OBJECTIVES: We described clinical-epidemiological features of prosthetic valve endocarditis (PVE) and assessed the determinants of early surgical outcomes in multicentre design.METHODS: Data regarding 2823 patients undergoing surgery for endocarditis at 19 Italian Centers between 1979 and 2015 were collected in a database. Of them, 582 had PVE: in this group, the determinants of early mortality and complications were assessed, also taking into account the different chronological eras encompassed by the study.RESULTS: Overall hospital (30-day) mortality was 19.2% (112 patients). Postoperative complications of any type occurred in 256 patients (44%). Across 3 eras (1980-2000, 2001-08 and 2009-14), early mortality did not significantly change (20.4%, 17.1%, 20.5%, respectively, P = 0.60), whereas complication rate increased (18.5%, 38.2%, 52.8%, P -2 mg/dl, chronic pulmonary disease, low ejection fraction, non-streptococcal aetiology, active endocarditis, preoperative intubation, preoperative shock and triple valve surgery were significantly associated with mortality. In multivariable analysis, age (OR = 1.02; P = 0.03), renal insufficiency (OR = 2.1; P = 0.05), triple valve surgery (OR = 6.9; P = 0.004) and shock (OR = 4.5; P CONCLUSIONS: PVE surgery remains a high-risk one. The strongest predictors of early outcome of PVE surgery are related to patient's haemodynamic status and microbiological factors.

- Abstract
Objective: Transcatheter aortic valve implant (TAVI) is the gold standard for the high-surgical-risk group of patients with aortic valve disease and it is an alternative to surgery in patients at intermediate risk. Lethal complications can occur, and many of these are manageable only with emergent conversion to open heart surgery. We retrospectively evaluate the outcome of all patients undergoing TAVI in our departments and the impact of a complete cardiac rescue team to reduce 30-day mortality., Methods: Data from all patients undergoing TAVI between January 2020 and August 2023 in our center were analyzed. An expert complete rescue was present in catheter laboratory. Primary outcomes were in-hospital and at 30-day mortality and evaluation of all cases needed for emergent conversion to open heart surgery., Results: 825 patients were enrolled. The total mortality was 19/825 (2.3%). Eleven of the total patients (1.3%) required emergent conversion to open heart surgery. Among them, eight were alive (73%), with a theoretical decrease of 0.98% in overall mortality., Conclusions: surgical treatment is rare during TAVI. The presence of an expert complete rescue team as support means an increase in survival. Surgery must be used only to restore circulatory and to treat complication while percutaneous approaches should complete the procedure.

- Abstract
Background: The adoption of minimally invasive techniques to perform mitral valve repair surgery is increasing. This is enhanced by the compelling evidence of satisfactory short-term results and lower major morbidity. We analyzed mid-term follow-up results of our experience, and further compared two techniques: isolated leaflet resection and neochord implantation for posterior leaflet prolapse., Methods: Data for all consecutive endoscopic mitral valve repairs via video-assisted right anterior mini-thoracotomy were analyzed between December 2012 and September 2021. The early and mid-term follow-up results were ascertained. The main outcome was the incidence of mortality and the recurrence of significant mitral regurgitation during follow-up which were summarized by the Kaplan-Meier estimator and compared between treatment arms using the stratified log-rank test. Secondary outcomes were the early-postoperative results including 30-days mortality and the occurrence of major complications., Results: A total of 309 patients were included. Along with ring annuloplasty, 136 (44.4%) patients received posterior leaflet resection (122 isolated) whereas 97 (31.1%) underwent posterior leaflet chords implantation (88 isolated). Forty-nine patients had annuloplasty alone. In-hospital mortality was 1.0%. Mean follow-up was 28.8 ± 22.0 months (maximum 8.3 years). Kaplan-Meier survival rate at 5 years was 97.3 ± 1.0%, mitral regurgitation ([Formula: see text]3+) or valve reoperation free-survival at 5 years was estimated as 94.5 ± 2.3%. Subgroup time-to-event analysis for the indexed outcomes showed no statistical significance between the techniques., Conclusions: Endoscopic mitral valve repair is safe and associated with excellent short- and mid-term outcomes. No differences were found between leaflet resection and gore-tex chords implantation for posterior leaflet prolapse., (© 2023. BioMed Central Ltd., part of Springer Nature.)

- Abstract
The oldest known hominin remains in Europe [~1.5 to ~1.1 million years ago (Ma)] have been recovered from Iberia, where paleoenvironmental reconstructions have indicated warm and wet interglacials and mild glacials, supporting the view that once established, hominin populations persisted continuously. We report analyses of marine and terrestrial proxies from a deep-sea core on the Portugese margin that show the presence of pronounced millennial-scale climate variability during a glacial period ~1.154 to ~1.123 Ma, culminating in a terminal stadial cooling comparable to the most extreme events of the last 400,000 years. Climate envelope-model simulations reveal a drastic decrease in early hominin habitat suitability around the Mediterranean during the terminal stadial. We suggest that these extreme conditions led to the depopulation of Europe, perhaps lasting for several successive glacial-interglacial cycles.

