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.

Abstract
Scarce data exist on mitral valve (MV) infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). This multicenter study included a total of 579 patients with a diagnosis of definite IE after TAVI from the IE after TAVI International Registry and aimed to evaluate the incidence, characteristics, management, and outcomes of MV-IE after TAVI. A total of 86 patients (14.9%) had MV-IE. These patients were compared with 284 patients (49.1%) with involvement of the transcatheter heart valve (THV) only. Two factors were found to be associated with MV-IE: the use of self-expanding valves (adjusted odds ratio 2.49, 95% confidence interval [CI] 1.23 to 5.07, p = 0.012), and the presence of an aortic regurgitation ≥2 at discharge (adjusted odds ratio 3.33; 95% CI 1.43 to 7.73, p <0.01). There were no differences in IE timing and causative microorganisms between groups, but surgical management was significantly lower in patients with MV-IE (6.0%, vs 21.6% in patients with THV-IE, p = 0.001). All-cause mortality rates at 2-year follow-up were high and similar between patients with MV-IE (51.4%, 95% CI 39.8 to 64.1) and patients with THV-IE (51.5%, 95% CI 45.4 to 58.0) (log-rank p = 0.295). The factors independently associated with increased mortality risk in patients with MV-IE were the occurrence of heart failure (adjusted p <0.001) and septic shock (adjusted p <0.01) during the index hospitalization. One of 6 IE episodes after TAVI is localized on the MV. The implantation of a self-expanding THV and the presence of an aortic regurgitation ≥2 at discharge were associated with MV-IE. Patients with MV-IE were rarely operated on and had a poor prognosis at 2-year follow-up.

Abstract
Abstract
Introduction
Cardiac Allograft Vasculopathy (CAV) is a leading cause of long–term graft dysfunction and failure after Heart Transplant (HTx). Early diagnosis is crucial to tailor therapeutic strategies. Despite advancements in cardiac imaging, the standard for CAV diagnosis remains coronary angiography. Donor–derived cell free DNA (dd–cfDNA) is a novel marker of graft injury in solid organ transplants. Elevations in dd–cfDNA levels may reflect CAV development during subclinical inflammation, thus it could represent a non–invasive method of surveillance for CAV rejection in apparently stable post–transplant patients. Given these premises, we decided to evaluate the potential of dd–cfDNA as alternative diagnostic biomarker for CAV.
Materials and Methods
31 blood samples from patients who underwent heart transplant at our institution in the last 10 years, were analyzed by Next Generation Sequencing (NGS) according to CareDx Alloseq protocol. The cfDNA was extracted starting from 2mL of plasma (Qiagen). Sequencing was performed on the Illumina Miseq platform. Troponin T (hs–TnT) and NT–proBNP (Brain Natriuretic Peptide) were measured by automated immunoassay analysers. All statistics were performed by STATA software and significance was set at p < 0.05.
Results
Heart transplant recipients were divided into 2 groups: 16 patients with known CAV status and 15 patients who had not (no–CAV). No significant differences between the two populations were observed, aside from time from HTx (177.28± 84.99 months in CAV vs 93.20 ± 84.39 months in no–CAV; p = 0.033). A significant difference in dd–cfDNA fraction was found between CAV and no–CAV patients (p = 0.03); with mean values of 0,41% e 0,13%, respectively. Neither NT-proBNP (p = 0.08) nor hs–TnT (p = 0.31) concentrations were significantly different between the two groups, but a positive correlation was found between the two biomarkers (r 0.6966; p = 0.0013). A trend of linear relationship emerged between cfDNA and NT-proBNP levels (r 0.4155; p = 0.08).
Conclusions
With this study, we demonstrated the feasibility of evaluating dd–cfDNA in long–term heart transplanted patients and its possible association with CAV development. Further investigations are warranted to explore a possible association between dd–cfDNA levels other circulating biomarkers and CAV progression. The definition of “homogeneous” subgroups of patients according to a “risk score” will allow to better manage their follow up and improve their prognosis.

