke, transient ischemic attack and major bleeding in men and women 12 months after the procedure. Notably, no significant gender differences were found for periprocedural complications., Conclusion: In conclusion, this study shows that LAAC with the Watchman FLX device has comparable clinical outcomes between genders at both short-term and long-term follow-up., Competing Interests: SB has been a consultant for Abbot and Boston Scientific Inc.

Second-generation Anticoagulant Rodenticides (ARs) can be critical for carnivores, due to their widespread use and impacts. However, although many studies explored the impacts of ARs on small and mesocarnivores, none assessed the extent to which they could contaminate large carnivores in anthropized landscapes. We filled this gap by exploring spatiotemporal trends in grey wolf (Canis lupus) exposure to ARs in central and northern Italy, by subjecting a large sample of dead wolves (n = 186) to the LC-MS/MS method. Most wolves (n = 115/186, 61.8 %) tested positive for ARs (1 compound, n = 36; 2 compounds, n = 47; 3 compounds, n = 16; 4 or more compounds, n = 16). Bromadiolone, brodifacoum and difenacoum, were the most common compounds, with brodifacoum and bromadiolone being the ARs that co-occurred the most (n = 61). Both the probability of testing positive for multiple ARs and the concentration of brodifacoum, and bromadiolone in the liver, systematically increased in wolves that were found at more anthropized sites. Moreover, wolves became more likely to test positive for ARs through time, particularly after 2020. Our results underline that rodent control, based on ARs, increases the risks of unintentional poisoning of non-target wildlife. However, this risk does not only involve small and mesocarnivores, but also large carnivores at the top of the food chain, such as wolves. Therefore, rodent control is adding one further conservation threat to endangered large carnivores in anthropized landscapes of Europe, whose severity could increase over time and be far higher than previously thought. Large-scale monitoring schemes for ARs in European large carnivores should be devised as soon as possible., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: The wild boar (Sus scrofa) and the Apennine wolf (Canis lupus italicus) are two wild species that have both increased their presence in the Italian territory, albeit in varying numbers. They can be occasionally found in peri-urban areas as well. Both of these species can serve as intermediate hosts for Toxoplasma gondii, as they can become infected either through the consumption of oocysts found in water, soil, or on vegetables, or through the ingestion of meat containing bradyzoites. Consequently, these animals can be regarded as key indicators of Toxoplasma presence in the wild or peri-urban environment. In our study, we examined a total of 174 wild boar meat juice and 128 wolf sera from Italy for the detection of T. gondii IgG using the indirect fluorescent antibody test (IFAT)., Results: The results showed that 40 (22.6%) of the wild boar meat juice and 34 (26.6%) of the wolf serum samples tested positive. Interestingly, there were no significant differences in seropositivity with respect to gender, age group, or the region of origin in both species., Conclusions: Overall the results indicate a moderate exposure in both the species under investigation, highlighting the spread of T. gondii in sylvatic and periurban environments. The prevalence of T. gondii in wild boar is consistent with findings from other studies conducted in Europe. Our study, with a considerably larger sample size compared to the available research in European context, provides valuable data on the seroprevalence of T. gondii in wolves., (© 2024.

Background: The only natural hosts of Pseudorabies virus (PRV) are members of the family Suidae (Sus scrofa scrofa). In mammals, the infection is usually fatal and typically causes serious neurologic disease. This study describes four Aujeszky's disease cases in free-ranging Italian wolves (Canis lupus italicus). In Italy, the wolf is a strictly protected species and is in demographic expansion., Case Presentation: Three wolves (Wolf A, B, and C) were found in a regional park in Northern Italy, and one (Wolf D) was found in Central Italy. Wolf A and D were alive at the time of the finding and exhibited a fatal infection with epileptic seizures and dyspnoea, dying after a few hours. Wolf B presented scratching lesions under the chin and a detachment of the right earlobe, whilst Wolf C was partially eaten. The wolves showed hepatic congestion, diffuse enteritis, moderate pericardial effusion, severe bilateral pneumonia, and diffuse hyperaemia in the brain. The diagnostic examinations included virological analyses and detection of toxic molecules able to cause serious neurological signs. All four wolves tested positive for pseudorabies virus (PrV). The analysed sequences were placed in Italian clade 1, which is divided into two subclades, "a" and "b". The sequences of Wolf A, B, and C were closely related to other Italian sequences in the subclade b, originally obtained from wild boars and hunting dogs. The sequence from Wolf D was located within the same clade and was closely related to the French hunting dog sequences belonging to group 4., Conclusion: Results showed the presence of PrV strains currently circulating in wild boars and free-ranging Italian wolves. The genetic characterisation of the PrV UL44 sequences from the four wolves confirmed the close relationship with the sequences from wild boars and hunting dogs. This fact supports a possible epidemiological link with the high PrV presence in wild boars and the possibility of infection in wolves through consumption of infected wild boar carcasses or indirect transmission. To the best of our knowledge, this study is the first detection of Pseudorabies virus in free-ranging Italian wolves in northern and central Italy., (© 2023. The Author(s).)

Background: Balloon post-dilation (BPD) is a widely adopted strategy to optimize acute results of TAVI, with a positive impact on both paravalvular leak and mean gradients. On the other hand, the inflation of the balloon inside prosthetic leaflets may damage them increasing the risk of structural valve deterioration (SVD). Furthermore, the impact of BPD on long-term clinical outcomes and valve hemodynamics is yet unknown., Aims: To evaluate the impact of BPD on valve durability and long-term clinical outcomes in patients undergoing self-expanding transcatheter valve implantation (TAVI)., Methods: Echocardiographic and clinical data from the ClinicalService (a nation-based data repository and medical care project) were analyzed. Patients were divided into two groups, those who underwent BPD after TAVI and those who did not. Coprimary endpoints were all-cause death and SVD. Cumulative incidence functions for SVD were estimated., Results: Among 1835 patients included in the study, 417 (22.7%) underwent BPD and 1418 (77.3%) did not undergo BPD. No statistically significant differences at 6-year follow-up were found between groups in terms of all-cause mortality (HR: 1.05, 95% CI: 0.9-1.22; p = 0.557) and SVD (2.1% vs. 1.4%, p = 0.381). In addition, BPD did not predispose to higher risk of cardiovascular death, myocardial infarction, valve thrombosis, and endocarditis at 6-year follow-up., Conclusions: BPD following TAVI with a self-expanding prosthesis does not seem to be associated with an increased risk of adverse clinical outcomes or SVD at 6-year follow-up., (© 2023 The Authors.

Limited data are available about the impact of permanent pacemaker (PPM) implantation on long-term survival in patients with a bicuspid aortic valve (BAV) and severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR). We aimed to evaluate the long-term clinical outcomes of patients with BAV with AS who underwent periprocedural PPM implantation after TAVR with a self-expandable prosthesis. Data from patients with BAV and severe AS who underwent TAVR between April 2009 and January 2022 and followed in the framework of the One Hospital ClinicalService-CoreValve Project were collected. Patients were categorized in 2 groups according to PPM implantation after TAVR ("PPM" group) or not ("no PPM" group). The coprimary end points were all-cause death and a composite of cardiac mortality, rehospitalization because of cardiac causes, stroke, and myocardial infarction. Overall, 106 patients were considered (74 in the "no PPM" group and 32 in the "PPM" group). No statistically significant difference was found between the groups in terms of follow-up and baseline characteristics. Patients in the PPM group were more likely to show baseline conduction abnormalities (p = 0.023). Patients in the PPM group were more often treated with older generation prosthesis than those in the no PPM group (28.1% vs 5.4%, respectively, p = 0.013). At 2 years of follow-up, all-cause death in the no PPM and PPM groups occurred in 20.0% and 10.0% of patients, respectively (hazard ratio 0.37, 95% confidence interval 0.08 to 1.67). Similarly, no difference was evident for the composite end point between the 2 groups (no PPM vs PPM: 8 [14.6%] vs 6 [19.3%], hazard ratio 1.67, 95% CI 0.58 to 4.81). In conclusion, patients with severe AS and BAV treated with TAVR complicated by PPM implantation are not exposed to an increased risk of major adverse events at 2 years of follow-up., Competing Interests: Declaration of Competing Interest Dr. Matteo Montorfano received consultant fees from Abbott, Boston, Kardia, and Medtronic.

