The hypertrophic cardiomyopathy phenotype encompasses a heterogeneous spectrum of genetic and acquired diseases characterized by the presence of left ventricular hypertrophy in the absence of abnormal cardiac loading conditions. This "umbrella diagnosis" includes the "classic" hypertrophic cardiomyopathy (HCM), due to sarcomere protein gene mutations, and its phenocopies caused by intra- or extracellular deposits, such as Fabry disease (FD) and cardiac amyloidosis (CA). All these conditions share a wide phenotypic variability which results from the combination of genetic and environmental factors and whose pathogenic mediators are poorly understood so far. Accumulating evidence suggests that inflammation plays a critical role in a broad spectrum of cardiovascular conditions, including cardiomyopathies. Indeed, inflammation can trigger molecular pathways which contribute to cardiomyocyte hypertrophy and dysfunction, extracellular matrix accumulation, and microvascular dysfunction. Growing evidence suggests that systemic inflammation is a possible key pathophysiologic process potentially involved in the pathogenesis of cardiac disease progression, influencing the severity of the phenotype and clinical outcome, including heart failure. In this review, we summarize current knowledge regarding the prevalence, clinical significance, and potential therapeutic implications of inflammation in HCM and two of its most important phenocopies, FD and CA.

Introduction: Left ventricular (LV) hypertrophy is the main feature of cardiac involvement in Anderson-Fabry disease (FD), but the right ventricle (RV) is also frequently affected. Previous studies failed to demonstrate an independent association between conventional parameters of RV performance and outcomes in FD. Nevertheless, if RV free wall strain (RV-FWS), assessed by 2D speckle tracking analysis, may provide a better prognostication is currently unknown. Methods: We retrospectively evaluated the association between RV-FWS and the occurrence of cardiovascular events in a cohort of 56 patients with FD. The study endpoint comprises cardiovascular mortality, severe heart failure symptoms, new-onset atrial fibrillation and major arrhythmias requiring device implantation. Results: Reduced RV-FWS, defined by values lower than 23%, was found in 25 (45%) patients. During a median follow-up of 47 months, 16 (29%) patients met the study endpoint. A ROC-curve analysis confirmed the threshold of reduced RV-FWS (<23%) as the best cut-off for predicting cardiovascular events, but with a lower power compared to left-sided parameters. On univariable Cox regression analysis, RV-FWS, expressed as continuous variable, was significantly associated with the study endpoint (HR: 0.795, 95% CI: 0.710–0.889, p < 0.001). However, RV-FWS did not retain a significant association with outcomes, after adjustment for LV global longitudinal strain or indexed left atrial volume (p = 0.340 and p = 0.289 respectively). Conclusions: RV-FWS was not independently associated with the occurrence of cardiovascular events in FD, confirming previous observations that prognosis is mainly driven by the severity of LV cardiomyopathy.

Background: Cardiovascular (CV) diseases are a cause of increased long-term morbidity and mortality in childhood cancer survivors (CCSs) treated with anthracyclines. These drugs may affect not only the heart, but also the vascular system. Left ventricular-arterial coupling (LVAC) represents a reliable parameter of altered ventricular and vascular performance, with validated prognostic value and never investigated in this setting. Aim of this study was to assess, in CCSs and matched controls, LVAC changes, performed with different echocardiographic modalities, and their relationship with endothelial function. Methods: Twenty survivors treated with anthracyclines for childhood malignancies and a matched control group of 20 healthy subjects were enrolled. Arterial elastance (Ea), end-systolic elastance (Ees), Ea/Ees ratio, as well as three-dimensional (3D) LVAC (assessed by measurement of End Systolic Volume [ESV]/Stroke Volume [SV] ratio) were performed at rest. Endothelial function was evaluated by measurement of flow-mediated dilatation (FMD) of the brachial artery. Results: 3D SV and 3D ESV/SV ratio resulted respectively significantly lower and higher in CCSs than in controls, while Ea, Ees and Ea/Ees ratio were not different among groups. A positive correlation between 3D ESV/SV ratio and cumulative anthracycline doses, as well as with time after drug exposure were also found. Mean FMD was similar in CCSs and controls (8.45 ± 1.79 versus 9.41 ± 3.41, p = 0.34). Conclusions: In conclusion, conventional LVAC parameters were not shown to be significantly different between CCSs and controls; however, 3D SV and LVAC were significantly impaired in our population. In these patients, endothelial function was comparable to controls. Larger validation studies are therefore needed.

PurposeTo prospectively compare changes in myocardial blood flow (MBF) and myocardial flow reserve (MFR) in multivessel coronary artery disease (MVCAD) patients undergoing incomplete revascularization (IR) versus complete revascularization (CR) by coronary artery bypass grafting (CABG).MethodsSeven male patients (age 68 +/- 9 years) with MVCAD underwent myocardial perfusion PET/CT with [13N]ammonia before and at least 4 months after CABG. Segmental resting and stress MBF as well as MFR were measured. Resting and during stress left ventricle ejection fraction (LVEF) were also calculated.ResultsThree patients (43%) underwent CR and four (57%) IR. Among 119 myocardial segments, 101 (85%) were revascularized, and 18 (15%) were not. After CABG, stress MBF (mL/min/gr) and MFR are significantly increased in all myocardial segments, with a greater increase in the revascularized segments (p = 0.013). In both groups, LVEF significantly decreased during stress at baseline PET (p = 0.04), but not after CABG.ConclusionStress MBF and MFR significantly improve after CABG in both revascularized and not directly revascularized myocardial segments. IR strategy may be considered in patients with high surgical risk for CR.

OBJECTIVE: SARS-CoV-2 disease (COVID-19) has become a pandemic disease, determining a public health emergency. The use of artificial intelligence in identifying easily available biomarkers capable of predicting the risk for severe disease may be helpful in guiding clinical decisions. The aim of the study was to investigate the ability of interleukin (IL)-6, troponin I, and D-dimer to identify patients with COVID-19 at risk for intensive care unit (ICU)-admission and death by using a machine-learning predictive model. PATIENTS AND METHODS: Data on demographic characteristics, underlying comorbidities, symptoms, physical and radiological findings, and laboratory tests have been retrospectively collected from electronic medical records of patients admitted to Policlinico A. Gemelli Foundation from March 1, 2020, to September 15, 2020, by using artificial intelligence techniques. RESULTS: From an initial cohort of 425 patients, 146 met the inclusion criteria and were enrolled in the study. The in-hospital mortality rate was 15%, and the ICU admission rate was 41%. Patients who died had higher troponin I (p-value<0.01) and IL -6 values (p-value=0.04), compared to those who survived. Patients admitted to ICU had higher lev- els of troponin I (p-value<0.01) and IL-6 (p-val- ue<0.01), compared to those not admitted to ICU. Threshold values to predict in-hospital mortality and ICU admission have been identified. IL-6 levels higher than 15.133 ng/L have been associated with a 22.91% risk of in-hospital mortality, and IL-6 levels higher than 25.65 ng/L have been as- sociated with a 56.16% risk of ICU admission. Troponin I levels higher than 12 ng/L have been associated with a 26.76% risk of in-hospital mortality and troponin I levels higher than 12 ng/L have been associated with a 52.11% risk of ICU admission. CONCLUSIONS: Levels of IL-6 and troponin I are associated with poor COVID-19 outcomes. Cut-off values capable of predicting in-hospi- tal mortality and ICU admi