Abstract
Abstract
Objective
To analyse the effects of chronic oral anticoagulation on long–term outcomes after repair of type A acute aortic dissection and its influence on false lumen fate.
Methods
We studied 188 patients (median age 62 years; 74% males) who had repair of type A aortic dissection; patients receiving postoperative chronic oral anticoagulation (n = 59) were compared to those on antiplatelet therapy alone (n = 129).
Results
Median age was similar: 60 (18–79 years) vs 64 years (22–86) (p = 0.11); patients on anticoagulants were more frequently males (88% vs 67%, p = 0.003). After a median follow–up of 8.4 years (2 months to 30 years) 58 patients died, 18 for aortic–related causes, and 37 underwent aortic reintervention. After multivariable adjustment, anticoagulation showed no significant effect on long–term survival (HR 0.85, 95% CI 0.41–1.76; p = 0.66) neither on risk of reintervention (HR 0.55, 95% CI 0.27–1.15; p = 0.11). Analysis of 127 postoperative computed tomography scans showed a patent false lumen in 53% of anticoagulated vs 38% of not anticoagulated patients (p = 0.09); partially thrombosed in 8% vs 28% (p = 0.01) and thrombosed in 39% vs 34% (p = 0.63). In patients with a control computed tomography there were 6 late aortic–related deaths, 1 among patients anticoagulated and 5 in those who were not.
Conclusions
Chronic anticoagulation after repair of type A acute aortic dissection favours persistent late false lumen patency which is not a risk factor for late mortality or reoperation. Chronic anticoagulation can be administered safely to patients with repaired type A acute aortic dissection regardless of its specific indication.

Abstract
Abstract
Background
The outcome of acute type–A aortic dissection (A–AAD) repair is strictly related both to surgical factors and patient conditions. Improvement in surgical experience and in diagnosis and treatment protocols could significantly increase survival for patients affected by A–AAD. The aim of this study was to assess the impact on patients outcomes of a standardized integrated surgical approach and of a regional aortic hub and spokes network.
Materials and Methods
From 2004 to 2021, a total of 258 patients underwent repair of A–AAD. In 2010 in our Institution was created the Aortic Team, with cardiac surgeons dedicated on the treatment of aortic pathologies, while in 2017 was created a regional aortic network between hub and spokes in order to standardize the diagnosis and treatment algorithm. Thus, patients were distributed among three periods: 2004–2010 (Era 1, n = 90), 2011–2016 (Era 2, n = 87), and 2017–2021 (Era 3, n = 81).
Results
Baseline demographic characteristics of the groups were similar. Compared to Era1 and Era2, clinical status at time of operation was better in Era3, because of less rates of malperfusion (16% vs 11% vs 4%, p = 0.01) and hemodynamic compromise (34% vs 38% vs 22%, p = 0.07). Patients of Era 3 were less likely to Axillary artery cannulation was almost routinely used in Eras 2 (86%) and 3 (91%) while femoral artery was mainly cannulated in Era 1 (91%) (p < 0.01). Retrograde cerebral perfusion was predominantly used in Era 1 (60%) while antegrade cerebral perfusion was preferred in Eras 2 (94%,) and 3 (100%); (p < 0.01). There was a significant increase of arch replacement procedures from Era 1 (11%) to Eras 2 (33%) and 3 (48%) (p < 0.01). Frozen elephant trunk was mainly performed in Era 3. Operative mortality was 13% in Era 1, 11% in Era 2, and 4% in Era 3 (p = 0.07, p = 0.03 between Era 1 and Era3). Actuarial survival at 3 years is 74%, in Era 1, 78% in Era 2, and 89% in Era 3 (p = 0.05). Patients of Era 3 received less re–exploration for bleeding (p = 0.02) and less high inotropic support (p = 0.04).
Conclusions
With increasing experience and a more aggressive approach, including total arch replacement, repair of A–AAD can be more tailored to patients conditions, being performed with low operative mortality in many patients. Moreover, patient care and treatment by a multidisciplinary regional organization allows faster diagnosis and effective clinical stabilization allowing to further improve early and late outcomes.