Background: To provide a comprehensive analysis of the current literature comparing the outcomes of surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic stenosis (BAS), with particular attention to BAV morphology in patients undergoing TAVR., Methods: Following PRISMA guidelines, all relevant articles with no design restrictions from PubMed, CCTR (Cochrane Controlled Trials Register), and Google Scholar were screened for inclusion. Studies were included if they reported clinical endpoints for SAVR and TAVR or, in BAS treated with TAVR, for type 1 and non-type 1 morphology. Odds ratio and Cohen's D were considered as effect size measurements for qualitative and quantitative variables, respectively., Results: A total of eight studies comparing short-term outcomes between SAVR and TAVR and nine studies with outcomes data between type 1 and non-type 1 BAS treated with TAVR were considered for the final analysis. No statistically significant difference was found for what concerns the rates of death, stroke, and acute kidney injury between SAVR and TAVR. In comparison to patients undergoing SAVR, the incidence of PPI (permanent pacemaker implantation) was greater in the TAVR group (OR 0.35, 95% CI 0.15-0.79, p = 0.01), and the frequency of bleeding events was found to be higher among patients undergoing SAVR (OR 4.3, 95% CI 2.9-6.4, p < 0.001). The probabilities of 30-day mortality, stroke, and any bleeding were not significantly affected by bicuspid valve morphology in TAVR patients. PPI or development of new conduction anomalies was found to be more frequent in type 1 anatomies (OR 0.46, 95% CI 0.30-0.70, p <0.001). Mildly lower post-procedural transprothesic gradients were found in patients with type 1 morphology., Conclusions: In BAS patients, TAVR has comparable short-term outcomes rates with SAVR, but higher PPI rates and lower incidence of bleeding events. In patients undergoing TAVR, type 1 BAS is associated with lower postoperative transvalvular gradients but higher PPI rates and conduction abnormalities.

There is a paucity of data regarding the safety of a 1-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients at high bleeding risk (HBR) presenting with acute coronary syndromes (ACS). We aimed to compare the clinical outcomes of patients at HBR with chronic coronary syndrome (CCS) or ACS treated with PCI using bioresorbable polymer everolimus-eluting stent (BP-EES) followed by 1-month DAPT. Patients at HBR who underwent PCI with BP-EES were prospectively enrolled in 10 Italian centers. All patients were treated with 1-month DAPT. In case of need for anticoagulation, patients received an oral anticoagulant in addition to a P2Y12 inhibitor for 1 month, followed by oral anticoagulation only after that. The primary end point was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis at 12 months. Overall, 263 patients (59.4%) with CCS and 180 patients (40.6%) with ACS were enrolled. No significant difference was evident between patients with CCS and ACS for the primary end point (4.3% vs 5.6%, respectively, p = 0.497) and for each isolated component. The risk for Bleeding Academic Research Consortium (BARC) type 1 to 5 or type 3 to 5 bleedings was also similar between patients with CCS and ACS (4.3% vs 5.2%, p = 0.677, and 1.6% vs 2.9%, p = 0.351, respectively). In conclusion, among HBR patients with ACS who underwent PCI with BP-EES, a 1-month DAPT strategy is associated with a similar risk of ischemic and bleeding events compared with those with CCS., Competing Interests: Declaration of Competing Interest Dr. Testa has received consulting fees, personal and institutional honoraria, and has served on the advisory board participation from Abbott, Medtronic, Biotronik, Boston Scientific Corporation, Terumo Lifesciences, Meril, Cardionovum, Concept Medical.

Background: Myocardial ischemia (INOCA) and acute myocardial infarction with non-obstructive coronary artery disease (MINOCA) represent emerging entities in the landscape of interventional cardiology. These conditions have heterogeneous pathophysiological mechanisms and clinical presentations, complex diagnostics, and high prognostic significance., Methods: This survey was carried out jointly by the GISE Young Committee with the support of the SICI-GISE Society and the ICOT group with the aim of evaluating the implementation of diagnostic-therapeutic pathways in cases of suspected/confirmed INOCA and MINOCA diseases. A web-based questionnaire based on 22 questions was distributed to SICI-GISE and ICOT members., Results: The survey was distributed to 1550 physicians with 104 (7%) responses. The majority of participants included interventional cardiologists (70%), in two-thirds of cases working in centers with high volume of procedures (>1000 coronary angiographies/year), who estimated a <10% annual rate of INOCA and MINOCA cases in their case load. Approximately 25% of the participants stated that they do not have the option of performing any investigation for the evaluation of patients with suspected INOCA, and less than 50% make use of advanced invasive testing for the diagnosis of MINOCA, including physiology and intravascular imaging tests. It also turns out that about 50% of respondents reported the present and future absence of dedicated diagnostic-therapeutic pathways. Even with a high perception of the clinical relevance of these diseases, about 40% of the respondents rely on clinical experience or do not deal with their management, also reporting a low prevalence of dedicated follow-up care (20% of cases followed at dedicated outpatient clinics). Factors predominantly limiting the prevalence of appropriate diagnostic and treatment pathways included the cost of materials, lack of training and expertise of practitioners, and of solid data on the long-term clinical efficacy of treatments., Conclusions: Currently, the proper management of INOCA and MINOCA disease is widely advocated but poorly implemented in clinical practice. To reverse the trend and solve the remaining controversies, it is necessary to enhance awareness, produce robust scientific data, and implement dedicated pathways for patients.

West Nile (WNV) and Usutu (USUV) viruses are two mosquito-borne viruses belonging to the family Flaviviridae and genus Flavivirus. The natural transmission cycle of WNV and USUV involves mosquitoes and birds, while mammals are thought to be accidental hosts. The goal of this study was to report-in the context of "off-season monitoring" and passive surveillance-the detection of WNV and USUV RNA in wild birds. To this end, we analyzed biological samples of wild birds in Northern Italy, from October to May, hence outside of the regional monitoring period (June-September). The virological investigations for the detection of USUV and WNV RNA were performed using real-time PCR on frozen samples of the brain, myocardium, kidney, and spleen. In a total sample of 164 wild birds belonging to 27 different species, sequences of both viruses were detected: four birds (2.44%) were positive for WNV and five (3.05%) for USUV. Off-season infections of WNV and especially USUV are still widely discussed and only a few studies have been published to date. To the best of our knowledge, this study is the first report on the detection of USUV RNA until December 22nd. Although further studies are required, our results confirm the viral circulation out-of-season of Flavivirus in wild birds, suggesting reconsidering the epidemiological monitoring period based on each individual climate zone and taking into consideration global warming which will play an important role in the epidemiology of vector-borne diseases.