- Abstract
Objectives: The need for concomitant tricuspid surgery in patients who need mitral valve surgery casts doubt on its feasibility via a minimally invasive approach. Our goal was to evaluate the short-term outcomes of patients undergoing concomitant mitral and tricuspid valve surgery either with a standard full sternotomy (full-MTS) or a minimally invasive approach (mini-MTS)., Methods: The outcomes of patients who had combined mitral and tricuspid valve surgery in 11 centres were retrospectively evaluated. The primary outcome was the incidence of 30-day mortality. A propensity score matched cohort was selected to create 2 comparable groups stratified by surgery (valve replacement or repair)., Results: During the study period, 1048 consecutive patients had combined mitral and tricuspid valve surgery (730 full-MTS, 318 mini-MTS). The matching procedure paired 192 full-MTS to 192 mini-MTS procedures. After matching, mini-MTS was associated with longer cardiopulmonary bypass [123 min, standard deviation (SD) 46, vs 102 min, SD 36, P = 0.001] and cross-clamping times (89 min, SD 34, vs 78 min, SD 29, P = 0.003). Although the hospital length of stay was shorter (8 days, interquartile range 7-12 vs 9 days, interquartile range 7-14, P = 0.034) with mini-MTS before matching, this difference disappeared after matching. No differences in other major complications or in 30-day mortality were observed: 48 deaths (4.6%), 36 of which (4.9%) occurred in patients who had a full-MTS and 12 (3.8%), in patients who had a mini-MTS (4.7% in both approaches paired by propensity)., Conclusions: The mini-MTS approach proved to be safe and effective in patients requiring concomitant mitral and tricuspid surgery. We could not demonstrate any difference in short-term outcomes between the 2 surgical approaches, indicating that there is not a preferred surgical approach., (© The Author(s) 2022.

- Abstract
Consistent evidence recognizes minimally invasive valve surgery as the top-tier surgical approach for heart valve pathology. Conversely, the overall adoption of minimally invasive coronary surgery remains low. Notwithstanding, excellent clinical outcomes have been recently reported, further consolidating a technique that addresses major concerns associated with the traditional approach for the most frequently performed cardiac operation, including sternal dehiscence (i.e sternal sparing) and stroke (i.e. no-touch aorta), but that also guarantees a reduced resort to blood transfusions, diminished pain and faster recovery. More to the point, the suitability of minimally invasive strategies for combined coronary and valve procedures remains debateable. Almost no reports of such combined procedures are available in literature and the very few published experiences appear scarce and heterogeneous about the surgical access (i.e. single versus bilateral mini-thoracotomy). However, bilateral mini-thoracotomy has been proposed as a feasible and safe strategy for different cardiac operations like surgical ablation and left ventricular assist device implantation, but also for isolated multivessel minimally invasive coronary surgery. Here, we describe the feasibility of combined minimally invasive mitral valve and coronary surgery performed through bilateral mini-thoracotomy and we report outcomes of our initial series of 3 cases., (© The Author(s) 2022.

- Abstract
Aims: To compare early and late mortality of acute isolated tricuspid valve infective endocarditis (TVIE) treated with valve repair or replacement., Methods: Patients who were surgically treated for TVIE from 1983 to 2018 were retrieved from the Italian Registry for Surgical Treatment of Valve and Prosthesis Infective Endocarditis. All the patients were followed up by means of phone interview or calling patient referral physicians or cardiologists. Kaplan-Meier method was used to assess late survival and survival free from TVIE recurrence with log-rank test for univariate comparison. The primary end points were early mortality (30 days after surgery) and long-term survival free from TVIE recurrence., Results: A total of 4084 patients were included in the registry. Among them, 149 patients were included in the study. Overall, 77 (51.7%) underwent TV repair and 72 (48.3%) TV replacement. Early mortality was 9% (13 patients). Expected early mortality according to EndoSCORE was 12%. The TV repair showed lower mortality and major complication rate (7% and 16%), compared with TV replacement (11% and 25%), but statistical significance was not reached. Median follow-up was 19.1 years (14.3-23.8). Late deaths were 30 and IE recurrences were 5. No difference in cardiac survival free from IE was found between the two groups after 20 years (80 ± 6% Repair Group vs 59 ± 13% Replacement Group, P = 0.3)., Conclusions: Overall results indicate that once surgically addressed, TVIE has a low recurrence rate and excellent survival, apparently regardless of the type of surgery used to treat it., (Copyright © 2022 Italian Federation of Cardiology - I.F.C.