Abstract
Abstract
Background and Aims
Metabolic Syndrome (MS) is a multifactorial condition that increases the risk of cardio–vascular events, it’s frequent in Heart transplant (HTx) candidates and worsens with immunosuppressive therapy.
Aim of the study was to analyse the impact of MS on long–term outcome of HTx patients in our centre.
Methods
MS was defined through the presence of at least 3 of the following factors: Triglyceride ≥150mg/dl or drug treatment for hypertriglyceridemia HDL <40mg/dl for men and <50mg/dl for women Blood glucose ≥100mg/dl or diabetes mellitus Arterial pressure ≥130/80 or hypertensive drug treatment BMI>30. In 349 HTx patients since 2007, mortality and morbidity predictors were evaluated.
Results
MS was present in 35% of patients pre–HTx and 47% within the first year of follow–up. Five–year survival in patients with pre–HTx MS was worst (65% vs 78%, p < 0.01), as well as in those with MS in the first year of follow–up (78% vs 89%, p < 0.01). At the univariate analysis, risk factors for mortality were recipient age (HR 1.07, 1.04–1.09, p < 0.01), pre–HTx MS (HR 1.86, 1.29–2.69, p < 0.01), pre–HTx hypertension (HR 2.46, 1.70–3.55, p < 0.01), pre–HTx hypertriglyceridemia (HR 1.50, 1.04–2.18, p = 0.03), chronic renal failure (HR 2.95, 2.03–4.27, p < 0.01), MS and diabetes at 1–year follow–up (HR 2.00, 1.25–3.19, p < 0.01; HR 2.02, 1.27–3.23, p < 0.01, respectively). The last two resulted also risk factors for CAV (HR 1.86, 1.16–2.99, p = 0.01; HR 1.67, 1.03–2.69, p = 0.04, respectively). MS at 1–year follow–up determined a significant higher risk to develop CAV at 5– and 10–year follow–up, compared to patients without MS (25% vs 14% and 44% vs 25%, p < 0.01).
Conclusions
MS is an important risk factor for both mortality and morbidity post–HTx, suggesting the need for a strict monitoring of metabolic disorders with a careful nutritional follow–up in HTx patients.

Abstract
BACKGROUND Aim of this study is to analyse the performances of Clinical Risk Score (CRS) and European System for Cardiac Operative Risk Evaluation (EuroSCORE)-II in isolated tricuspid surgery. METHODS Three hundred and eighty-three patients (54 ± 16 year; 54% female) were enrolled. Receiver operating characteristic analysis was performed to evaluate the relationship between the true positive fraction of test results and the false-positive fraction for a procedure. RESULTS Considering the 30-day mortality the area under the curve was 0.6 (95% confidence interval [CI] 0.50-0.72) for EuroSCORE II and 0.7 (95% CI 0.56-0.84) for CRS-score. The ratio of expected/observed mortality showed underestimation when considering EuroSCORE-II (min. 0.46-max. 0.6). At multivariate analysis, the CRS score (p = .005) was predictor of late cardiac death. CONCLUSION We suggest using both scores to obtain a range of expected mortality. CRS to speculate on late survival.

Abstract
We report a patient who presented with paraplegia after ascending aorta and arch replacement using the frozen elephant trunk technique. Immediate postoperatively cerebrospinal fluid drainage allowed successful reversal of spinal cord injury. Early awakening of patients following a frozen elephant trunk technique is mandatory because it allows recognition and treatment of this complication by prompt cerebrospinal liquor drainage.