Transcatheter aortic valve replacement (TAVR) is an established therapy for severe, symptomatic aortic valve stenosis even in patients with impaired left ventricular systolic function. However, there is uncertainty on the clinical effectiveness of the currently available TAVR devices in patients with reduced left ventricular ejection fraction (LVEF). The LOSTAVI (Low Systolic function and Transcatheter Aortic Valve Implantation) registry is a retrospective observational study using baseline, procedural, discharge, and long-term follow-up details. A total of 3 groups of interest were distinguished: extremely reduced LVEF (<25%), severely reduced LVEF (25% to 30%), and reduced LVEF (31% to 35%). Unadjusted and adjusted analyses were carried out for in-hospital and follow-up outcomes. A total of 923 patients were included from 12 centers, with 146 patients (16%) with LVEF <25%, 425 (46%) with LVEF 25% to 30%, and 352 (38%) with LVEF 31% to 35%. Several baseline and procedural features were different across groups, including age, risk, functional class, and prevalence of bicuspid disease (all p <0.05). In-hospital mortality was similar in the 3 groups (7 [4.8%], 18 [4.2%], and 7 [2.0%], respectively, p = 0.661), but major adverse events were more common in those with extremely reduced and severely reduced LVEF (19 [13%], 53 [13%], and 25 [7.1%], respectively, p = 0.024). The 12-month follow-up confirmed the significant detrimental impact of reduced LVEF on both death (21 [14%], 49 [12%], and 25 [7.1%], respectively, p = 0.024) and major adverse events (37 [25%], 89 [21%], and 53 [15%], respectively, p = 0.016). The adjusted analysis confirmed the significant prognostic role of LVEF on both outcomes, whereas TAVR device type was not associated with death or major adverse events (all p >0.05). In conclusion, TAVR yields favorable early and 1-year results in patients with reduced LVEF, including those with extremely depressed systolic dysfunction. However, reduced LVEF still represents a major adverse prognostic factor for both short- and mid-term outcomes., Competing Interests: Declaration of Competing Interest Dr. Biondi-Zoccai has consulted for Amarin, Balmed, Cardionovum, Crannmedical, Endocore Lab, Eukon, Innovheart, Guidotti, Meditrial, MicroPort, Opsens Medical, Terumo, and Translumina.

Background: The relationship between high postprocedural mean gradient (ppMG) and clinical events following mitral valve transcatheter edge-to-edge repair (MV-TEER) in patients with degenerative mitral regurgitation (DMR) is still debated., Aim: The purpose of this study was to evaluate the effect of elevated ppMG after MV-TEER on clinical events in patients with DMR at 1-year follow-up., Methods: The study included 371 patients with DMR treated with MV-TEER enrolled in the "Multi-center Italian Society of Interventional Cardiology (GISE) registry of trans-catheter treatment of mitral valve regurgitation" (GIOTTO) registry. Patients were stratified in tertiles according to ppMG. Primary endpoint was a composite of all-cause death and hospitalization due to heart failure at 1-year follow-up., Results: Patients were stratified as follows: 187 with a ppMG ≤ 3 mmHg, 77 with a ppMG > 3/=4 mmHg, and 107 with a ppMG > 4 mmHg. Clinical follow-up was available in all subjects. At multivariate analysis, neither a ppMG > 4 mmHg nor a ppMG ≥ 5 mmHg were independently associated with the outcome. Notably, the risk of elevated residual MR (rMR > 2+) was significantly higher in patients belonging to the highest tertile of ppMG (p = 0.009). The association of ppMG > 4 mmHg and rMR ≥ 2+ was strongly and independently associated with adverse events (hazard ratio: 1.98; 95% confidence interval: [1.10-3.58])., Conclusions: In a real-world cohort of patients suffering DMR and treated with MV-TEER, isolated ppMG was not associated with the outcome at 1-year follow-up. A high proportion of patients showed both elevated ppMG and rMR and their combination appeared to be a strong predictor of adverse events., (© 2023 Wiley Periodicals LLC.)

The gray wolf (Canis lupus) expanded its distribution in Europe over the last few decades. To better understand the extent to which wolves could re-occupy their historical range, it is important to test if anthropization can affect their fitness-related traits. After having accounted for ecologically relevant confounders, we assessed how anthropization influenced i) the growth of wolves during their first year of age (n = 53), ii) sexual dimorphism between male and female adult wolves (n = 121), in a sample of individuals that had been found dead in Italy between 1999 and 2021. Wolves in anthropized areas have a smaller overall variation in their body mass, during their first year of age. Because they already have slightly higher body weight at 3-5 months, possibly due to the availability of human-derived food sources. The difference in the body weight of adult females and males slightly increases with anthropization. However, this happens because of an increase in the body mass of males only, possibly due to sex-specific differences in dispersal and/or to "dispersal phenotypes". Anthropization in Italy does not seem to have any clear, nor large, effect on the body mass of wolves. As body mass is in turn linked to important processes, like survival and reproduction, our findings indicates that wolves could potentially re-occupy most of their historical range in Europe, as anthropized landscapes do not seem to constrain such of an important life-history trait. Wolf management could therefore be needed across vast spatial scales and in anthropized areas prone to social conflicts., Competing Interests: The authors declare no competing interest, regarding the study., (Copyright: © 2023 Cerri et al.

In recent years, the growth of wild ungulates has increased the focus on their health monitoring. In particular, the health status of wild boars is relevant for the economic impact on the pig industry. The Emilia-Romagna region activated a wildlife monitoring plan to better evaluate the health status of the wild boar population. Between 2011 and 2021, samples of found dead and hunted wild boar have been examined for trichinellosis, tuberculosis, brucellosis, african swine fever, classical swine fever, Aujeszky's disease, swine vesicular disease, and swine influenza A. Trichinella britovi was identified in 0.001% of the examined wild boars; neither M. bovis nor M. tuberculosis were found in M. tuberculosis complex positive samples; 2.3% were positive for Brucella suis ; 29.4% of the sera were positive for Aujeszky's disease virus; and 0.9% of the samples were positive for swine influenza A virus. With an uncertain population estimate, the number of animals tested, the number of positives, and the sampling method do not allow us to make many inferences but suggest the need to implement and strengthen the existing surveillance activity, as it seems to be the only viable alternative for safeguarding animal and human health.

Background: Over the past decades, the improvements in the diagnostic power and availability of non-invasive cardiac imaging techniques have led to a decline of right heart catheterization (RHC) performance. However, RHC remains the gold standard for diagnosing pulmonary hypertension and an essential tool for the evaluation of patient candidacy to heart transplantation., Methods: This survey was carried out jointly by the Young Committee of GISE, with the support of the SICI-GISE Society, and the ICOT group, with the aim of evaluating how the interventional cardiology community perform RHC. A web-based questionnaire based on 20 questions was distributed to SICI-GISE members., Results: The survey was distributed to 1550 physicians with 174 (11%) responses. Most centers perform few procedures per year (<10 RHC/year) and a dedicated cardiologist is usually lacking. Patients were frequently admitted as ordinary hospitalization regimen and the most frequent indication for RHC was the hemodynamic assessment of pulmonary hypertension, followed by diagnostics of valvular diseases and advanced heart failure/heart transplantation. Indeed, the majority of participants (86%) are involved in transcatheter procedures for structural heart disease. The average time taken to perform the RHC was approximately 30-60 min. The femoral access (60%) was the most frequently used, usually by an echo-guided approach. Two-thirds of participants discontinued oral anticoagulant therapy before RHC. Only 27% of centers assess wedge position from an integrated analysis. Furthermore, the edge pressure is detected in the end-diastolic cardiac phase in half cases and in the end-expiratory phase in only 31%. The most commonly used method for cardiac output calculation was the indirect Fick method (58%)., Conclusions: Guidance on the best practice for performing RHC is currently lacking. A more precise standardization of this demanding procedure is warranted.