Objective: Coronavirus disease 2019 (COVID-19) has evolved into a global pandemic, affecting a wide range of medical and surgical specialties. During COVID-19, we assisted in the reallocation of medical resources and services, as well as social distancing measures, and many patients with chronic diseases and comorbidities may have experienced difficulties in obtaining the correct medical care. The aim of the study was to investigate the impact of the COVID-19 pandemic on major adverse cardiovascular events (MACE) and major adverse limb events (MALE) in patients with peripheral arterial disease (PAD) and chronic limb-threatening ischemia (CLTI), compared to previous years. Patients and methods: We evaluated 1,335 hospital admissions of 877 patients with PAD admitted to Policlinico A. Gemelli Hospital between January 2017 and February 2020 and 368 hospital admissions of 272 patients with PAD admitted to the Policlinico A. Gemelli Hospital between March 2020 and March 2021. Data on demographic characteristics, comorbidities, symptoms, physical and radiological findings, laboratory tests, and routine visits before or after discharge were collected from electronic medical records. Results: Emergency room (ER) admissions among PAD patients during COVID-19 were higher than before the pandemic [190 (51.63%) vs. 579 (43.37%), p = 0.01]. A MACE was found in 78 (5.84%) pre-pandemic hospitalizations and 126 (34.24%) pandemic hospitalizations (p < 0.01). A MALE was identified in 942 (70.56%) pre-pandemic hospitalizations and 331 (89.95%) pandemic hospitalizations (p < 0.01). Amputation rates during the pandemic were higher than before the pandemic [80 (21.74%) vs. 191 (14.31%), p < 0.01]. The number of in-hospital deaths did not differ between the pandemic and pre-pandemic periods [11 (2.99%) vs. 51 (3.82%), p = 0.55]. Conclusions: In patients with PAD and CLTI, the number of MACE, MALE, and amputations was higher during the COVID-19 period compared to the thr

Objective: Global longitudinal strain (GLS) predicts major adverse events in ST-segment elevation myocardial infarction (STEMI) and aortic stenosis (AS). Different cut-off values and different end-points have been proposed for prognostic stratification. We aimed to verify whether a single GLS cut-off value can be used to identify increased risk of all-cause death in STEMI and AS.Patients and methods: One-hundred- seventeen successfully treated first STEMI (age 63.8 +/- 12.5 yrs, 70% men) and 64 AS (age 80.3 +/- 6.9 yrs, 44% men) patients, undergoing echocardiography before discharge and before AS treatment, respectively, were retrospectively analyzed. GLS was analyzed, together with pulmonary artery systolic pressure (PASP), Killip class and Genereux stage. End-point was all-cause death at 6-month follow-up.Results: All-cause death occurred in 4 (3.4%) STEMI and 5 (7.8%) AS patients (p=ns). AS patients who died had GLS similar to died STEMI patients (9.7 +/- 2.1 vs. 11.3 +/- 1.7, p=ns). GLS cut-off <= 12% predicted death with 89% sensitivity and 70% specificity (AUC 0.84, p=0.001): STEMI and AS patients with GLS <= 12% had worse survival than STEMI and AS patients with GLS >12% (log-rank p=0.001). At multivariate Cox regression analysis, lower GLS values independently predicted death (HR 0.667, 95% CI 0.451-0.986, p=0.042), and the prediction model was improved when GLS was added to old age, significant comorbidities, PASP and Killip/Genereux stage (chi 2 6.691 vs. 1.364, p=0.010).Conclusions: Died patients with STEMI and AS show similar values of GLS. A unique cut-off value of GLS can reliably be used to stratify the risk of all-cause death at 6-month follow-up in both two clinical settings.

BackgroundThe present study investigates whether epigenetic differences emerge in the heart of patients undergoing cardiac surgery for an aortic valvular replacement (AVR) or coronary artery bypass graft (CABG). An algorithm is also established to determine how the pathophysiological condition might influence the human biological cardiac age.ResultsBlood samples and cardiac auricles were collected from patients who underwent cardiac procedures: 94 AVR and 289 CABG. The CpGs from three independent blood-derived biological clocks were selected to design a new blood- and the first cardiac-specific clocks. Specifically, 31 CpGs from six age-related genes, ELOVL2, EDARADD, ITGA2B, ASPA, PDE4C, and FHL2, were used to construct the tissue-tailored clocks. The best-fitting variables were combined to define new cardiac- and blood-tailored clocks validated through neural network analysis and elastic regression. In addition, telomere length (TL) was measured by qPCR. These new methods revealed a similarity between chronological and biological age in the blood and heart; the average TL was significantly higher in the heart than in the blood. In addition, the cardiac clock discriminated well between AVR and CABG and was sensitive to cardiovascular risk factors such as obesity and smoking. Moreover, the cardiac-specific clock identified an AVR patient's subgroup whose accelerated bioage correlated with the altered ventricular parameters, including left ventricular diastolic and systolic volume.ConclusionThis study reports on applying a method to evaluate the cardiac biological age revealing epigenetic features that separate subgroups of AVR and CABG.

Echocardiography is the most common diagnostic tool to screen for Fabry cardiomyopathy as it is fast, non-invasive, low-cost, widely available, easily applicable and reproducible. Echocardiography is the first-line investigation, being useful in all the stages of the disease: (1) in gene-positive patients, to unveil signs of early cardiac involvement and allowing timely treatment; (2) in patients with overt cardiomyopathy to estimate the severity of cardiac involvement, the possible related complications, and the effect of treatment. Recently, advanced echocardiographic techniques, such as speckle tracking analysis, are offering new insights in the assessment of Fabry disease patients and in the differential diagnosis of cardiomyopathies with hypertrophic phenotype. The aim of this review is to provide a comprehensive overview on the cardiac structural and functional abnormalities described in Fabry disease by means of echocardiography.

This paper describes the development of the disposables and accessories for ROSES (Robotic System for Endovascular Surgery). Initially developed exclusively for transcatheter percutaneous coronary angioplasty, it was later modified, initially leaving the components for angioplasty substantially unchanged to extend its use to endovascular transcatheter surgery. These disposables are used to translate gear rotations into catheter or guide wire advancement or retraction and rotation of their body through friction wheels. The use of a new cart was necessary for endovascular surgery, to which a system to measure forces opposed by the patient’s body to catheter advancement was added. Moreover, since some endovascular catheters present with large diameters, minor mechanical modifications were also performed on the robot actuator (RA), previously defined as a slave, in order to allow large catheters to be pushed, such as those needed for the repair of some big aneurysms or for TAVI. However, in doing this, the possibility of separating the disposables into two components, upper and lower, was found, which allows the extraction of the disposable without having to remove the catheter or guide wire already positioned. Finally, the disposables, whose development is illustrated here, were subjected to various versions and tests and the results are reported.

Background: A pre-operative shower is recommended before surgery to prevent surgical site infections (SSIs). Methods: We modelled the occurrence of SSIs and the potential savings for patients undergoing an antimicrobial soap (AS) shower prior to surgery at a French University Results: AS shower prevented 209 SSIs, generating a potential saving of ???632,210 per year. Results grouped by type of surgery showed annual savings of ???26,537, ???20,520 and ???14,377 for orthopaedic, gynaecologic and obstetric, and digestive surgery, respectively. Conclusions: Despite the lack of published data surrounding the efficacy of AS in preventing SSIs, we demonstrated the potential savings and benefits of generalizing AS before surgical interventions. ?? 2022 The Healthcare Infection Society.

Dietary risk factors play a fundamental role in the prevention and progression of atherosclerosis and PAD (Peripheral Arterial Disease). The impact of nutrition, however, defined as the process of taking in food and using it for growth, metabolism and repair, remains undefined with regard to PAD. This article describes the interplay between nutrition and the development/progression of PAD. We reviewed 688 articles, including key articles, narrative and systematic reviews, meta-analyses and clinical studies. We analyzed the interaction between nutrition and PAD predictors, and subsequently created four descriptive tables to summarize the relationship between PAD, dietary risk factors and outcomes. We comprehensively reviewed the role of well-studied diets (Mediterranean, vegetarian/vegan, low-carbohydrate ketogenic and intermittent fasting diet) and prevalent eating behaviors (emotional and binge eating, night eating and sleeping disorders, anorexia, bulimia, skipping meals, home cooking and fast/ultra-processed food consumption) on the traditional risk factors of PAD. Moreover, we analyzed the interplay between PAD and nutritional status, nutrients, dietary patterns and eating habits. Dietary patterns and eating disorders affect the development and progression of PAD, as well as its disabling complications including major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Nutrition and dietary risk factor modification are important targets to reduce the risk of PAD as well as the subsequent development of MACE and MALE.