Abstract
BACKGROUND The optimal treatment of patients developing infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is uncertain. OBJECTIVES The goal of this study was to investigate the clinical characteristics and outcomes of patients with TAVI-IE treated with cardiac surgery and antibiotics (IE-CS) compared with patients treated with antibiotics alone (IE-AB). METHODS Crude and inverse probability of treatment weighting analyses were applied for the treatment effect of cardiac surgery vs medical therapy on 1-year all-cause mortality in patients with definite TAVI-IE. The study used data from the Infectious Endocarditis after TAVI International Registry. RESULTS Among 584 patients, 111 patients (19%) were treated with IE-CS and 473 patients (81%) with IE-AB. Compared with IE-AB, IE-CS was not associated with a lower in-hospital mortality (HRunadj: 0.85; 95% CI: 0.58-1.25) and 1-year all-cause mortality (HRunadj: 0.88; 95% CI: 0.64-1.22) in the crude cohort. After adjusting for selection and immortal time bias, IE-CS compared with IE-AB was also not associated with lower mortality rates for in-hospital mortality (HRadj: 0.92; 95% CI: 0.80-1.05) and 1-year all-cause mortality (HRadj: 0.95; 95% CI: 0.84-1.07). Results remained similar when patients with and without TAVI prosthesis involvement were analyzed separately. Predictors for in-hospital and 1-year all-cause mortality included logistic EuroSCORE I, Staphylococcus aureus, acute renal failure, persistent bacteremia, and septic shock. CONCLUSIONS In this registry, the majority of patients with TAVI-IE were treated with antibiotics alone. Cardiac surgery was not associated with an improved all-cause in-hospital or 1-year mortality. The high mortality of patients with TAVI-IE was strongly linked to patients' characteristics, pathogen, and IE-related complications.

Abstract
BACKGROUND Few longitudinal data exist comparing quality of life (QoL) after full sternotomy aortic valve replacement (fsAVR) vs mini-sternotomy AVR (msAVR) METHODS: 1844 consecutive AVR prospectively enrolled in a European multicentre Registry were dichotomized according to surgical access. A non-parsimonious propensity-score matching selected 187 pairs of fsAVR or msAVR with comparable baseline characteristics. Hospital outcome was compared in the two groups. QoL was assessed with Short Form-36, further detailed in its Physical Component Score (PCS) and Mental Component Score (MCS). QoL was investigated at hospital admission, discharge, 1 month, 6 months and 1 year thereafter. RESULTS There were 1654 fsAVR and 190 msAVR in the entire population. fsAVR showed a worse preoperative risk-profile, a longer ICU length of stay (59.7 hours vs 38.8, p=0.002), and a higher life-threatening/disabling bleeding (4.1% vs. 0%; p=0.011); msAVR reported a higher early reintervention for failed index intervention (2.1% vs. 0.5%, p=0.001). QoL showed better PCS and MCS at 1 month after fsAVR, but no temporal-trend differences (PCS group-time p=0.202; MCS group-time p=0.141). Propensity-matched pairs showed comparable baseline characteristics and hospital outcome (p=NS for all endpoints), and comparable improvements of PCS and MCS over time, but no between-group differences over time (PCS group-time p=0.834; MCS group-time p=0.737). CONCLUSIONS Patients with similar baseline profiles report comparable hospital outcome and comparable improvement of physical and mental health, up to 1 year after surgery, with both fsAVR and msAVR. As for QoL, mini-sternotomy does not seem to offer any advantage compared to the traditional approach.

Hemiarch Versus Arch Replacement in Acute Type A Aortic Dissection: Is the Occam's Razor Principle Applicable? J Clin Med 2021; 11:jcm11010114. [PMID: 35011856 PMCID: PMC8745476 DOI: 10.3390/jcm11010114] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Revised: 11/25/2021] [Accepted: 12/23/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND AND AIM OF THE STUDY In patients with acute Type A aortic dissection (A-AAD) whether repair should be limited to ascending aorta/hemiarch replacement or extended to include the aortic arch is still debated. We have analyzed our experience to compare outcomes of patients with A-AAD treated with these 2 different surgical strategies. METHODS From 2006 to 2020, a total of 213 patients have undergone repair of A-AAD at our Center; in 163 of them ascending aorta/hemiarch replacement (Group 1) and in 75 ascending aorta and arch replacement (Group 2) were performed. The primary endpoint was early survival and secondary endpoints late survival, freedom from late complications and reoperations. Patients were compared according to era of operation: 2006 to 2013 (Era 1) and 2014 to 2020 (Era 2). RESULTS Overall hospital mortality was 12% and 5% in Group 1 and 2; mortality remained stable in Era 1 and 2 for Group 1 (15%), while it decreased from 8% to 1% in Group 2 patients (p = 0.24). Actuarial survival at 5 and 10 years is 72 ± 4% and 49 ± 5% in Group 1 and 77 ± 6% and 66 ± 9% in Group 2 (p = 0.073). Actuarial freedom from reoperation in the entire series is 94 ± 2% and 92 ± 3% at 5 and 10 years. Freedom from reoperation at 5 and 10 years is 92 ± 2% and 89 ± 3% in Group 1 and 98 ± 1% at all intervals in Group 2 (p = 0.068). CONCLUSIONS An aggressive approach to A-AAD provides superior long-term results without increasing mortality. Furthermore, arch replacement during A-AAD repair represents a more stable solution with lower incidence of late aortic-related complications. Immediate aortic arch replacement should be considered in the treatment of A-AAD especially in experienced centers.