In the last decades, advances in percutaneous coronary intervention (PCI) strategies have significantly reduced the risk of procedural complications and in-hospital mortality of patients with acute coronary syndromes (ACS), thus increasing the population of stable post-ACS patients. This novel epidemiological scenario emphasizes the importance of implementing secondary preventive and follow-up strategies. The follow-up of patients after ACS or elective PCI should be based on common pathways and on the close collaboration between hospital cardiologists and primary care physicians. However, the follow-up strategies of these patients are still poorly standardized. This SICI-GISE/SICOA consensus document was conceived as a proposal for the long-term management of post-ACS or post-PCI patients based on their individual residual risk of cardiovascular adverse events. We defined five patient risk classes and five follow-up strategies including medical visits and examinations according to a specific time schedule. We also provided a short guidance for the selection of the appropriate imaging technique for the assessment of left ventricular ejection fraction and of non-invasive anatomical or functional tests for the detection of obstructive coronary artery disease. Physical and pharmacological stress echocardiography was identified as the first-line imaging technique in most of cases, while cardiovascular magnetic resonance should be preferred when an accurate evaluation of left ventricular ejection fraction is needed. The standardization of the follow-up pathways of patients with a history of ACS or elective PCI, shared between hospital doctors and primary care physicians, could result in a more cost-effective use of resources and potentially improve patient's long-term outcome.

Background: Data on left main (LM) percutaneous coronary interventions (PCI) have mostly been obtained in studies using drug-eluting stent (DES) platforms without dedicated large-vessel devices and with limited expansion capability., Aims: Our study aimed to investigate the safety and efficacy of LM PCI with the latest-generation Resolute Onyx DES., Methods: ROLEX (Revascularization Of LEft main with resolute onyX) is a prospective, multicentre study (ClinicalTrials.gov: NCT03316833) enrolling patients with unprotected LM coronary artery disease and a SYNTAX score <33 undergoing PCI with the Resolute Onyx zotarolimus-eluting coronary stent, that includes dedicated extra-large vessel platforms. The primary endpoint (EP) was target lesion failure (TLF): a composite of cardiac death, target vessel myocardial infarction (TVMI) and ischaemia-driven target lesion revascularisation (ID-TLR), at 1 year. All events were adjudicated by an independent clinical event committee. An independent core lab analysed all procedural angiograms., Results: A total of 450 patients (mean age 71.8 years, SYNTAX score 24.5±7.2, acute coronary syndrome in 53%) were enrolled in 26 centres. Of these, 77% of subjects underwent PCI with a single-stent and 23% with a 2-stent technique (8% double kissing [DK] crush, 6% culotte, 9% T/T and small protrusion [TAP] stenting). Intravascular imaging guidance was used in 45% (42% intravascular ultrasound [IVUS], 3% optical coherence tomography [OCT]). At 1 year, the primary EP incidence was 5.1% (cardiac death 2.7%, TVMI 2.7%, ID-TLR 2.0%). The definite/probable stent thrombosis rate was 1.1%. In a prespecified adjusted subanalysis, the primary EP incidence was significantly lower in patients undergoing IVUS/OCT-guided versus angio-guided PCI (2.0 vs 7.6%; hazard ratio [HR] 0.28, 95% confidence interval [CI]: 0.13-0.58; p<0.001)., Conclusions: In this large, multicentre, prospective registry, LM PCI with the Resolute Onyx DES showed good safety and efficacy at 1 year, particularly when guided by intracoronary imaging.

Background: During the last decade, thanks to contemporary evidence and technological improvements, the role of interventional cardiology in the field of cardiac conditions that are mainly treated conservatively has grown a lot. In such scenario, drug-resistant arterial hypertension and heart failure (HF) have a significant role, considering the huge number of involved patients and their impact on mortality and quality of life., Methods: This survey was jointly performed by the GISE Young Committee with the support of the SICI-GISE Society and the ICOT group with the aim of evaluating the view of the cardiology community on interventional therapies for arterial hypertension and HF. A web-based questionnaire based on 22 questions was distributed online to SICI-GISE members., Results: The survey was distributed to 1550 physicians with 156 (10%) responses, 58% of whom was under 35 years of age. Renal denervation was available in 49% of Centers, its principal indication was the evidence of severe adverse reactions to anti-hypertensive drugs (80%). Most participants agreed that, compared to past years, there is more understanding of anatomical characteristics and improvement of devices, thus increasing procedural safety; however, main limitations were: appropriate patients' selection criteria (45%), lack of robust evidence (41%) and regulatory (36%) and economical (33%) factors. In the field of HF, this survey enlightened a wide availability of conventional therapies (i.e. mechanical circulatory support, defibrillators, resynchronization) in Italy; on the other side, there is limited availability of innovative devices (i.e. atrial decompression systems, transcatheter left ventricular reshaping). Many participants expressed enthusiastic attitude in this new field, with a look for the need of further evidence in terms of safety and efficacy. Finally, in the treatment of both acute and chronic HF, many participants expressed a problem of limited patient access to advanced therapies, mainly associated with suboptimal networking among institutions., Conclusions: Device-based therapies for arterial hypertension and HF represent a promising option for selected patients; this survey highlights the importance of achieving good quality evidence in both fields, with the goal of proper identification of defined criteria for patients' selection and improvement of procedural and long-term safety and efficacy.

In the last decade, an upsurge of human leishmaniasis has been reported in the Emilia-Romagna region, Northeast Italy. Epidemiologic data have raised doubts about the role of dogs as the main reservoirs for Leishmania infantum . In the present study, a total of 1,077 wild animals were screened for L. infantum DNA in earlobe and spleen samples from 2019 to 2022. The lymph nodes were tested only in 23 animals already positive in the earlobe and/or spleen. A total of 71 (6.6%) animals resulted positive in at least one of the sampled tissues, including 3/18 (16.7%) wolves, 6/39 (15.4%) European hares, 38/309 (12.3%) roe deer, 1/11 (9.1%) red deer, 8/146 (4.9%) wild boars, 13/319 (4.1%) red foxes, 1/54 (1.9%) porcupine, and 1/59 (1.7%) European badger. Most of the infected animals (62/71) tested positive only in the earlobe tissue, only four animals (two roe deer and two wild boars) tested positive only in the spleen, and five animals (three roe deer and two red foxes) resulted positive for both tissues. L. infantum DNA was detected in the lymph nodes of 6/23 animals. L. infantum detection occurred in all seasons associated with low real-time PCR Ct values. Further research is needed in order to clarify the role of wildlife in the re-emerging focus of leishmaniasis in Northeast Italy.