- Abstract
Background: Consensus recommendations regarding the threshold levels of cardiac troponin elevations for the definition of perioperative myocardial infarction and clinically important periprocedural myocardial injury in patients undergoing cardiac surgery range widely (from >10 times to ≥70 times the upper reference limit for the assay). Limited evidence is available to support these recommendations., Methods: We undertook an international prospective cohort study involving patients 18 years of age or older who underwent cardiac surgery. High-sensitivity cardiac troponin I measurements (upper reference limit, 26 ng per liter) were obtained 3 to 12 hours after surgery and on days 1, 2, and 3 after surgery. We performed Cox analyses using a regression spline that explored the relationship between peak troponin measurements and 30-day mortality, adjusting for scores on the European System for Cardiac Operative Risk Evaluation II (which estimates the risk of death after cardiac surgery on the basis of 18 variables, including age and sex)., Results: Of 13,862 patients included in the study, 296 (2.1%) died within 30 days after surgery. Among patients who underwent isolated coronary-artery bypass grafting or aortic-valve replacement or repair, the threshold troponin level, measured within 1 day after surgery, that was associated with an adjusted hazard ratio of more than 1.00 for death within 30 days was 5670 ng per liter (95% confidence interval [CI], 1045 to 8260), a level 218 times the upper reference limit. Among patients who underwent other cardiac surgery, the corresponding threshold troponin level was 12,981 ng per liter (95% CI, 2673 to 16,591), a level 499 times the upper reference limit., Conclusions: The levels of high-sensitivity troponin I after cardiac surgery that were associated with an increased risk of death within 30 days were substantially higher than levels currently recommended to define clinically important periprocedural myocardial injury.

- Abstract
Background: Recent data suggested that transcatheter aortic valve replacement (TAVR) may be indicated also for low-risk patients. However, robust evidence is still lacking, particularly regarding valve performance at follow-up that confers a limitation to its use in young patients. Moreover, a literature gap exists in terms of 'real-world' data analysis. The aim of this study is to compare the cost-effectiveness of sutureless aortic valve replacement (SuAVR) versus transfemoral TAVR., Methods: Prospectively collected data were retrieved from a centralized database of nine cardiac surgery centers between 2010 and 2018. Follow-up was completed in June 2019. A propensity score matching (PSM) analysis was performed., Results: Patients in the TAVR group (n=1002) were older and with more comorbidities than SuAVR patients (n=443). The PSM analysis generated 172 pairs. No differences were recorded between groups in 30-day mortality [SuAVR vs TAVR: n=7 (4%) vs n=5 (2.9%); p=0.7] and need for pacemaker implant [n=10 (5.8%) vs n=20 (11.6%); p=0.1], but costs were lower in the SuAVR group (20486.6±4188€ vs 24181.5±3632€; p<0.01). Mean follow-up was 1304±660 days. SuAVR patients had a significantly higher probability of survival than TAVR patients (no. of fatal events: 22 vs 74; p<0.014). Median follow-up was 2231 days and 2394 days in the SuAVR and TAVR group, respectively., Conclusion: The treatment of aortic valve stenosis with surgical sutureless or transcatheter prostheses is safe and effective. By comparing the two approaches, patients who can undergo surgery after heart team evaluation show longer lasting results and a more favorable cost ratio., (Copyright © 2021.

- Abstract
Objective: To analyze Italian Cardiac Surgery experience during the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) identifying risk factors for overall mortality according to coronavirus disease 2019 (COVID-19) status., Methods: From February 20 to May 31, 2020, 1354 consecutive adult patients underwent cardiac surgery at 22 Italian Centers; 589 (43.5%), patients came from the red zone. Based on COVID-19 status, 1306 (96.5%) were negative to SARS-CoV-2 (COVID-N), and 48 (3.5%) were positive to SARS-CoV-2 (COVID-P); among the COVID-P 11 (22.9%) and 37 (77.1%) become positive, before and after surgery, respectively. Surgical procedures were as follows: 396 (29.2%) isolated coronary artery bypass grafting (CABG), 714 (52.7%) isolated non-CABG procedures, 207 (15.3%) two associate procedures, and three or more procedures in 37 (2.7%). Heart failure was significantly predominant in group COVID-N (10.4% vs. 2.5%, p = .01)., Results: Overall in-hospital mortality was 1.6% (22 cases), being significantly higher in COVID-P group (10 cases, 20.8% vs. 12, 0.9%, p < .001). Multivariable analysis identified COVID-P condition as a predictor of in-hospital mortality together with emergency status. In the COVID-P subgroup, the multivariable analysis identified increasing age and low oxygen saturation at admission as risk factors for in-hospital mortality., Conclusion: As expected, SARS-CoV-2 infection, either before or soon after cardiac surgery significantly increases in-hospital mortality. Moreover, among COVID-19-positive patients, older age and poor oxygenation upon admission seem to be associated with worse outcomes., (© 2021 Wiley Periodicals LLC.)