Aims: Human epicardial adipose tissue, a dynamic source of multiple bioactive factors, holds a close functional and anatomic relationship with the epicardial coronary arteries and communicates with the coronary artery wall through paracrine and vasocrine secretions. We explored the hypothesis that T-cell recruitment into epicardial adipose tissue (EAT) in patients with non-ST segment elevation myocardial infarction (NSTEMI) could be part of a specific antigen-driven response implicated in acute coronary syndrome onset and progression. Methods and Results: We enrolled 32 NSTEMI patients and 34 chronic coronary syndrome (CCS) patients undergoing coronary artery bypass grafting (CABG) and 12 mitral valve disease (MVD) patients undergoing surgery. We performed EAT proteome profiling on pooled specimens from three NSTEMI and three CCS patients. We performed T-cell receptor (TCR) spectratyping and CDR3 sequencing in EAT and peripheral blood mononuclear cells of 29 NSTEMI, 31 CCS, and 12 MVD patients. We then used computational modeling studies to predict interactions of the TCR beta chain variable region (TRBV) and explore sequence alignments. The EAT proteome profiling displayed a higher content of pro-inflammatory molecules (CD31, CHI3L1, CRP, EMPRINN, ENG, IL-17, IL-33, MMP-9, MPO, NGAL, RBP-4, RETN, VDB) in NSTEMI as compared to CCS (P < 0.0001). CDR3-beta spectratyping showed a TRBV21 enrichment in EAT of NSTEMI (12/29 patients; 41%) as compared with CCS (1/31 patients; 3%) and MVD (none) (ANOVA for trend P < 0.001). Of note, 11/12 (92%) NSTEMI patients with TRBV21 perturbation were at their first manifestation of ACS. Four patients with the first event shared a distinctive TRBV21-CDR3 sequence of 178 bp length and 2/4 were carriers of the human leukocyte antigen (HLA)-A*03:01 allele. A 3D analysis predicted the most likely epitope able to bind HLA-A3*01 and interact with the TRBV21-CDR3 sequence of 178 bp length, while the alignment results were consistent wit

Despite the recent innovations in cardiovascular care, atherothrombosis is still a major complication of acute coronary syndromes (ACS). We evaluated the involvement of the CD31 molecule in thrombotic risk through the formation of monocyte-platelet (Mo-Plt) aggregates in patients with ACS with no-ST-segment elevation myocardial infarction (NSTEMI) on top of dual anti-platelet therapy (DAPT). We enrolled 19 control (CTRL) subjects, 46 stable angina (SA), and 86 patients with NSTEMI, of which, 16 with Intact Fibrous Cap (IFC) and 19 with Ruptured Fibrous Cap (RFC) as assessed by the Optical Coherence Tomography (OCT). The expression of CD31 on monocytes and platelets was measured. Following the coronary angiography, 52 NSTEMIs were further stratified according to thrombus grade (TG) evaluation. Finally, a series of ex vivo experiments verified whether the CD31 participates in Mo-Plt aggregate formation. In patients with NSTEMI, CD31 was reduced on monocytes and was increased on platelets, especially in NSTEMI presented with RFC plaques compared to those with IFC lesions, and in patients with high TG compared to those with zero/low TG. Ex vivo experiments documented an increase in Mo-Plt aggregates among NSTEMI, which significantly decreased after the CD31 ligation, particularly in patients with RFC plaques. In NSTEMI, CD31 participates in Mo-Plt aggregate formation in spite of optimal therapy and DAPT, suggesting the existence of alternative thrombotic pathways, as predominantly displayed in patients with RFC.

Functional tricuspid valve regurgitation in the contest of mitral valve disease is a highly prevalent disease. We describe a ringless technique that combines restrictive annuloplasty (De Vega) with posterior tricuspid leaflet obliteration (Kay) used for patients with less-than-severe functional tricuspid valve regurgitation undergoing mitral valve surgery. The technique has been in use at our center since 2012, showing promising long-term echocardiographic results, with stable reduction of the annulus size and stable reduction of the degree of regurgitation.

Introduction: Left ventricular (LV) end-systolic elastance (Ees) can be estimated using single-beat (Ees(sb)) Chen method, employing systolic and diastolic arm-cuff pressures, stroke volume (SV), ejection fraction and estimated normalized ventricular elastance at arterial end-diastole. This work aims to conduct a sensitivity analysis of Chen formula to verify its reliability and applicability in clinical scenario. Methods: Starting from a baseline condition, we evaluated the sensitivity of Ees(sb) to the parameters contained in the formula. Moreover, a mathematical model of the cardiovascular system was used to evaluate the sensitivity of Ees(sb) to end-diastolic LV elastance (Eed), Ees, arterial systemic resistance (Ras) and heart rate (HR). Results: In accordance with Ees definition, Ees(sb) increases by increasing aortic pressure and pre-ejection time, reaching the highest value for a pre-ejection time = 40 ms, and then decreases. In contrast with Ees definition, Ees(sb) increases (from 3.21 mmHg/mL to 12.15 mmHg/mL) by increasing the LV end-systolic volume and decreases by increasing the SV. In the majority of the analysis with the mathematical model, Ees was underestimated using the Chen method: by increasing Ees (from 0.5 to 2.5 mmHg/mL), Ees(sb) passes only from 0.56 to 1.54 mmHg/mL. Ees(sb) increases for higher Eed (from 1.03 to 2.33 mmHg/mL). Finally, Ees(sb) decreases (increases) for HR < 50 bpm (< 50 bpm), and for Ras < 1100 mmHg/gcm4 (> 1100 mmHg/gcm4). Conclusion: Unexpectedly Ees(sb) increases for higher LV end-systolic volume and decreases for higher SV. These results contrast with Ees definition, which is the ratio between the LV end-systolic pressure and the LV end-systolic volume. Moreover, Ees(sb) is influenced by cardiocirculatory parameters such as LV Eed, HR, Ras, ejection time, and pre-ejection time. Finally, Ees(sb) computed with the model output often underestimates model Ees.

Few data are available on the prevalence of right ventricle (RV) systolic dysfunction, assessed including RV strain, and RV to pulmonary artery (PA) coupling in patients with aortic stenosis (AS) submitted to TAVI and the early effect of the procedure. We performed standard and speckle tracking echocardiography in 80 patients with severe AS the day before TAVI and within 48 h after TAVI. In all patients we measured TAPSE/PASP (cut-off for RV-PA uncoupling 0.31) and in 60/80 we were able to analyze RV global longitudinal strain (RV-GLS) and RV free wall strain (RV-FWS). RVFAC and TAPSE were impaired in 8.3% while RV-GLS and RV-FWS in 45% and 33.3% respectively before TAVI. TAPSE/PASP < 0.31 was documented in 7/80 patients (8.7%) before TAVI. These subjects differed from patients with TAPSE/PASP ≥ 0.31 for: enlarged left ventricular (LV) end-diastolic and end-systolic volumes (p < 0.001), worst LV ejection fraction (p < 0.001) and RVFAC (p < 0.001), worst RV-GLS and RV-FWS (p = 0.01 and p = 0.03) and bigger right atrium (RA) area (p < 0.001). After TAVI, RV systolic function did not improve while PASP significantly decreased (p = 0.005) driving the improvement of TAPSE/PASP (p = 0.01). Patients with TAPSE/PASP improvement (51%) differed from the others for worst pre-TAVI diastolic function (E/eʹ p = 0.045), RVFAC (p = 0.042), RV-GLS (p = 0.049) and RA area (p = 0.02). RV-GLS unveils RV systolic dysfunction in as much as 45% of patients with AS vs only 8.3% revealed by conventional echocardiography. RV systolic function does not significantly improve early after TAVI while RV-PA coupling does. Patients with lower TAPSE/PASP at baseline have worst LV and RV systolic function as well as larger RA. Patients who improve TAPSE/PASP after TAVI are those with worst diastolic function, RV systolic function and larger RA at baseline.