Despite being highly effective in reducing residual mitral regurgitation and improving outcomes, mitral valve transcatheter edge-to-edge repair (MV-TEER) may be associated with high postprocedural residual mitral gradient (rMG). Conflicting results have been reported regarding the relation between rMG and adverse events. This study aimed to evaluate the predictors and the impact of elevated rMG after MV-TEER on clinical events in patients with functional mitral regurgitation (FMR) at 2 years follow-up. We selected a cohort of 864 patients with FMR who were treated with MV-TEER enrolled in the multicentre Italian Society of Interventional Cardiology (GISE) registry of transcatheter treatment of mitral valve regurgitation (GIOTTO). Patients were stratified into tertiles according to rMG. The primary clinical end point was a composite of all-cause death and hospitalization because of heart failure at 2-year follow-up. Overall, 269 patients (31.5%) with an rMG &lt;3 mm Hg, 259 (30.3%) with an rMG ≥3/&lt;4 mm Hg, and 326 (38.2%) with an rMG ≥4 mm Hg were considered. At multivariate logistic regression, ischemic FMR etiology, baseline MG, and the number of implanted clips were independent predictors of an rMG ≥4 mm Hg. Clinical follow-up was available in 570 patients (63.2%). Patients with an rMG ≥4 mm Hg experienced higher rates of the composite end point than patients of the other tertiles (51.1%, vs 42.3% vs 40.8% log-rank test: p = 0.033). In multivariate Cox's regression, both rMG ≥4 mm Hg (hazard ratio 1.54, 95% confidence interval 1.14 to 2.08) and residual mitral regurgitation ≥2+ (hazard ratio 1.36, 95% confidence interval 1.01 to 1.83) were independent predictors of adverse events at 2-year follow-up. In conclusion, we demonstrated that real-world patients who underwent MV-TEER who show an rMG ≥4 mm Hg are at higher risk of death or hospitalization because of heart failure during a 2-year follow-up. Further studies will be needed to confirm our results., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: Mitral-valve transcatheter edge-to-edge repair (MV-TEER) is recommended in patients with severe functional mitral regurgitation (FMR) and in those with degenerative mitral regurgitation (DMR) not eligible to traditional surgery. Patients with a history of previous cardiac surgery are considered at high risk for surgical reintervention, but data are lacking regarding procedural and clinical outcomes., Objective: aim of this study was to assess the efficacy and clinical results of MV-TEER in patients with previous cardiac surgery enrolled in the "multicentre Italian Society of Interventional Cardiology registry of transcatheter treatment of mitral valve regurgitation" (GIOTTO)., Methods: Patients with previous coronary artery bypass grafting (CABG), surgical aortic valve replacement (AVR), or mitral valve repair (MVR) were included. Those with multiple or combined previous cardiac surgeries were excluded. Clinical follow-up was performed at 30 days, 1 year, and 2 years. The primary endpoint was a composite of death or rehospitalization at 1- and 2-year follow-ups., Results: A total of 330 patients enrolled in the GIOTTO registry were considered (CABG 77.9%, AVR 14.2%, and MVR 7.9%). Most patients showed FMR (66.9%), moderate reduction of left ventricular (LV) ejection fraction, and signs of LV dilation. Procedural and device successes were 94.8% and 97%. At 1 and 2 years, the composite endpoint occurred are 29.1% and 52.4%, respectively. The composite outcome rates were similar across the three subgroups of previous cardiac surgery (p = 0.928) and between the FMR and DMR subgroups (p = 0.850) at 2 years. In a multivariate analysis, residual mitral regurgitation (rMR) ≥2+ was the main predictor of adverse events at 1 year (hazard ratio: 1.54 [95% confidence interval, CI: 1.00-2.38]; p = 0.050). This association was confirmed at 2 years of Kaplan-Meier analysis (p = 0.001)., Conclusions: MV-TEER is effective in these patients, regardless of the subtype of previous cardiac surgery and the MR etiology. An rMR ≥2+ is independently associated with adverse outcomes at 1-year follow-up., (© 2022 Wiley Periodicals LLC.)

Background: Complete revascularization (CR) of nonculprit lesions (NCL) is strongly recommended in patients with ST-elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD), but no definitive evidence is available regarding which diagnostic strategy should be preferred. Instantaneous wave-free ratio (iFR) has never been investigated in this setting. We aimed to describe clinical outcomes of a cohort of patients undergoing iFR-guided CR., Methods: Following primary percutaneous coronary intervention (PCI), consecutive patients with STEMI and intermediate NCL were enrolled and destinated to an iFR-guided CR. NCL with iFR ≤ 0.89 underwent PCI while NCL with iFR > 0.89 were deferred. The primary endpoint was NC target lesion failure (NC-TLF) and the secondary endpoint was major adverse cardiovascular events (MACE), at 1-year follow-up., Results: Overall, 209 patients were enrolled (ischemic iFR = 83; nonischemic iFR = 126). Patients with ischemic iFR showed a higher prevalence of traditional cardiovascular risk factors and angiographically determined three-vessel disease. In the entire cohort, NC-TLF and MACE occurred in 6.7% and 10.5% of patients, respectively. Compared to the deferred group, patients with ischemic iFR experienced significantly higher rates of both NC-TLF (3.2% vs. 12.1%; p = 0.021) and MACE (7.1% vs. 16.9%; p = 0.041). These results were mostly driven by increased rates of NC-TLF PCI and further revascularizations in this latter group, while no differences were evident in terms of nonfatal myocardial infarction or death. At multivariable analysis, the strongest predictor of MACE was symptom onset to balloon time (HR = 1.17 [95% CI: 1.04-1.31], p = 0.008)., Conclusions: In our study enrolling STEMI patients with MVD, iFR assessment was feasible and safe. PCI-deferring according to iFR evaluation of NCL was associated with low rates of adverse events. Further randomized studies are needed to investigate the effectiveness of iFR-guided revascularization compared to current practice in this setting., (© 2022 Wiley Periodicals LLC.)

Introduction: In immunocompromised patients, SARS-CoV-2 mRNA vaccine has been used in Italy from the beginning of the vaccination campaign, but several studies have shown that the serological response of onco-hematological patients was reduced compared to healthy subjects, due to the state of immunosuppression because of both underlying disease and administered therapy., Methods: We evaluated the association of anti-SARS-CoV-2 spike IgG titers in 215 hematological patients with clinical and demographic variables to verify if it was possible to identify predictive parameters of serological response, as well as using a control group, consisting of healthy health workers of San Carlo Hospital in Potenza. Anti-SARS-CoV2 IgG titers were evaluated after 30-45 days post second dose vaccine using chemiluminescent microparticle immunoassay technology., Results: Patients with hematological malignancies, compared with the control arm, had both a mean concentration of anti-SARS-CoV-2 IgG significantly lower and a seroconversion rate numerically lower. All chronic lymphatic leukemia patients showed levels of antibody titer below the mean concentration, also in only clinical surveillance patients. Comparing serological response in hematological malignancies, only acute leukemia patients who were off therapy had the highest seroconversion rate among the patients' cohorts and a mean antibody concentration greater than the control arm. Patients treated with steroids and rituximab showed a lower level of anti-SARS-CoV-2 spike IgG. Differences in anti-spike IgG levels among chronic myeloid leukemia patients stratified according to tyrosine kinase inhibitor therapy and molecular response were observed, and they could have interesting implications on the evaluation of the effects of these drugs on the immune system, but having not reached statistical significance at the moment. The cohort of patients who received a stem cell transplant was very heterogeneous because it included different hematological malignancies and different types of transplant; however, a mean concentration of anti-SARS-CoV2 IgG greater than the control arm was reported. Indeed, among patients who performed a transplant for over 6 months only one had a spike IgG concentration below the cutoff., Conclusions: Our data confirm reduced serological response in hematological patients after anti-SARS-CoV-2 vaccination. However, we found a great diversity of SARS-CoV-2 antibody response according to types of pathologies and therapies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Pascale, Nuccorini, Pierri, Di Mare, Fabio, Lerose, Merlino, Schiavo, Amendola, Brucoli, Caputo, Chitarrelli, Cimminiello, Coluzzi, Filardi, Matturro, Vertone, Poggiaspalla, Malaspina, Musuraca, Coralluzzo, Mannarella, Musto, Bellettieri, Martinelli, Cerchione and Pizzuti.)