- Abstract
Background: Patients undergoing transcatheter aortic valve replacement (TAVR) usually have multiple comorbidities, such as severely impaired left ventricular function (LVF) and heavily calcified coronary lesions. When they undergo pre-TAVR high-risk percutaneous coronary interventions (HR-PCIs) for severely calcified left main (LM) lesions, potential life-threatening intra-procedural complications associated with the different techniques available to treat calcified lesions can arise. In this setting, mechanical circulatory support proves its usefulness. However, the choice of device can be troublesome., Case Summary: We report two clinical scenarios of intravascular lithotripsy (IVL) for the treatment of heavily calcified LM coronary lesions, wherein peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO), alone or combined with an intra-aortic balloon pump (IABP), were used as an upfront strategy to support the procedure. The use of these techniques was particularly effective during multi-vessel HR-PCIs and TAVR, and no complications occurred, which suggested their safety., Discussion: These cases provide multiple insights into the strategy of using IVL + VA-ECMO, alone or with IABP, to treat heavily calcified LM coronary lesions in patients with severely compromised LVF undergoing TAVR. IVL safely and effectively overcame shortcomings related to other plaque ablation techniques, and VA-ECMO proved to be effective when facing the combination of high-risk coronary and valve interventions., (© The Author(s) 2021.

- Abstract
Objective: The use of minimally invasive or transcatheter interventions rather than standard full sternotomy operations to treat tricuspid valve (TV) disease is increasing. The debate however is still open regarding venous drainage management during cardiopulmonary bypass (CPB) and wheatear or not superior and inferior vena cava should be occluded during the opening of the right atrium to avoid air entrance in the venous line. The aim of the present study is to report operative outcomes and midterm follow-up results of minimally invasive TV surgery performed without caval occlusion., Methods: A retrospective outcome evaluation from institutional records was performed with prospective data entry. Considered were consecutive patients who underwent right mini-thoracotomy TV surgery isolated or combined with mitral valve surgery during the period from June 2013 to February 2020. A telephone and echocardiographic follow-up was performed., Results: During the study period, 68 consecutive patients underwent minimally invasive TV surgery without occlusion of cava veins. The mean age was 69 ± 14 years and 48 (70%) were female. All operations were performed safely without air-lock during CPB. A perioperative cerebral stroke occurred in one patient. The survival at a 5- and 8-year follow-up was 100% and 79%, respectively. No severe tricuspid regurgitation was evident at echocardiographic follow-up., Conclusion: Our results show that performing tricuspid surgery without caval occlusion is safe. The air was captured by the active vacuum drainage system without causing damage. Midterm follow-up data confirm that a minimally invasive approach does not alter the quality of surgery., (© 2021 Wiley Periodicals LLC.)

- Abstract
Background: The aim of this multicenter prospective study was to evaluate the prognostic weight of preoperative right ventricular assessment on early mortality in cardiac surgery., Methods: This is a multicenter prospective observational study performed by the Italian Group of Research for Outcome in Cardiac Surgery (GIROC) including 11 centers. From October 2017 to March 2019, out of 923 patients undergoing cardiac surgery, 28 patients with some missing data were excluded and 895 patients were enrolled in the study right ventricular dilatation was defined as a basal end-diastolic diameter >42 mm. The right ventricle (RV) function was assessed using the combination of three parameters: fractional area changing (FAC), tricuspid annular plane systolic excursion (TAPSE), and S'-wave using tissue Doppler imaging (TDI-S'); RV dysfunction was defined as the presence of at least two of the following cutoffs: FAC <35%, TAPSE <17 mm, and TDI S' <9.5 mm RESULTS: Among the entire cohort, 624 (70%) showed normal RV, 92 (10%) isolated RV dilatation, 154 (17%) isolated RV dysfunction, and 25 (3%) both RV dilatation and dysfunction. Non-surviving patients showed a significantly higher rate of RV alteration at multivariable analysis, RV status was found to be an independent predictor for higher in-hospital mortality beside Euroscore II., Conclusions: This prospective multicenter observation study shows the importance to assess RV preoperatively and to include both RV function and dimension in a risk score model such as Euroscore II to implement its predictivity, since PH cannot always mirror the status of the right ventricle., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: Mitral valve surgery (MVS) is evolving. Compared to standard sternotomy (S-MVS), minimally invasive method (Mini-MVS) has been increasingly adopted in the last years with encouraging results for both repairs and replacements. We evaluated trends of surgical approaches and operative outcomes in a multicenter study involving 10 cardiac surgical centers in Italy., Methods: Patients who received isolated mitral valve surgery, including only a concomitant tricuspid valve repair, from January 2011 up to December 2017. Minimally invasive approach (right anterior mini-thoracotomy) and standard sternotomy was performed in 2602 and 1947 patients, respectively. Stratifying by surgery, 1493 patients per group were paired using a propensity matching procedure., Results: The minimally invasive approach has been progressively more frequent over the years (from 27.5% in 2011 to 71.7% in 2017). Compared to S-MVS, Mini-MVS patients were younger with less preoperative comorbidities and less frequently operated for valve replacement or in association with tricuspid repair. The 30-day mortality was lower in the Mini-MVS (overall 1.2% vs 2.7%; p < 0.001) as well as the incidence of most postoperative complications. Subjects paired by propensity score had similar 30-day mortality (1.9% vs 1.8%, p = 0.786) but lower blood transfusion and permanent pace-maker insertion. Cardiopulmonary bypass and cross-clamp time, initially longer in the Mini-MVS patients, became shorter in recent years for the minimally invasive approach., Conclusions: In a large multi-institutional recent cohort, minimally invasive mitral valve surgery has drastically increased being the preferred technique and appears to be safe with procedural duration shorter than the beginning., Competing Interests: Declaration of competing interest None declared., (Copyright © 2019 Elsevier B.V.