AIM: To summarize our experience on the implementation of a telemedicine service dedicated to adult congenital heart disease (ACHD) patients during the lockdown for the first wave of Coronavirus disease 2019 (COVID-19). METHODS: This is a prospective study enrolling all ACHD patients who answered a questionnaire dedicated telematic cardiovascular examination. RESULTS: A total of 289 patients were enrolled, 133 (47%) were male, 25 (9%) were affected by a genetic syndrome. The median age was 38 (29-51) years, whereas the median time interval between the last visit and the telematic follow-up was 9.5 (7.5-11.5) months. Overall, 35 patients (12%) reported a worsening of fatigue in daily life activity, 17 (6%) experienced chest pain, 42 (15%) had presyncope and 2 (1%) syncope; in addition, 28 patients (10%) presented peripheral edema and 14 (5%) were orthopneic. A total of 116 (40%) patients reported palpitations and 12 had at least one episode of atrial fibrillation and underwent successful electrical (8) or pharmacological (4) cardioversion. One patient was admitted to the emergency department for uncontrolled arterial hypertension, five for chest pain, and one for heart failure. Two patients presented fever but both had negative COVID-19 nasal swab. CONCLUSION: During the COVID-19 pandemic, the use of telemedicine dramatically increased and here we report a positive experience in ACHD patients. The postpandemic role of telemedicine will depend on permanent regulatory solutions and this early study might encourage a more systematic telematic approach for ACHD patients.

Background: Sleep apnea syndrome (SAS) has been reported to be associated with a higher incidence of ventricular arrhythmias. The aim of this study was twofold: (1) to investigate whether in SAS patients receiving an implantable cardioverter defibrillator (ICD) the severity of SAS was associated with the occurrence of ventricular arrhythmias; (2) to assess whether changes in nocturnal apnoic/hypopnoic episodes may favor the occurrence of life-threatening arrhythmias, that is, sustained ventricular tachycardia (VT)/fibrillation (VF), requiring ICD intervention. Methods: We enrolled 46 patients with documented SAS at polysomnography (apnea/hypopnea index [AHI] > 5) who also had a left ventricle ejection fraction (LVEF) < 35% and, according to primary prevention indications, implanted an ICD (Boston Scientific Incepta) able to daily monitor apnoic/hypopnoic episodes occurring during sleep. Patients were followed at 3-month intervals. Results: At a mean follow-up of 18 months, 21 episodes of sustained VT/FV requiring ICD intervention were documented in eight patients (17.4%). Baseline AHI was significantly higher in patients with compared to those without ICD intervention. ICD interventions, however, were not preceded by any worsening of apnoic/hypopnoic episodes. The respiratory disturbance index (RDI) of the week during the event, indeed, was not different from that recorded during the previous 2 weeks (25.4 ± 11, 25.6 ± 10 and 25.1 ± 10, respectively; p =.9). Conclusions: In patients with SAS who received an ICD for primary prevention of sudden death, those with ICD interventions showed a more severe form of the disease at baseline. ICD interventions, however, were not preceded by any significant changes in SAS severity.

Amiodarone is a drug commonly used to treat and prevent cardiac arrhythmias, but it is often associated with several adverse effects, the most serious of which is pulmonary toxicity. A 79-year-old man presented with respiratory failure due to interstitial pneumonia during the COVID-19 pandemic. The viral etiology was nevertheless excluded by repeated nasopharyngeal swabs and serological tests and the final diagnosis was amiodarone-induced organizing pneumonia. The clinical and computed tomography findings improved after amiodarone interruption and steroid therapy. Even during a pandemic, differential diagnosis should always be considered and pulmonary toxicity has to be taken into account in any patient taking amiodarone and who has new respiratory symptoms.

Background: Atrial fibrillation is the most common complication after cardiac surgery and is associated with extended in-hospital stay and increased adverse outcomes, including death and stroke. Pericardial effusion is common after cardiac surgery and can trigger atrial fibrillation. We tested the hypothesis that posterior left pericardiotomy, a surgical manoeuvre that drains the pericardial space into the left pleural cavity, might reduce the incidence of atrial fibrillation after cardiac surgery. Methods: In this adaptive, randomised, controlled trial, we recruited adult patients (aged ≥18 years) undergoing elective interventions on the coronary arteries, aortic valve, or ascending aorta, or a combination of these, performed by members of the Department of Cardiothoracic Surgery from Weill Cornell Medicine at the New York Presbyterian Hospital in New York, NY, USA. Patients were eligible if they had no history of atrial fibrillation or other arrhythmias or contraindications to the experimental intervention. Eligible patients were randomly assigned (1:1), stratified by CHA2DS2-VASc score and using a mixed-block randomisation approach (block sizes of 4, 6, and 8), to posterior left pericardiotomy or no intervention. Patients and assessors were blinded to treatment assignment. Patients were followed up until 30 days after hospital discharge. The primary outcome was the incidence of atrial fibrillation during postoperative in-hospital stay, which was assessed in the intention-to-treat (ITT) population. Safety was assessed in the as-treated population. This study is registered with ClinicalTrials.gov, NCT02875405, and is now complete. Findings: Between Sept 18, 2017, and Aug 2, 2021, 3601 patients were screened and 420 were included and randomly assigned to the posterior left pericardiotomy group (n=212) or the no intervention group (n=208; ITT population). The median age was 61·0 years (IQR 53·0–70·0), 102 (24%) patients were female, and 318 (76%) were male, with a me

Introduction: Multiple Myeloma (MM) is hematological neoplasia originating from plasma cells, which accounts for almost 1% of all oncologic malignancies. The median age of patients at diagnosis is about 65 years old and over. In this age group, cardiovascular (CV) diseases often co-exist, increasing the risk of adverse events related to MM treatment. A comprehensive search on the main educational platforms was performed and high-quality original articles and reviews were included. Areas Covered: Patients affected by MM are at risk for heart failure, uncontrolled systemic hypertension, accelerated ischemic heart disease, arterial/venous thromboembolism, and arrhythmias. These complications may be due to the effects of chemotherapy on the CV system, which may play on preexisting risk factors, and amyloid deposition at cardiac level. Expert Opinion: This review provides an updated overview of the spectrum of CV diseases that may affect MM patients, highlighting possible treatment strategies according to the latest recommendations. Cooperation between onco-hematologist and cardiologist is crucial in managing this population, in particular for adequate risk assessment, early diagnosis of CV complications, and proper treatment.

Overall, 35 patients (12%) reported a worsening of fatigue in daily life activity, 17 (6%) experienced chest pain, 42 (15%) had presyncope and 2 (1%) syncope; in addition, 28 patients (10%) presented peripheral edema and 14 (5%) were orthopneic. A total of 116 (40%) patients reported palpitations and 12 had at least one episode of atrial fibrillation and underwent successful electrical (8) or pharmacological (4) cardioversion. One patient was admitted to the emergency department for uncontrolled arterial hypertension, five for chest pain, and one for heart failure. Two patients presented fever but both had negative COVID-19 nasal swab. CONCLUSION: During the COVID-19 pandemic, the use of telemedicine dramatically increased and here we report a positive experience in ACHD patients. The postpandemic role of telemedicine will depend on permanent regulatory solutions and this early study might encourage a more systematic telematic approach for ACHD patients.