Background: Pulmonary embolism (PE) represents the third leading acute cardiovascular syndrome in the world and it is burdened with high mortality and morbidity rates. Percutaneous or catheter-based treatments of high- and intermediate-risk patients have garnered interest because of the limitations of both systemic thrombolysis and anticoagulation strategies. However, data on these techniques are heterogeneous and limited to small non-randomized evidences., Methods: This survey was jointly performed by the GISE Young Committee with the support of the SICI-GISE Society and ICOT group with the aim of evaluating the view of the cardiology community on interventional therapies for PE. A web-based questionnaire based on 19 questions was distributed to SICI-GISE and ICOT members., Results: The survey was distributed to 1550 physicians with 220 (14%) responses, 65% from North Italy. Multidisciplinary diagnostic and therapeutic pathways for patients with PE were not available in most centers (56%), and transcatheter treatment was available in 55% of centers, most of them at low volume (<5 percutaneous treatments/year). Among the devices used, mechanical thrombectomy was the predominant one (62%) in the absence of significant differences in the availability of devices within the three Italian geographic macro-areas. Respondents recognize the theoretical benefits of percutaneous treatment of PE, including: improving a prompt hemodynamic stabilization and respiratory exchange (89%) in high-risk patients, avoiding hemodynamic deterioration (39%) and right ventricular dysfunction (51%) in intermediate-risk patients, and reducing hemorrhagic complications related to systemic thrombolysis (36%). According to participants' judgement, the main factors limiting the use of percutaneous transcatheter treatment of PE in clinical practice are the lack of specific operator training (60%), lack of solid clinical data to support it (39%), difficult patient selection (34%), high costs (30%), and risk of procedural complications (26%)., Conclusions: Currently, transcatheter treatment of PE appears to be widely supported but poorly used in clinical practice. Solid evidences are needed regarding the safety and efficacy profile of the different available devices, the identification of patient selection criteria, alongside the enhancement of the availability of techniques and technologies.

Background It is unknown whether contemporary drug-eluting stents have a similar safety profile in high bleeding risk patients treated with 1-month dual antiplatelet therapy following percutaneous coronary interventions. Methods and Results We performed an interventional, prospective, multicenter, single-arm trial, powered for noninferiority with respect to an objective performance criterion to evaluate the safety of percutaneous coronary interventions with Synergy bioresorbable-polymer everolimus-eluting stent followed by 1-month dual antiplatelet therapy in patients with high bleeding risk. In case of need for an oral anticoagulant, patients received an oral anticoagulant in addition to a P2Y 12 inhibitor for 1 month, followed by an oral anticoagulant only. The primary end point was the composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 1-year follow-up. The study was prematurely interrupted because of slow recruitment. From April 2017 to October 2019, 443 patients (age, 74.8±9.2 years; women, 29.1%) at 10 Italian centers were included. The 1-year primary outcome occurred in 4.82% (95% CI, 3.17%-7.31%) of patients, meeting the noninferiority compared with the predefined objective performance criterion of 9.4% and the noninferiority margin of 3.85% ( P noninferiority <0.001) notwithstanding the lower-than-expected sample size. The rates of cardiac death, myocardial infarction, and definite or probable stent thrombosis were 1.88% (95% CI, 0.36%-2.50%), 3.42% (95% CI, 2.08%-5.62%), and 0.94% (95% CI, 0.35%-2.49%), respectively. Conclusions Among high bleeding risk patients undergoing percutaneous coronary interventions with the Synergy bioresorbable-polymer everolimus-eluting stent, a 1-month dual antiplatelet therapy regimen is safe, with low rates of ischemic and bleeding events.

Severe acute respiratory syndrome coronavirus-2 can affect the cardiovascular system yielding a wide range of complications, including acute myocardial injury. The myocardium can be damaged by direct viral invasion or indirect mechanisms, sustained by systemic inflammation, immune-mediated response, and dysregulation of the renin-angiotensin system. Myocardial injury affects about one-quarter of patients with COVID-19, can manifest even in the absence of previous cardiovascular disease, and is associated to higher mortality rates and long-term sequelae. This review describes the pathophysiological mechanisms of myocardial injury and infarction and discusses the main clinical outcomes and diagnostic challenges associated with myocardial damage during COVID-19., (Copyright © 2021 Elsevier Inc.

Razionale. In Italia la pandemia COVID-19 ha determinato importanti riorganizzazioni logistiche nell'erogazione delle cure ospedaliere e di specialistica ambulatoriale. Ciò ha spinto clinici e decisori pubblico-amministrativi della Sanità ad adottare nuovi modelli organizzativi in molteplici scenari clinici. Materiali e metodi. Il registro OIBOH (Optimal Intensification therapy in a Broad Observed High risk patient population with coronary disease) è uno studio osservazionale "cross-sectional" condotto in vari centri italiani di cardiologia ambulatoriale per valutare durante la pandemia COVID-19 la capacità di identificare in breve tempo i pazienti ad altissimo rischio cardiovascolare residuo dopo un evento coronarico recente (<12 mesi). Successivamente alla valutazione clinica iniziale, venivano arruolati i pazienti ritenuti ad altissimo rischio, registrando le caratteristiche cliniche e di trattamento in una scheda di raccolta dati elettronica.Risultati. Al registro hanno partecipato 134 centri di cardiologia ambulatoriale che hanno arruolato 1428 pazienti su 3227 esaminati fra quelli che avevano avuto accesso ad una visita cardiologica durante la pandemia nel periodo ottobre 2020-marzo 2021. Il criterio di arruolamento era costituito dall'aver avuto una diagnosi di coronaropatia confermata angiograficamente negli ultimi 12 mesi, per sindrome coronarica acuta (SCA) o cronica (SCC). La SCA come evento indice era presente nel 93% dei pazienti arruolati mentre la SCC nel 7%. L'età media era 67 ± 10 anni, il 25% era di sesso femminile. Il 96.1% dei pazienti con SCA e il 67.6% dei pazienti con SCC sono stati sottoposti a rivascolarizzazione coronarica. Il 46% e 47% dei pazienti con SCA e SCC, rispettivamente, era diabetico. Oltre il 65% dei pazienti presentava una malattia coronarica multivasale. È stata osservata una importante prevalenza di arteriopatia periferica (17.5% nei pazienti con SCA e 19.6% nei pazienti con SCC). I valori di pressione arteriosa e frequenza cardiaca risultavano ben controllati (128 ± 25.2 mmHg e 65 ± 12.3 b/min nei pazienti con SCA; 127 ± 23.4 mmHg e 67 ± 13.2 b/min nei pazienti con SCC). Viceversa, è stato riportato uno scarso controllo dei livelli di colesterolemia LDL, con un valore medio di 88.8 ± 38.6 mg/dl nei pazienti con SCA e 86 ± 36.6 mg/dl nei pazienti con SCC. Solo il 16.4% dei pazienti con SCA raggiungeva i livelli raccomandati dalle attuali linee guida europee. Nonostante l'estensivo uso di statine (>90%), si è rilevato un utilizzo limitato dell'associazione statina ad alta intensità + ezetimibe (solo il 22.4% dei pazienti). Estremamente basso è stato l'utilizzo di inibitori di PCSK9 (2.5%). La duplice terapia antiaggregante piastrinica (DAPT) è risultata complessivamente ben condotta fin dalla dimissione ospedaliera. Nei pazienti in DAPT, l'inibitore P2Y12 più utilizzato è risultato il ticagrelor alla dose di 90 mg, soprattutto dopo un evento coronarico acuto (in circa l'80% dei pazienti con SCA). Nella stragrande maggioranza dei casi (>90%) i cardiologi ambulatoriali hanno posto indicazione a prosecuzione della DAPT oltre i 12 mesi con aspirina e ticagrelor 60 mg bid. Conclusioni. La gestione del paziente con coronaropatia in fase cronica stabilizzata è molto complessa. Tale complessità logistico-gestionale si è accentuata durante la pandemia COVID-19. Il registro OIBOH ha evidenziato un'ottima capacità di identificare le problematiche clinico-prognostiche delle cardiologie ambulatoriali italiane, specie nei pazienti ad altissimo rischio residuo. Rimangono importanti aree di miglioramento come uno stretto controllo della colesterolemia LDL, mentre altre raccomandazioni delle linee guida, come la prosecuzione della DAPT con ticagrelor 60 mg oltre i 12 mesi, risultano ben applicate. L'implementazione dell'assistenza con la medicina digitale e l'intelligenza artificiale potrebbe migliorare di molto la performance dei clinici.