- Abstract
Objectives: Surgical aortic valve replacement (AVR) can be performed via a full sternotomy or a minimal access approach (mini-AVR). Despite long-term experience with the procedure, mini-AVR is not routinely adopted. Our goal was to compare contemporary outcomes of mini-AVR and conventional AVR in a large multi-institutional national cohort., Methods: A total of 5801 patients from 10 different centres who had a mini-AVR (2851) or AVR (2950) from 2011 to 2017 were evaluated retrospectively. Standard aortic prostheses were used in all cases. The use of the minimally invasive approach has increased over the years. The primary outcome is the incidence of 30-day deaths following mini-AVR and AVR. Secondary outcomes are the occurrence of major complications following both procedures. Propensity-matched comparisons were performed based on the multivariable logistic regression model., Results: In the overall population patients who had AVR had an increased surgical risk based on the EuroSCORE, and the 30-day mortality rate was higher (1.5% and 2.3% in mini-AVR and AVR, respectively; P = 0.048). Propensity scores identified 2257 patients per group with similar baseline profiles. In the matched groups, patients who had mini-AVR, despite longer cardiopulmonary bypass (81 ± 32 vs 76 ± 28 min; P = 0.004) and cross-clamp (64 ± 24 vs 59 ± 21 min; P ≤ 0.001) times, had lower 30-day mortality rates (1.2% vs 2.0%; P = 0.036), reduced low cardiac output (0.8% vs 1.4%; P = 0.046) and reduced postoperative length of stay (9 ± 8 vs 10 ± 7 days; P = 0.004). Blood transfusions (36.4% vs 30.8%; P ≤ 0.001) and atrial fibrillation (26.0% vs 21.5%, P ≤ 0.001) were higher in patients who had the mini-AVR., Conclusions: In a large multi-institutional recent cohort, minimal access approach aortic valve replacement is associated with reduced 30-day mortality rates and shorter postoperative lengths of stay compared to standard sternotomy. A prospective randomized trial is needed to overcome the possible biases of a retrospective study., (© The Author(s) 2019.

- Abstract
Background: Porcine and pericardial valves exhibited similar freedom from structural valve deterioration after aortic valve replacement. Limited data exist regarding their durability at long-term follow-up in the mitral position., Methods: A literature search was performed through online databases. Papers reporting freedom from tissue valve deterioration after mitral valve replacement with a follow-up longer than 5 years were retrieved. Four porcine valves (Carpentier-Edwards [Edwards Lifesciences, Irvine, CA] and Hancock, Hancock II, and Mosaic [Medtronic, Inc, Minneapolis, MN]) and 1 pericardial prosthesis (Carpentier-Edwards) were the objects of the study. The structural valve deterioration (SVD) rate per year was calculated for each type of prosthesis. Kaplan-Meier curves and log-rank test analysis were performed to compare the long-term durability of porcine and pericardial valves., Results: Forty full-text papers including more than 15,000 patients were considered for the meta-analysis. Porcine valves were generally implanted in younger patients in the first period after their introduction. The mean age of the patients receiving a mitral bioprosthesis increased from 50 to 70 years over the decades. In patients operated after 1980 who had similar mean age at the time of implant, freedom from SVD was higher in the group of porcine valves with Mosaic prosthesis, showing the lowest rate of SVD. Long-term survival was higher for Mosaic porcine and Carpentier pericardial valves., Conclusions: In surgical populations that underwent mitral valve replacement after 1980 with new generation tissue valves and similar mean age at the implant time, we found, at long-term follow-up, a higher freedom from SVD in the group of porcine prostheses., (Copyright © 2020 The Society of Thoracic Surgeons.