Background. The COVID-19 pandemic has had a deep impact on periodic outpatient evaluations. The aim of this study was to evaluate the impact of low brain natriuretic peptide (BNP) values in predicting adverse events in heart failure (HF) patients in order to evaluate implications for safe delay of outpatient visits. Methods. This was a retrospective study. One-thousand patients (mean age: 72 ± 10 years, 561 women) with HF and BNP values <250 pg/mL at discharge were included. A 6-month follow-up was performed. The primary endpoint was a combination of deaths and readmissions for HF within 6-month after discharge. Results. At 6-month follow-up, 104 events (10.4%) were recorded (65 HF readmissions and 39 all-cause deaths). Univariate Cox analysis identified as significant predictors of outcome were age (p < 0.001, hazard ratio [HR] = 1.044), creatinine (p = 0.001, HR = 1.411), and BNP (p < 0.001, HR = 1.010). Multivariate Cox regression confirmed that BNP (p < 0.001, HR = 1.009), creatinine (p = 0.016, HR = 1.247), and age (p = 0.013, HR = 1.027) were independent predictors of events in HF patients with BNP values <250 pg/mL at discharge. Patients with BNP values >100 pg/mL and creatinine >1.0 mg/dL showed increased events rates (from 4.3% to 19.0%) as compared to those with lower values (p < 0.000, HR = 4.014). Conclusions. Low pre-discharge BNP levels were associated with low rates of cardiovascular events in HF patients, independently of the frequency of follow-up.

Introduction: The association between thrombosis, cancer and inflammation is well-established. Platelets play a major role in atherosclerosis, inflammation and immune response. Furthermore, growing evidence suggests that they are also significantly involved in tumor development and progression so that anti-platelet agents may prevent cancer and improve outcomes in oncological patients. In this review, we aimed at analyzing the relationship between platelets, cardiovascular diseases and cancer. A comprehensive study in the main educational platforms was performed and high-quality original articles and reviews were included. Areas covered: This review will focus on the role of platelets in cardiovascular disease and in cancer genesis and progression, analyzing their function as immune cells that link inflammation to thrombosis. Finally, it will examine the recent controversies on the use of anti-platelet agents as cancer medications, in particular the already known anti-tumor properties of aspirin, as well as the new perspectives regarding P2Y12 inhibitors. Expert opinion: Platelet-cancer crosstalk generates a vicious feed-back loop involving tumor cells and secreting molecules that activate platelets, which in turn promote cancer-associated inflammation, proliferation, spreading and immune system evasion. Therefore, platelets inhibition may represent an innovative therapeutical strategy offered to cancer patients, in the perspective of personalized medicine.

Aim of this retrospective, multicenter study was to evaluate early and mid-term clinical and hemodynamic results of patients who underwent surgical aortic valve replacement (SAVR) with Intuity rapid-deployment bioprostheses (RDB) (Edwards Lifesciences, Irvine, CA). We analyzed data from the Italian Registry of Intuity Valve (INTU-ITA registry) that is a national, real-world and independent from the industry registry. Preoperative variables were defined according to EuroSCORE and postoperative outcomes according to Valve Academic Research Consortium (VARC). Survival distribution was evaluated using the Kaplan-Meier approach. A Cox-Proportional Hazard Model was employed to assess the effect of the covariates on patients’ survival. The registry included 1687 patients from 23 centers (June 2012-September 2019). Aortic cross clamp time for isolated SAVR was 55 minutes (IQR: 45–70 minute). Postoperative pace-maker rate was 6.3%. At discharge transaortic peak and mean gradients were: 18 mm Hg (IQR: 14–23 mm Hg) and 10 mmHg (IQR: 8–13 mm Hg), respectively. Indexed effective orifice area was 1.10 cm2/m2 (IQR: 0.91–1.31 cm2/m2) and the incidence of severe patient-prosthesis mismatch was 0.6%. Hemodynamic data for all valve sizes remained stable during follow-up. Thirty-day overall mortality was 1.8% (30 patients), and at follow-up it was 5.3% (89 patients). Kaplan-Meier overall survival was 95.5% (94.3–96.7%); 90.7% (88.3–93.1%); 86.4% (82.6–90.4%) at 1, 3, and 5 years, respectively. Serum creatinine (HR: 1.36; 95%CI: 1.04–1.81; p = 0.0397) and cross-clamp time (HR: 1.01; 95%CI: 1.002–1.017; p = 0.0077) were identified as independent predictors of mortality. According to our data from the INTU-ITA registry, SAVR with RDB provides good early clinical and hemodynamic results that are confirmed at follow-up.

Background. A prothrombotic state, attributable to excessive inflammation, cytokine storm, hypoxia, and immobilization, is a feature of SARS-CoV-2 infection. Up to 30% of patients with severe COVID-19 remain at high risk of thromboembolic events despite anticoagulant administration, with adverse impact on in-hospital prognosis. Methods. We retrospectively studied 4742 patients with acute infectious respiratory disease (AIRD); 2579 were diagnosed to have COVID-19 and treated with heparin, whereas 2163 had other causes of AIRD. We compared the incidence and predictors of total, arterial, and venous thrombosis, both in the whole population and in a propensity score-matched subpopulation of 3036 patients (1518 in each group). Results. 271 thrombotic events occurred in the whole population: 121 (4.7%) in the COVID-19 group and 150 (6.9%) in the no-COVID-19 group (p < 0.001). No differences in the incidence of total (p = 0.11), arterial (p = 0.26), and venous (p = 0.38) thrombosis were found between the two groups after adjustment for confounding clinical variables and in the propensity score-matched subpopulation. Likewise, there were no significant differences in bleeding rates between the two groups. Clinical predictors of arterial thrombosis included age (p = 0.006), diabetes mellitus (p = 0.034), peripheral artery disease (p < 0.001), and previous stroke (p < 0.001), whereas history of solid cancer (p < 0.001) and previous deep vein thrombosis (p = 0.007) were associated with higher incidence of venous thrombosis. Conclusions. Hospitalized patients with COVID-19 treated with heparin do not seem to show significant differences in the cumulative incidence of thromboembolic events as well as in the incidence of arterial and venous thrombosis separately, compared with AIRD patients with different etiological diagnosis.

OBJECTIVES: Healthcare systems worldwide have been overburdened by the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, hospitals had to implement strategies to profoundly reshape both non-COVID-19 medical care and surgical activities. Knowledge about the impact of the COVID-19 pandemic on cardiac surgery practice is pivotal. The goal of the present study was to describe the changes in cardiac surgery practices during the health emergency at the national level. METHODS: A 26-question web-enabled survey including all adult cardiac surgery units in Italy was conducted to assess how their clinical practice changed during the national lockdown. Data were compared to data from the corresponding period in 2019. RESULTS: All but 2 centres (94.9%) adopted specific protocols to screen patients and personnel. A significant reduction in the number of dedicated cardiac intensive care unit beds (-35.4%) and operating rooms (-29.2%), along with healthcare personnel reallocation to COVID departments (nurses-15.4%, anaesthesiologists-7.7%), was noted. Overall adult cardiac surgery volumes were dramatically reduced (1734 procedures vs 3447; P 0.001), with a significant drop in elective procedures [580 (33.4%) vs 2420 (70.2%)]. CONCLUSIONS: This national survey found major changes in cardiac surgery practice as a response to the COVID-19 pandemic. This experience should lead to the development of permanent systems-based plans to face possible future pandemics. These data may effectively help policy decision-making in prioritizing healthcare resource reallocation during the ongoing pandemic and once the healthcare emergency is over. © 2021 The Author(s).

Introduction: Minimally invasive aortic valve replacement (MIAVR) requires changes in cannulation strategy and cardiopulmonary bypass (CPB) management when compared to the conventional approach (CAVR). We aimed at evaluating if these differences could influence perfusion-related quality parameters and impair postoperative outcomes. Methods: Overall, 339 consecutive patients underwent MIAVR or CAVR between 2014 and 2020 and were analyzed retrospectively. To account for baseline differences, a propensity-matching analysis was performed, obtaining two groups of 97 patients each. Results: MIAVR group had longer CPB time [107 (95–120) vs 95 (86–105) min, p =.003] than CAVR group. Of note, average pump flow rate index [2.4 (2.2–2.5) vs 2.7 (2.4–2.8) l/min/m2, p =.004] was lower in the MIAVR group. Mean arterial pressure was 73 = 9 mmHg vs 62 = 11 mmHg for the MIAVR and CAVR group, respectively (p <.001). Cell-salvaged blood was most commonly used in the MIAVR group (25.8% vs 11.3%, p =.02). Finally, CPB temperature was 32.8°C (32.1–34.8) for MIAVR group vs 34.9°C (33.2–36.1) for the CAVR group (p =.02). Postoperative complications were similar between groups. Conclusions: In conclusion, despite differences in CPB parameters in patients undergoing CAVR and MIAVR, the incidences of adverse outcomes were similar. However, compared to CAVR, MIAVR was associated with shorter durations of mechanical ventilation and hospital stay as well as less transfusion of blood products.