Objectives: To evaluate the short- and long-term clinical and echocardiographic outcomes of the percutaneous closure of the patent foramen ovale (PFO) with an atrial septal aneurysm (ASA) using 2 different devices., Methods: We enrolled 100 patients with PFO and ASA. Fifty consecutive patients had transcatheter closure of the PFO with the Gore Cardioform septal occluder (GSO) (Gore Medical) and a second group of 50 consecutive patients with the Amplatzer PFO occluder (APO) (Abbott). A clinical and transthoracic echocardiographic follow-up was performed at 1, 3, 6, and 12 months after the implant procedure. The primary endpoint was the incidence of moderate-to-severe residual right-to-left shunting (rRLS) at the 6-month follow-up. The procedural results and the recurrence of embolic events at 1 year were also investigated., Results: The procedure was successful in all patients. The immediate postprocedural moderate-to-severe rRLS incidence was similar between the 2 groups (GSO 14% vs APO 12%; P=NS) as well as the incidence of moderate-to-severe rRLS at the 6-month follow-up (GSO 4% vs APO 4%; P=non-significant). In only 1 patient of the GSO group, there was a persistent moderate rRLS at the 1-year follow-up. The 6-month and 1-year complete occlusion rate for all subjects was 93% and 96%, respectively. No devices embolized and no death or recurrent embolic events were observed during hospitalization through the 1-year follow-up., Conclusions: GSO and APO devices appear to be safe and effective devices for the percutaneous closure of a PFO with ASA, showing similar results for the presence of rRLS at the 6-month follow-up, complete occlusion rate, and clinical embolic recurrences.

Background: TAVR is a safe alternative to surgical aortic valve replacement (SAVR); however, sex-related differences are still debated. This research aimed to examine gender differences in a real-world transcatheter aortic valve replacement (TAVR) cohort., Methods: All-comer aortic stenosis (AS) patients undergoing TAVR with a Medtronic valve across 19 Italian sites were prospectively included in the Italian Clinical Service Project (NCT01007474) between 2007 and 2019. The primary endpoint was 1-year mortality. We also investigated 3-year mortality, and ischemic and hemorrhagic endpoints, and we performed a propensity score matching to assemble patients with similar baseline characteristics., Results: Out of 3821 patients, 2149 (56.2%) women were enrolled. Compared with men, women were older (83 ± 6 vs. 81 ± 6 years, p < 0.001), more likely to present severe renal impairment (GFR ≤ 30 mL/min, 26.3% vs. 16.3%, p < 0.001) but had less previous cardiovascular events (all p < 0.001), with a higher mean Society of Thoracic Surgeons (STS) score (7.8% ± 7.1% vs. 7.2 ± 7.5, p < 0.001) and a greater mean aortic gradient (52.4 ± 15.3 vs. 47.3 ± 12.8 mmHg, p < 0.001). Transfemoral TAVR was performed more frequently in women (87.2% vs. 82.1%, p < 0.001), with a higher rate of major vascular complications and life-threatening bleeding (3.9% vs. 2.4%, p = 0.012 and 2.5% vs. 1.4%, p = 0.024). One-year mortality differed between female and male (11.5% vs. 15.0%, p = 0.002), and this difference persisted after adjustment for significant confounding variables (Adj.HR1yr 1.47, 95%IC 1.18-1.82, p < 0.001). Three-year mortality was also significantly lower in women compared with men (19.8% vs. 24.9%, p < 0.001) even after adjustment for age, STS score, eGFR, diabetes and severe COPD (Adj.HR3yr 1.42, 95%IC 1.21-1.68, p < 0.001). These results were confirmed in 689 pairs after propensity score matching., Conclusion: Despite higher rates of peri-procedural complications, women presented better survival than men. This better adaptive response to TAVR may be driven by sex-specific factors.

In this study, internal organs (tongue, intestine, and spleen) of 23 free-ranging Italian wolves ( Canis lupus italicus ) found dead between 2017 and 2019 were tested for Carnivore protoparvovirus 1 , Canine adenovirus (CAdV), and Canine circovirus (CanineCV) using real-time PCR assays. Genetic characterisation of the identified viruses was carried out by amplification, sequencing, and analysis of the complete viral genome or informative viral genes. All the wolves tested positive for at least one of the DNA viruses screened, and 11/23 were coinfected. Carnivore protoparvoviruses were the most frequently detected viruses (21/23), followed by CanineCV (11/23) and CAdV (4/23). From the analysis of the partial VP2 gene of 13 carnivore protoparvoviruses, 12 were canine parvovirus type 2b, closely related to the strains detected in dogs and wild carnivores from Italy, and one was a feline panleukopenia-like virus. Of the four CAdV identified, two were CAdV-1 and two were CAdV-2. The complete genome of seven CanineCVs was sequenced and related to the CanineCV identified in dogs, wolves, and foxes worldwide. Close correlations emerged between the viruses identified in wolves and those circulating in domestic dogs. Further studies are needed to investigate if these pathogens may be potentially cross-transmitted between the two species.

Background: The optimal management of patients with ST-elevation acute coronary syndromes and multivessel coronary artery disease is challenging. There is a growing body of evidence supporting invasive functional evaluation of multivessel disease with FFR or iFR, which it has been added to the literature. In this regard, the WAVE Study recently demonstrated the diagnostic accuracy of instantaneous wave-free ratio (iFR) functional assessment of non-culprit lesions in multivessel patients with STEMI. However, no studies have still verified the long-term clinical impact of an iFR-guided revascularization in this setting of patients., Methods: Patients undergoing primary PCI for STEMI and presenting multivessel disease will be enrolled. After the treatment of the culprit lesion, an iFR-guided functional assessment of non-culprit lesions will be done if iFR≤0.89 PCI will be performed during the index procedure or staged. Conversely, iFR>0.89 will direct the patient towards a conservative approach., Results: The study start date was May 1, 2018. The enrollment phase was completed on March 30, 2020. The primary endpoint is the occurrence of target lesion failure (TLF), a composite of cardiovascular death, non-fatal myocardial infarction, and ischemia-driven revascularization of the vessel previously assessed with iFR. Secondary endpoints include MACE (cardiovascular death, non-fatal MI, any revascularization)., Conclusions: The aim of the present study was to evaluate the long-term clinical impact of an iFR-guided revascularization of the non-culprit lesions in STEMI patients with multivessel coronary artery disease.

Introduction: Compensation programs are an important tool for mitigating conflicts between farmers and large predators. However, they present significant weaknesses and faults. For years, the EU has been prioritizing programs for the prevention of damage caused by large carnivores, rather than compensation programs, introducing compulsory compensation for the purposes of decision EC (2019) 772 of 29/01/19. This manuscript reports the experience with the wolf damage prevention programs in an Italian region, Emilia-Romagna, which implemented a pilot project, adopting a new method to interface with the farmers involved in the prevention programs., Methods: Starting in 2014, a project aimed at spreading prevention measures was financed through regional and European resources, accompanied by resources sharing and technical assistance with breeders from the regional body. In detail, (i) standardized types of intervention were defined and technical assistance was structured; (ii) ex post, the effectiveness of the interventions carried out was assessed; and (iii) the difficulties encountered in using the various financing instruments were analyzed., Results: Overall, 298 farms were analyzed, of which 166 applied for regional calls and 132 applied for European funds. The mitigation measures produced a reduction in predatory phenomena of 93.4%, i.e., from 528 to 35 predations over a period of 4-6 years. This study shows that more than one-third of the farmers were forced to abandon the two tenders, mainly due to the lack of liquidity in anticipating the prevention measures., Conclusion: In the years examined by this study, the prevention programs in the Emilia-Romagna region, due to the technical support offered, proved to be a functional and effective tool, capable of significantly reducing the wolf predation on livestock. However, this work highlights the high percentage of denials of mitigation measures by farmers interested in adopting these tools, stressing the need for regional agencies to focus on new policies that can provide advance economic resources to farmers and solve the authorization problems related to the various bodies with which the participant in the tenders must interface.