- Abstract
Background: Aortic valve endocarditis remains a life-threatening condition, especially in cases of periannular complications. Aorto-ventricular discontinuity associated with proximal false aneurysm represents a severe picture caused by extensive tissue disruption and is usually associated with prosthetic valve infection. Complex surgical repair is required in these cases and continues to be associated with high mortality and morbidity rates., Methods: We retrieved information for 32 patients undergoing operation for infective aortic valve/prosthetic valve endocarditis complicated by pseudoaneurysm arising from aorto-ventricular discontinuity. Patients were relatively young, mostly male and most of them had a prior cardiac operation. Aortic root replacement with valve graft conduit was performed in all cases; it was associated with other procedures in seven patients: CABG (n=2), MV surgery (n=3), MV surgery + CABG (n=1) and pulmonary valve replacement (n=1). We reported and analysed patient outcomes at early and mid-term follow-up., Results: Pre-discharge mortality was 22% (n=7). The postoperative course was complicated in 24 (75%) cases. Eighteen patients (56%) sustained low cardiac output resulting in multiple organ failure syndrome and death in five cases. One patient (3%) experienced a major neurologic deficit with a permanent cerebral stroke. Acute kidney injury complicated the course in 12 cases (37%), continuous renal replacement therapy was necessary in four patients (12%). Overall survival and freedom from endocarditis and reoperation at 5-year was 59% and 89%, respectively., Conclusions: Patients with complicated aortic valve endocarditis presented generally in a poor preoperative state. Surgical treatment poses a non-negligible risk of postoperative mortality and morbidity but provides an acceptable survival rate and a satisfactory recovery at mid-term., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2019 Annals of Cardiothoracic Surgery.

- Abstract
Background: To assess early and late mortality in patients with isolated acute tricuspid valve infective endocarditis (TVIE) using data from a multicenter registry., Methods: From 1983 to 2018, isolated acute TVIE was surgically treated in 157 (3.8%) patients [mean age 47 ± 16 years (range 15-86 years), 25% females]. Of these, 142 (90%) had native tricuspid regurgitation, 7 (5%) native tricuspid valve (TV) steno-regurgitation, and 8 (5%) prosthetic TVIE. Intravenous drug use (IVDU) was recorded in 38% of patients, infection involved cardiac implantable electronic device leads in 21%, and vascular catheters for dialysis in 1%; in the remaining cases, the cause was unknown. The primary endpoint was in-hospital outcome, long-term freedom from recurrence and overall survival., Results: Overall, 77 (49%) patients underwent TV repair, 72 (46%) TV replacement, and 8 (5%) prosthetic TV replacement. Early mortality was 11% (n = 17). Expected early mortality according to EndoSCORE was 12%, with age (odds ratio 1.06) and redo (odds ratio 6.64) as risk factors. Late deaths occurred in 31 patients and TVIE recurrences in 4. Survival rates at 10, 20, and 25 years were 66%, 60%, and 44%, respectively. Risk factors were age [hazard ratio (HR) 1.06], mycotic TVIE (HR 4.2), IVDU (HR 4.90), infected prosthesis replacement (HR 4.4), and presence of cardiac implantable electronic device leads (HR 3.0). No significant difference was found in valve repair vs. replacement and in IVDUs vs. non-IVDUs., Conclusions: Patients with isolated acute TVIE undergoing surgical treatment show acceptable early and late outcomes. TVIE recurrence was low, and repair of the affected valve does not seem to confer any advantage either at early or long term up to 25 years., (Copyright © 2019 Elsevier B.V. All rights reserved.)