Background and aims: The increasing prevalence of diabetes mellitus is causing a massive growth of peripheral artery disease incidences, a disabling complication of diabetic atherosclerosis, which leads often to the amputation of the affected limb. Critical limb ischemia is the terminal disease stage, which requires a prompt intervention to relieve pain and save limbs. However, patients undergoing revascularization often suffer from cardiovascular, cerebrovascular and major adverse limb events with poor outcomes. Furthermore, the same procedure performed in apparently similar patients has various outcomes and lack of an outcome predictive support causes a high lower limb arterial revascularization rate with disastrous effects for patients. We collected the main risk factors of major adverse limb events in a more readable and immediate format of the topic, to propose an overview of parameters to manage effectively peripheral artery disease patients and to propose basics of a new predictive tool to prevent from disabling vascular complications of the disease. Methods: Most recent and updated literature about the prevalence of major adverse limb events in peripheral artery disease was reviewed to identify possible main predictors. Results: In this article, we summarized major risk factors of limb revascularization failure and disabling vascular complications collecting those parameters principally responsible for major adverse limb events, which provides physio-pathological explanation of their role in peripheral artery disease. Conclusion: We evaluated and listed a panel of possible predictors of MALE (Major Adverse Limb Event) in order to contribute to the development of a predictive score, based on a summary of the main risk factors reported in scientific articles, which could improve the management of peripheral artery disease by preventing vascular accidents.

Background: The aim of this multicenter retrospective study was to compare early and midterm clinical and hemodynamic results of aortic valve replacement with rapid-deployment bioprostheses performed through conventional full-sternotomy vs mini-sternotomy. Methods: Data from the Italian multicenter registry of aortic valve replacement with rapid-deployment bioprostheses (INTU-ITA registry) were analyzed. Patients were divided into 2 groups: full sternotomy (FS) and ministernotomy (MS). Primary endpoint was the comparison of early and midterm mortality. Secondary endpoints were: comparison of intraoperative variables, complications, and hemodynamic performance. A propensity score weighting approach was used for data analysis. Results: A total of 1057 patients were analyzed: 435 (41.2%) and 622 (58.8%) in group FS and MS, respectively. Thirty-day mortality was 1.6% and 0.6% in FS and MS groups, respectively (P =.074). cardiopulmonary bypass time was 78.5 minutes and 83 minutes in FS and MS groups, respectively (P =.414). In the overall cohort, the incidence of intraoperative complications and of device success was 3.8% (40 patients) and 95.9% (1014 patients), respectively, with no significant differences between groups. Survival at 1, 3, and 5 years was 94.1%, 98.1%, 88.5% and 91.8%, 85.2%, and 84.8% in FS and MS groups, respectively (P =.412). The 2 groups showed similar postoperative gradients (median mean gradient, FS: 10.0 mm Hg, MS: 11.0 mm Hg; P =.170) and also similar incidence of patient–prosthesis mismatch (FS: 7%, MS: 6.4%, P =.647). Conclusions: According to our data, rapid-deployment bioprostheses allow the performance of minimally invasive aortic valve replacement with similar surgical times and similar clinical and hemodynamic outcomes to conventional surgery and should be considered the first choice in these procedures.

Atherosclerotic plaque instability and rupture in patients with asymptomatic carotid artery stenosis (ACAS) is a leading cause of major adverse cardiac events (MACE). This could be mainly evidenced in patients with pre-diabetes. Indeed, the altered glucose homeostasis and insulin resistance could cause over-inflammation of atherosclerotic plaque, favoring its conversion to unstable phenotype with rupture and MACE. Notably, metformin therapy reducing the metabolic distress and the inflammatory burden could reduce MACE in ACAS patients with pre-diabetes. In this setting, the microRNAs (miRs) could be used as molecular biomarkers of atherosclerosis progression, plaque rupture, and worse prognosis in normoglycemics (NG) versus pre-diabetics metformin users (PDMU) versus pre-diabetics non-metformin users (PDNMU). However, our study aimed to investigate a wide miRNA panel in peripheral blood exosomes from patients with ACAS divided in NG versus PDMU versus PDNMU, and to associate the circulating miRNA expression profiles with MACE at 2 years of follow-up after endarterectomy. The study included 234 patients with ACAS divided into NG (n = 125), PDNMU (n = 73), and PDMU (n = 36). The miRs’ expression profiles of circulating exosomes were determined at baseline and at 2 years of follow-up by Affymetrix microarrays from the patients’ plasma samples from any study cohort. Then we collected and analyzed MACE at 2 years of follow-up in NG versus PDMU versus PDNMU. Prediabetics versus NG had over-inflammation (p < 0.05) and over expressed miR-24 and miR-27 at baseline. At 2 years of follow-up, PDNMU versus NG, PDMU versus NG, and PDNMU versus PDMU over-expressed inflammatory markers and miR-24, miR-27, miR-100, miR-126, and miR-133 (p < 0.05). Finally, at the end of follow-up, we observed a significant difference about MACE comparing PDNMU versus NG (n = 27 (36.9%) versus n = 8 (6.4%); p < 0.05), PDNMU versus PDMU (n = 27 (36.9%) versus n = 6 (16.6%); p < 0.05); and P

Background: Carotid atherosclerosis represents one of the complications of diabetes mellitus. In particular, plaque instability contributes to disease progression and stroke incidence. High mobility group box-1 (HMGB1) is a nuclear protein involved in promotion and progression of atherosclerosis and cardiovascular diseases. The aim of this study was to analyze the relationship between HMGB1 serum levels, main inflammatory cytokines, the presence of internal carotid stenosis and unstable plaque in a diabetic population. Research design and methods: We studied 873 diabetic patients, including 347 patients with internal carotid artery stenosis (ICAS) who underwent carotid endarterectomy and 526 diabetic patients without internal carotid artery stenosis (WICAS). At baseline, HMGB1 and the main inflammatory cytokines serum levels were evaluated. For ICAS patients, the histological features of carotid plaque were also collected to differentiate them in patients with stable or unstable atherosclerotic lesions. Results: We found that HMGB1 serum levels, osteoprotegerin, high-sensitivity C-reactive protein, tumor necrosis factor-alpha and interleukin-6, were significantly higher in diabetic ICAS patients compared to diabetic WICAS patients. Among ICAS patients, individuals with unstable plaque had higher levels of these cytokines, compared to patients with stable plaque. A multivariable stepwise logistic regression analysis showed that HMGB1 and osteoprotegerin remained independently associated with unstable plaque in ICAS patients. Conclusions: The present study demonstrated that HMGB1 is an independent risk factor for carotid plaque vulnerability in an Italian population with diabetes mellitus, representing a promising biomarker of carotid plaque instability and a possible molecular target to treat unstable carotid plaques and to prevent stroke.

The SARS-CoV-2 infection determines the COVID-19 syndrome characterized, in the worst cases, by severe respiratory distress, pulmonary and cardiac fibrosis, inflammatory cytokine release, and immunosuppression. This condition has led to the death of about 2.15% of the total infected world population so far. Among survivors, the presence of the so-called persistent post-COVID-19 syndrome (PPCS) is a common finding. In COVID-19 survivors, PPCS presents one or more symptoms: fatigue, dyspnea, memory loss, sleep disorders, and difficulty concentrating. In this study, a cohort of 117 COVID-19 survivors (post-COVID-19) and 144 non-infected volunteers (COVID-19-free) was analyzed using pyrosequencing of defined CpG islands previously identified as suitable for biological age determination. The results show a consistent biological age increase in the post-COVID-19 population, determining a DeltaAge acceleration of 10.45 ± 7.29 years (+5.25 years above the range of normality) compared with 3.68 ± 8.17 years for the COVID-19-free population (p < 0.0001). A significant telomere shortening parallels this finding in the post-COVID-19 cohort compared with COVID-19-free subjects (p < 0.0001). Additionally, ACE2 expression was decreased in post-COVID-19 patients, compared with the COVID-19-free population, while DPP-4 did not change. In light of these observations, we hypothesize that some epigenetic alterations are associated with the post-COVID-19 condition, particularly in younger patients (<60 years).