Background: This Phase I, two-part, first-in-human study assessed safety/tolerability and pharmacokinetics/pharmacodynamics of single-ascending doses (SAD) and multiple doses (MD) of the oral toll-like receptor-7 agonist, JNJ-64794964 (JNJ-4964) in healthy adults., Methods: In the SAD phase, participants received JNJ-4964 0.2 ( N = 6), 0.6 ( N = 6), 1.25 ( N = 8) or 1.8 mg ( N = 6) or placebo ( N = 2/dose cohort) in a fasted state. Food effect was evaluated for the 1.25 mg cohort following ≥6 weeks washout. In the MD phase, participants received JNJ-4964 1.25 mg ( N = 6) or placebo ( N = 2) weekly (fasted) for 4 weeks. Participants were followed-up for 4 weeks., Results: No serious adverse events (AEs) occurred. 10/34 (SAD) and 5/8 (MD) participants reported mild-to-moderate (≤Grade 2), transient, reversible AEs possibly related to JNJ-4964. Five (SAD) participants had fever/flu-like AEs, coinciding with interferon-α serum levels ≥100 pg/mL and lymphopenia (<1 × 10 9 /L), between 24-48 h after dosing and resolving approximately 96 h after dosing. One participant (MD) had an asymptomatic Grade 1 AE of retinal exudates (cotton wool spots) during follow-up, resolving 6 weeks after observation. JNJ-4964 exhibited dose-proportional pharmacokinetics, with rapid absorption (t max 0.5-0.75 h) and distribution, and a long terminal half-life (150-591 h). Overall, no significant differences in JNJ-4964 pharmacokinetic parameters were observed in the fed versus fasted state. JNJ-4964 dose-dependently and transiently induced cytokines with potential anti-HBV activity, including interferon-α, IP-10, IL-1 RA, and/or MCP-1, and interferon-stimulated genes (ISG15, MX1, and OAS1) in serum., Conclusions: In healthy adults, JNJ-4964 was generally well-tolerated, exhibited dose-proportional pharmacokinetics and induced cytokines/ISGs, with possible anti-HBV activity.

Background: Coronavirus disease 2019 (COVID-19) has caused an unprecedented change in the apparent epidemiology of acute coronary syndromes (ACS). However, the interplay between this disease, changes in pollution, climate, and aversion to activation of emergency medical services represents a challenging conundrum. We aimed at appraising the impact of COVID-19, weather, and environment features on the occurrence of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) in a large Italian region and metropolitan area., Methods and Results: Italy was hit early on by COVID-19, such that state of emergency was declared on January 31, 2020, and national lockdown implemented on March 9, 2020, mainly because the accrual of cases in Northern Italy. In order to appraise the independent contribution on changes in STEMI and NSTEMI daily rates of COVID-19, climate and pollution, we collected data on these clinical events from tertiary care cardiovascular centers in the Lazio region and Rome metropolitan area. Multilevel Poisson modeling was used to appraise unadjusted and adjusted effect estimates for the daily incidence of STEMI and NSTEMI cases. The sample included 1448 STEMI and 2040 NSTEMI, with a total of 2882 PCI spanning 6 months. Significant reductions in STEMI and NSTEMI were evident already in early February 2020 (all p<0.05), concomitantly with COVID-19 spread and institution of national countermeasures. Changes in STEMI and NSTEMI were inversely associated with daily COVID-19 tests, cases, and/or death (p<0.05). In addition, STEMI and NSTEMI incidences were associated with daily NO2, PM10, and O3 concentrations, as well as temperature (p<0.05). Multi-stage and multiply adjusted models highlighted that reductions in STEMI were significantly associated with COVID-19 data (p<0.001), whereas changes in NSTEMI were significantly associated with both NO2 and COVID-19 data (both p<0.001)., Conclusions: Reductions in STEMI and NSTEMI in the COVID-19 pandemic may depend on different concomitant epidemiologic and pathophysiologic mechanisms. In particular, recent changes in STEMI may depend on COVID-19 scare, leading to excess all-cause mortality, or effective reduced incidence, whereas reductions in NSTEMI may also be due to beneficial reductions in NO2 emissions in the lockdown phase., Competing Interests: Declaration of Competing Interest Prof. Biondi-Zoccai has consulted for Cardionovum, Bonn, Germany, InnovHeart, Milan, Italy, Meditrial, Rome, Italy, and Replycare, Rome, Italy., (Copyright © 2020 Elsevier B.V.

Background: Strong epidemiologic evidence has highlighted the role of pollution, on top of adverse climate features, as a novel cardiovascular risk factor. However, mechanistic proof that reducing pollution may be beneficial to prevent atherothrombotic events is limited. We aimed at appraising the impact of temporary traffic bans in a large metropolitan area on the risk of acute coronary syndromes., Methods: Aggregate and anonymized data from 15 tertiary cardiac care centers were obtained detailing precoronavirus disease 2019 (COVID-19) daily cases of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), including those treated with percutaneous coronary intervention (PCI). Data on pollutants and climate were sought for the same days. Mixed level regression was used to compare the week before vs after the traffic ban (Fortnight analysis), the 3 days before vs. after (Weekly analysis) and the Sunday before vs. after (Sunday analysis)., Results: A total of 8 days of temporary traffic bans were included, occurring between 2017 and 2020, totaling 802 STEMI and 1196 NSTEMI in the Fortnight analysis, 382 STEMI and 585 in the Weekly analysis, and 148 STEMI and 210 NSTEMI in the Sunday analysis.Fortnight and Sunday analyses did not disclose a significant impact of traffic ban on STEMI or NSTEMI (all P>0.05). Conversely, Weekly analysis showed non-significant changes for STEMI, but a significant decrease in daily NSTEMI when comparing the 3 days before the traffic ban with the ban day (P=0.043), as well as the 3 days before vs. the 3 days after the ban (P=0.025). No statistically significant effect of traffic ban was found at Fortnight, Weekly or Sunday analyses for daily mean concentrations of benzene, carbon monoxide, nitric oxide, nitrogen dioxide, ozone, sulfur dioxide, particulate matter (PM) <2.5 µm or PM <10 µm (all P>0.05). However, minimum daily concentrations showed a significant reduction of ozone during the ban in comparison to the week preceding it (P=0.034), nitric oxide during the ban in comparison to the 3 days preceding it (P=0.046), and an increase in benzene during the ban in comparison to the Sunday before (P=0.039)., Conclusions: Temporary traffic ban may favorably reduce coronary atherothrombotic events, and in particular NSTEMI, even if not globally and immediately impacting on environmental pollution. Further controlled studies are required to confirm and expand this hypothesis-generating results.

Nonculprit lesions are frequently observed in patients with ST-segment elevation myocardial infarction. Results from recent randomized clinical trials suggest that complete revascularization after ST-segment elevation myocardial infarction improves outcomes. In this state-of-the-art paper, the authors review these trials and consider how best to determine which nonculprit lesions require revascularization and when this should be performed., (Copyright © 2020 American College of Cardiology Foundation.