- Abstract
Objectives: Cardiac surgery induces a systemic inflammatory reaction that has been associated with postoperative mortality and morbidity. Many studies have characterized this reaction through laboratory biomarkers while clinical studies generally are lacking. This study aimed to assess the incidence of postoperative systemic inflammation after cardiac surgery, and the association of postoperative systemic inflammation with preoperative patients' characteristics and postoperative outcomes., Design: Retrospective analysis of prospectively collected data. Analysis of the overall population and of propensity-matched subgroups., Setting: Cardiac surgery intensive care unit., Patients: Adult patients who underwent cardiac surgery with cardiopulmonary bypass (CPB) between June 2016 and June 2017., Interventions: Mixed cardiac surgery operations on CPB., Measurements and Main Results: During the study period, 502 patients underwent cardiac surgery with CPB. One hundred forty-two patients (28.3%) fulfilled SIRS criteria at 24 hours. After performing a multivariate analysis to adjust for the procedure type and preoperative systemic inflammatory reaction syndrome (SIRS) parameters, the occurrence of SIRS was associated inversely with age and extracardiac arteriopathy, and it was associated positively with preoperative white blood cell count. Vasopressors were used more frequently in SIRS patients who further experienced longer mechanical ventilation time and length of stay in the intensive care unit (ICU). The incidence of a composite outcome including death, transient ischemic attack/stroke, renal replacement therapy, bleeding, postoperative intra-aortic balloon pump insertion, and a length of stay in ICU >96 hours was more frequent in SIRS-positive patients. There was no difference between overall and matched subgroups for in-hospital mortality., Conclusion: In this retrospective study, the clinical signs of SIRS were detected in a substantial percentage of patients who underwent cardiac surgery. The postoperative SIRS criteria were associated with a more complicated postoperative course and higher postoperative morbidity., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Background: Minimally invasive cardiac surgery has increasingly been used for patients with valvular pathology. Two techniques of aortic occlusion are utilized with this technique: transthoracic aortic clamp (TTC) and endoaortic balloon occlusion (EAO). Both possibilities present peculiar advantages and limitations whose current evidence is based on few observational studies. We performed an analysis with the primary objective to evaluate outcomes and the incidence of major complications of these two techniques., Methods: The data of 258 patients who underwent minimally invasive mitral valve surgery through right mini-thoracotomy from January 2013 to July 2018 were reviewed. One hundred sixty-five patients were operated on with TTC and in 93 cases EAO was used. Univariate and multivariate analyses were performed to identify predictors of adverse outcome., Results: The mean age of the cohort was 60.4±13.9 years, patients with TTC were significantly older and had higher EuroSCORE II and reoperations were carried out mostly with EAO. Isolated mitral valve surgery was mostly performed (74%) and in 26% of the cases, other procedures were combined. No differences were detected in terms of types of operation, cardiopulmonary bypass (CPB) and cross-clamp times between the two techniques. Similar postoperative troponin I and CK-Mb values were recorded. Twenty-four patients (11%) suffered at least one complication. Of note, a new neurologic deficit occurred in six patients; in four cases a cerebral stroke, with all patients in the EAO group (P=0.06). There was no case of aortic dissection, no patient suffered peripheral ischemia nor femoral vessels complications. Thirty-day mortality was 1.9% (TTC 1.2% vs. EAO 3.2%; P=0.51), 30-day mortality excluding reoperations was 1.2% (TTC 1.2% vs. EAO 1.1%; P=0.61)., Conclusions: Both techniques proved to be safe. Although non-statistically significant, there was a higher rate of cerebral stroke in the EAO group. However, EAO system shows technical advantages in avoiding tissue dissection and remains our choice in redo operations., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

- Abstract
Context: Increased apoptosis of cardiomyocytes and cardiac progenitor cells (CPCs) in response to saturated fatty acids (SFAs) can lead to myocardial damage and dysfunction. Ceramides mediate lipotoxicity-induced apoptosis. Glucagonlike peptide-1 receptor (GLP1R) agonists exert beneficial effects on cardiac cells in experimental models., Objective: To investigate the protective effects of GLP1R activation on SFA-mediated apoptotic death of human CPCs., Design: Human CPCs were isolated from cardiac appendages of nondiabetic donors and then exposed to palmitate with or without pretreatment with the GLP1R agonist exendin-4. Ceramide accumulation was evaluated by immunofluorescence. Expression of key enzymes in de novo ceramide biosynthesis was studied by quantitative reverse-transcription polymerase chain reaction and immunoblotting. Apoptosis was evaluated by measuring release of oligonucleosomes, caspase-3 cleavage, caspase activity, and terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling., Results: Exposure of the CPCs to palmitate resulted in 2.3- and 1.9-fold higher expression of ceramide synthase 5 (CERS5) and ceramide desaturase-1, respectively (P < 0.05). This was associated with intracellular accumulation of ceramide and activation of c-Jun NH2-terminal protein kinase (JNK) signaling and apoptosis (P < 0.05). Both coincubation with fumonisin B1, a specific ceramide synthase inhibitor, and CERS5 knockdown prevented ceramide accumulation, JNK activation, and apoptosis in response to palmitate (P < 0.05). Exendin-4 also prevented the activation of the ceramide biosynthesis and JNK in response to palmitate, inhibiting apoptosis (P < 0.05)., Conclusions: Excess palmitate results in activation of ceramide biosynthesis, JNK signaling, and apoptosis in human CPCs. GLP1R activation counteracts this lipotoxic damage via inhibition of ceramide generation, and this may represent a cardioprotective mechanism., (Copyright © 2017 Endocrine Society)

- Abstract
Background: The aim of this large retrospective study was to provide a logistic risk model along an additive score to predict early mortality after surgical treatment of patients with heart valve or prosthesis infective endocarditis (IE)., Methods: From 2000 to 2015, 2715 patients with native valve endocarditis (NVE) or prosthesis valve endocarditis (PVE) were operated on in 26 Italian Cardiac Surgery Centers. The relationship between early mortality and covariates was evaluated with logistic mixed effect models. Fixed effects are parameters associated with the entire population or with certain repeatable levels of experimental factors, while random effects are associated with individual experimental units (centers)., Results: Early mortality was 11.0% (298/2715); At mixed effect logistic regression the following variables were found associated with early mortality: age class, female gender, LVEF, preoperative shock, COPD, creatinine value above 2mg/dl, presence of abscess, number of treated valve/prosthesis (with respect to one treated valve/prosthesis) and the isolation of Staphylococcus aureus, Fungus spp., Pseudomonas Aeruginosa and other micro-organisms, while Streptococcus spp., Enterococcus spp. and other Staphylococci did not affect early mortality, as well as no micro-organisms isolation. LVEF was found linearly associated with outcomes while non-linear association between mortality and age was tested and the best model was found with a categorization into four classes (AUC=0.851)., Conclusions: The following study provides a logistic risk model to predict early mortality in patients with heart valve or prosthesis infective endocarditis undergoing surgical treatment, called "The EndoSCORE"., (Copyright © 2017.