– OBJECTIVE: Ventricular septal defect (VSD) is an uncommon but frequently fatal complication following acute myocardial infarction. In medically treated patients, mortality rates exceed 90%, while the surgical repair is associated with better outcomes, even though optimal surgical timing is still under debate. CASE REPORT: We present the case of a 78-years-old man with no previous remarkable cardiological history admitted to our Emergency Department with the diagnosis of anteri- or ST-elevation myocardial infarction and significant reduction of left ventricular ejection fraction. The emergency coronary angiography showed sub-occlusion of the left anterior descending coronary artery, treated with stent implantation. The post-procedural echocardiography unveiled the presence of an apical VSD with a large left-to-right shunt, significant right ventricular overload and dysfunction. An intra-aortic balloon pump (IABP) was positioned and, after Heart Team evaluation, a delayed surgical approach was planned. As a bridge to the intervention Levosimendan infusion was administered, on top of IABP support, and a significant improvement in bi-ventricular function and pressure profiles was obtained. Cardiac surgery was successfully performed 9 days after the admission without periprocedural complications. CONCLUSIONS: This unique case supports the use of Levosimendan as a valid pharmacological strategy for perioperative management of VSD.

Valvular heart diseases (VHD) are common in the elderly population and several therapeutic options are available to treat them. When selecting the management strategy for VHD patients, to evaluate the operatory risk, using special scores like STS score, EuroSCORE II and other more specific ones is pivotal. However, the risk scores do not consider some aspects, such as the clinical needs of the single patients, the management of local resources and the expertise of the center. The Heart Team, combining the experience of various specialists, can optimize the decision-making process through a better evaluation of the risk/benefit ratio of the therapeutic choices. The multidisciplinary discussion of the most complex cases is recommended by the international guidelines for the management of VHD and it is part of the clinical practice of many centers. So far, both trials and large clinical studies supporting such multidisciplinary management are lacking. Despite these important limitations, the Heart Team can be actually regarded as a promising tool to locally promote best practices for the treatment of VHD patients.

Acute Coronary Syndromes (ACS) with plaque erosion display dysregulated hyaluronan metabolism, with increased hyaluronidase-2 (HYAL2) expression. However, the expression and the role of this enzyme on platelets has never been explored. We evaluated the platelet’s HYAL2 (pltHYAL2) levels on I) stable angina (SA) and II) ACS patients, furtherly sub-grouped in Intact-Fibrous-Cap (IFC) and Ruptured-Fibrous-Cap (RFC), according to Optical Coherence Tomography. We assessed the HYAL2 role through an in vitro model setting of co-cultured monocytes and platelets, before and after treatment with low-molecular-weight hyaluronic acid (HA) as pro-inflammatory stimulus and with or without HYAL2-antibody to inhibit HYAL2 activity. ACS patients exhibit higher pltHYAL2 levels comparing to SA, with the higher expression for IFC group. The addition of HYAL2-antibody significantly reduced the percentage of monocyte-platelet binding, suggesting that pltHYAL2 enrichment at the site of the culprit lesion is a key mediator in the systemic thrombo-inflammatory status of ACS presenting with plaque erosion.

Mitral valve repair is typically performed by implanting a ring-like device at the valve annulus to reshape the annulus and to improve leaflet coaptation. In most cases, some additional procedures are needed, including leaflet resection and artificial chordae implantation. However, artificial chordae implantation could be technically challenging and postoperative left ventricular remodeling could increase the risk of recurrent mitral regurgitation. We propose an innovative annular device made of chromo-cobalt, finalized not only to reshape the annulus but also to enable anchoring of leaflets to a fixed intraventricular structure. Durability evaluation of the device was tested by applying eight radial force vectors equally spaced along the ring and related fatigue analysis. To evaluate the efficacy of the mitral valvuloplasty using the tested ring, the device was implanted in five adult swine hearts. Functional analysis of the ring was performed by measuring left ventricular pressure and fluid volume loss, following implantation in normal and dysfunctional mitral valve leaflets. Both fatigue and functional analysis showed satisfactory and promising results in terms of durability and efficacy of mitral valve repair. Because of its favorable durability and functional characteristics this device appears promising and provides good results in terms of valve competence, thus avoiding both manipulations of papillary muscles and interference in left ventricular hemodynamics. However, an in vivo test is mandatory to fully understand the impact of the device on subvalvular apparatus.

Heart failure is the cardiovascular epidemic of the 21st century, with poor prognosis and quality of life despite optimized medical treatment. In the past two decades, only two new drugs have been added to therapeutic strategies for patients with symptomatic heart failure and even less progresses have been made on devices, with the implantable defibrillator indicated for patients with ejection fraction ≤35% and cardiac resynchronization therapy for those with QRS >130 ms and evidence of left bundle branch block. Nevertheless, only a third of patients meet these criteria and a high percentage of patients are non-responders in terms of improving symptoms. Nowadays, in patients with symptomatic heart failure with ejection fraction between 25% and 45% and QRS <130 ms, not eligible for cardiac resynchronization therapy, cardiac contractility modulation represents a concrete treatment option, having proved to be safe and effective in reducing hospitalizations for heart failure and improving symptoms, functional capacity and quality of life.The aim of this review is therefore to summarize the pathophysiological mechanisms, the current indications and the recent developments regarding the new applications of cardiac contractility modulation for patients with chronic heart failure.

Refractory cardiogenic shock (RCS) or refractory cardiac arrest (RCA) complicating acute coronary syndrome (ACS) is associated with extremely high mortality rate. Veno-arterial extracorporeal life support (VA-ECLS) represents a valuable therapeutic option to stabilize patients’ condition before or at the time of emergency revascularization. We analyzed 29 consecutive patients with RCS or RCA complicating ACS, and implanted with VA-ECLS in two centers who have adopted a similar, structured approach to ECLS implantation. Data were collected from January 2010 to December 2015 and ECLS had to be percutaneously implanted either before (within 48 h) or at the time of attempted percutaneous coronary revascularization (PCI). We investigated in-hospital outcome and factors associated with survival. Twenty-one (72%) were implanted for RCA, whereas 8 (28%) were implanted on ECLS for RCS. All RCA were witnessed and no-flow time was shorter than 5 min in all cases but one. All patients underwent attempted emergency PCI, using radial access in ten cases (34.5%), whereas in three patients a subsequent CABG was performed. Overall, ten patients (34.5%) survived, nine of them with a good neurological outcome. Life threatening complications, including stroke (4 pts), leg ischemia (4 pts), intestinal ischemia (5 pts), and deep vein thrombosis 2 pts), occurred frequently, but were not associated with in-hospital death. Main cause of death was multi-organ failure. PCI variables did not predict survival. Survivors were younger, with shorter low-flow time, and with ECLS mainly implanted for RCS. At multivariate analysis, levels of lactate at ECLS implantation (OR 4.32, 95%CI 1.01–18.51, p = 0.049) emerged as the only variable that independently predicted survival. In patients with RCA or RCS complicating ACS who are percutaneously implanted with ECLS before or at the time of coronary revascularization, in hospital survival rate is higher than 30%. Level of lactate at ECLS im