- Abstract
Objectives: We described clinical-epidemiological features of prosthetic valve endocarditis (PVE) and assessed the determinants of early surgical outcomes in multicentre design., Methods: Data regarding 2823 patients undergoing surgery for endocarditis at 19 Italian Centers between 1979 and 2015 were collected in a database. Of them, 582 had PVE: in this group, the determinants of early mortality and complications were assessed, also taking into account the different chronological eras encompassed by the study., Results: Overall hospital (30-day) mortality was 19.2% (112 patients). Postoperative complications of any type occurred in 256 patients (44%). Across 3 eras (1980-2000, 2001-08 and 2009-14), early mortality did not significantly change (20.4%, 17.1%, 20.5%, respectively, P = 0.60), whereas complication rate increased (18.5%, 38.2%, 52.8%, P < 0.001), consistent with increasing mean patient age (56 ± 14, 64 ± 15, 65 ± 14 years, respectively, P < 0.001) and median logistic EuroSCORE (14%, 21%, 23%, P = 0.025). Older age, female sex, preoperative serum creatinine >-2 mg/dl, chronic pulmonary disease, low ejection fraction, non-streptococcal aetiology, active endocarditis, preoperative intubation, preoperative shock and triple valve surgery were significantly associated with mortality. In multivariable analysis, age (OR = 1.02; P = 0.03), renal insufficiency (OR = 2.1; P = 0.05), triple valve surgery (OR = 6.9; P = 0.004) and shock (OR = 4.5; P < 0.001) were independently associated with mortality, while streptococcal aetiology, healed endocarditis and ejection fraction with survival. Adjusting for study era, preoperative shock (OR = 3; P < 0.001), Enterococcus (OR = 2.3; P = 0.01) and female sex (OR = 1.5; P = 0.03) independently predicted complications, whereas ejection fraction was protective., Conclusions: PVE surgery remains a high-risk one. The strongest predictors of early outcome of PVE surgery are related to patient's haemodynamic status and microbiological factors., (© The Author 2017.

- Abstract
Cardiopulmonary bypass (CPB) surgery, despite heparin administration, elicits activation of coagulation system resulting in coagulopathy. Anti-inflammatory effects of steroid treatment have been demonstrated, but its effects on coagulation system are unknown. The primary objective of this study is to assess the effects of methylprednisolone on coagulation function by evaluating thrombin generation, fibrinolysis, and platelet activation in high-risk patients undergoing cardiac surgery with CPB. The Steroids In caRdiac Surgery study is a double-blind, randomized, controlled trial performed on 7507 patients worldwide who were randomized to receive either intravenous methylprednisolone, 250 mg at anesthetic induction and 250 mg at initiation of CPB (n = 3755), or placebo (n = 3752). A substudy was conducted in 2 sites to collect blood samples perioperatively to measure prothrombin fragment 1.2 (PF1+2, thrombin generation), plasmin-antiplasmin complex (PAP, fibrinolysis), platelet factor 4 (PF4 platelet activation), and fibrinogen. Eighty-one patients were enrolled in the substudy (37 placebo vs 44 in treatment group). No difference in clinical outcome was detected, including postoperative bleeding and need for blood products transfusion. All patients showed changes of all plasma biomarkers with greater values than baseline in both groups. This reaction was attenuated significantly in the treatment group for PF1.2 (P = 0.040) and PAP (P = 0.042) values at the first intraoperative measurement. No difference between groups was detected for PF4. Methylprednisolone treatment attenuates activation of coagulation system in high-risk patients undergoing CPB surgery. Reduction of thrombin generation and fibrinolysis activation may lead to reduced blood loss after surgery., (Copyright © 2017 Elsevier Inc. All rights reserved.)

- Abstract
Thoracic endovascular aortic repair (TEVAR) is effectively executed in patients with arch or descending aortic diseases. Peripheral access sites are preferably used as standard gates for TEVAR. Feasibility of a peripheral approach might need an intraoperative evaluation and alternative routes should have been carefully assessed. In this article, we report 2 successful cases of direct transaortic TEVAR, where stent grafts were directly introduced into the native ascending aorta without external conduits. A satisfactory result and the absence of aortic-related complications were observed at 2 and 5 years' follow-up, respectively., (Copyright © 2016 The Society of Thoracic Surgeons.