Objective: Aortic valve disease is more and more common in western countries. While percutaneous approaches should be preferred in older adults, previous reports have shown good outcomes after surgery. Moreover, advantages of minimally invasive approaches may be valuable for octogenarians. We sought to compare outcomes of conventional aortic valve replacement (CAVR) versus minimally invasive aortic valve replacement (MIAVR) in octogenarians. Methods: We retrospectively collected data of 75 consecutive octogenarians who underwent primary, elective, isolated aortic valve surgery through conventional approach (41 patients, group CAVR) or partial upper sternotomy (34 patients, group MIAVR). Results: Mean age was 81.9 ± 0.9 and 82.3 ± 1.1 years in CAVR and MIAVR patients, respectively (P = 0.09). MIAVR patients had lower 24-hour chest drain output (353.4 ± 207.1 vs 501.7 ± 229.9 mL, P < 0.01), shorter mechanical ventilation (9.6 ± 2.4 vs 11.3 ± 2.3 hours, P < 0.01), lower need for blood transfusions (35.3% vs 63.4%, P = 0.02), and shorter hospital stay (6.8 ± 1.6 vs 8.3 ± 4.3 days, P < 0.01). Thirty-day mortality was zero in both groups. Survival at 1, 3, and 5 years was 89.9%, 80%, and 47%, respectively, in the CAVR group, and 93.2%, 82.4%, and 61.8% in the MIAVR group, with no statistically significant differences (log-rank test, P = 0.35). Conclusions: Aortic valve surgery in older patients provided excellent results, as long as appropriate candidates were selected. MIAVR was associated with shorter mechanical ventilation, reduced blood transfusions, and reduced hospitalization length, without affecting perioperative complications or mid-term survival.

Thoracic endovascular aortic repair (TEVAR) is a life-saving treatment for blunt thoracic aortic injury. We report long-term outcomes of two young patients who underwent TEVAR for blunt thoracic aortic injury with first-generation thoracic stent grafts. The off-label use of the endograft affected the outcomes: one case of open surgery conversion due to an aortoesophageal fistula and one case of endovascular relining for a voluminous pseudoaneurysm associated with a type III endoleak. Long-term follow-up is crucial in TEVAR, especially in case of a first-generation device used in an urgent setting.

Many European countries have responded to the COVID-19 pandemic by implementing nationwide protection measures and lockdowns1. However, the epidemic could rebound when such measures are relaxed, possibly leading to a requirement for a second or more, repeated lockdowns2. Here, we present results of a stochastic agent-based microsimulation model of the COVID-19 epidemic in France. We examined the potential impact of post-lockdown measures, including physical distancing, mask-wearing and shielding individuals who are the most vulnerable to severe COVID-19 infection, on cumulative disease incidence and mortality, and on intensive care unit (ICU)-bed occupancy. While lockdown is effective in containing the viral spread, once lifted, regardless of duration, it would be unlikely to prevent a rebound. Both physical distancing and mask-wearing, although effective in slowing the epidemic and in reducing mortality, would also be ineffective in ultimately preventing ICUs from becoming overwhelmed and a subsequent second lockdown. However, these measures coupled with the shielding of vulnerable people would be associated with better outcomes, including lower mortality and maintaining an adequate ICU capacity to prevent a second lockdown. Benefits would nonetheless be markedly reduced if most people do not adhere to these measures, or if they are not maintained for a sufficiently long period.

Secondary mitral insufficiency (SMI) is caused by dilatation and left ventricular dysfunction and is a frequent finding in patients with heart failure (HF). It is associated with a mortality of between 40% and 50% at 3 years. The first-line treatment is represented by medical therapy, possibly associated, when indicated, with cardiac resynchronization. If the patient remains symptomatic, corrective action should be considered. Surgery is indicated in cases of severe SMI with ejection fraction >30% and the need for myocardial revascularization. The management of patients in whom revascularization is not an option remains extremely complex and the evidence in this field is extremely limited. Percutaneous transcatheter therapies, reparative or replacement, are rapidly emerging as valid alternatives in cases of patients at high surgical risk. In particular, edge-to-edge repair (MitraClip) has proven effective in improving symptoms and reducing hospitalizations for HF. However, neither transcatheter nor surgical mitral repair or replacement has been shown to significantly improve prognosis, with mortality remaining high (14-20% at 1 year). Randomized trials aimed at assessing the effect of these treatments and establishing their long-term outcomes are urgently required.

Refractory cardiogenic shock (RCS) or refractory cardiac arrest (RCA) complicating acute coronary syndrome (ACS) is associated with extremely high mortality rate. Veno-arterial extracorporeal life support (VA-ECLS) represents a valuable therapeutic option to stabilize patients’ condition before or at the time of emergency revascularization. We analyzed 29 consecutive patients with RCS or RCA complicating ACS, and implanted with VA-ECLS in two centers who have adopted a similar, structured approach to ECLS implantation. Data were collected from January 2010 to December 2015 and ECLS had to be percutaneously implanted either before (within 48 h) or at the time of attempted percutaneous coronary revascularization (PCI). We investigated in-hospital outcome and factors associated with survival. Twenty-one (72%) were implanted for RCA, whereas 8 (28%) were implanted on ECLS for RCS. All RCA were witnessed and no-flow time was shorter than 5 min in all cases but one. All patients underwent attempted emergency PCI, using radial access in ten cases (34.5%), whereas in three patients a subsequent CABG was performed. Overall, ten patients (34.5%) survived, nine of them with a good neurological outcome. Life threatening complications, including stroke (4 pts), leg ischemia (4 pts), intestinal ischemia (5 pts), and deep vein thrombosis 2 pts), occurred frequently, but were not associated with in-hospital death. Main cause of death was multi-organ failure. PCI variables did not predict survival. Survivors were younger, with shorter low-flow time, and with ECLS mainly implanted for RCS. At multivariate analysis, levels of lactate at ECLS implantation (OR 4.32, 95%CI 1.01–18.51, p = 0.049) emerged as the only variable that independently predicted survival. In patients with RCA or RCS complicating ACS who are percutaneously implanted with ECLS before or at the time of coronary revascularization, in hospital survival rate is higher than 30%. Level of lactate at ECLS im

Objectives: To evaluate the effects of cardiac resynchronization therapy (CRTd) in patients with type 2 diabetes mellitus (T2DM) optimized via automatic vs. echocardiography-guided approach. Background: The suboptimal atrio-ventricular (AV) and inter-ventricular (VV) delays optimization reduces CRTd response. Therefore, we hypothesized that automatic CRTd optimization might improve clinical outcomes in T2DM patients. Methods: We designed a prospective, multicenter study to recruit, from October 2016 to June 2019, 191 consecutive failing heart patients with T2DM, and candidate to receive a CRTd. Study outcomes were CRTd responders rate, hospitalizations for heart failure (HF) worsening, cardiac deaths and all cause of deaths in T2DM patients treated with CRTd and randomly optimized via automatic (n 93) vs. echocardiography-guided (n 98) approach at 12 months of follow-up. Results: We had a significant difference in the rate of CRTd responders (68 (73.1%) vs. 58 (59.2%), p 0.038), and hospitalizations for HF worsening (12 (16.1%) vs. 22 (22.4%), p 0.030) in automatic vs. echocardiography-guided group of patients. At multivariate Cox regression analysis, the automatic guided approach (3.636 [1.271–10.399], CI 95%, p 0.016) and baseline highest values of atrium pressure (automatic SonR values, 2.863 [1.537–6.231], CI 95%, p 0.006) predicted rate of CRTd responders. In automatic group, we had significant difference in SonR values comparing the rate of CRTd responders vs. non responders (1.24 ± 0.72 g vs. 0.58 ± 0.46 g (follow-up), p 0.001), the rate of hospitalizations for HF worsening events (0.48 ± 0.29 g vs. 1.18 ± 0.43 g, p 0.001), and the rate of cardiac deaths (1.13 ± 0.72 g vs. 0.65 ± 0.69 g, p 0.047). Conclusions: Automatic optimization increased CRTd responders rate, and reduced hospitalizations for HF worsening. Intriguingly, automatic CRTd and highest baseline values of SonR could be predictive of CRTd responders. Notably, th