Abstract
BACKGROUND Infective endocarditis (IE) following transcatheter aortic valve replacement (TAVR) has been associated with a dismal prognosis. However, scarce data exist on IE perivalvular extension (PEE) in such patients. METHODS This multicenter study included a total of 579 patients who had the diagnosis of definite IE at a median of 171 (53-421) days following TAVR. PEE was defined as the presence of an intracardiac abscess, pseudoaneurysm or fistula confirmed by transthoracic/transophageal echocardiography, computed tomography or peri-operative findings. RESULTS A total of 105 patients (18.1%) were diagnosed with PEE (perivalvular abscess, pseudoaneurysm, fistula, or a combination in 87, 7, 7, and 4 patients, respectively). A history of chronic kidney disease (ORadj: 2.08; 95% CI: [1.27-3.41], p=0.003) and IE secondary to coagulase-negative staphylococci (ORadj: 2.71; 95% CI: [1.57-4.69], p<0.001) was associated with an increased risk of PEE. Surgery was performed at index IE episode in 34 patients (32.4%) with PEE (vs. 15.2% in patients without PEE, p<0.001). In-hospital and 2-year mortality rates among PEE-IE patients were 36.5% and 69.4%, respectively. Factors independently associated with an increased mortality risk were the occurrence of other complications (stroke post-TAVR, acute renal failure, septic shock) and the lack of surgery at index IE hospitalization (padj<0.05 for all). CONCLUSION PEE occurred in about one fifth of IE post-TAVR patients, with the presence of coagulase-negative staphylococci and chronic kidney disease determining an increased risk. Patients with PEE-IE exhibited very high early and late mortality rates, and surgery during IE hospitalization seemed to be associated with better outcomes.

Abstract
OBJECTIVES Papillary muscle rupture (PMR) is a rare but potentially fatal complication of acute myocardial infarction. The aim of this study was to analyse the patient characteristics and early outcomes of the surgical management of post-infarction PMR from an international multicentre registry. METHODS Patients underwent surgery for post-infarction PMR between 2001 through 2019 were retrieved from database of the CAUTION study. The primary end point was in-hospital mortality. RESULTS A total of 214 patients were included with a mean age of 66.9 (standard deviation: 10.5) years. The posteromedial papillary muscle was the most frequent rupture location (71.9%); the rupture was complete in 67.3% of patients. Mitral valve replacement was performed in 82.7% of cases. One hundred twenty-two patients (57%) had concomitant coronary artery bypass grafting. In-hospital mortality was 24.8%. Temporal trends revealed no apparent improvement in in-hospital mortality during the study period. Multivariable analysis showed that preoperative chronic kidney disfunction [odds ratio (OR): 2.62, 95% confidence interval (CI): 1.07-6.45, P = 0.036], cardiac arrest (OR: 3.99, 95% CI: 1.02-15.61, P = 0.046) and cardiopulmonary bypass duration (OR: 1.01, 95% CI: 1.00-1.02, P = 0.04) were independently associated with an increased risk of in-hospital death, whereas concomitant coronary artery bypass grafting was identified as an independent predictor of early survival (OR: 0.38, 95% CI: 0.16-0.92, P = 0.031). CONCLUSIONS Surgical treatment for post-infarction PMR carries a high in-hospital mortality rate, which did not improve during the study period. Because concomitant coronary artery bypass grafting confers a survival benefit, this additional procedure should be performed, whenever possible, in an attempt to improve the outcome.

Abstract
Background and objective: We reviewed a single-institution experience to verify the impact of surgery during different time intervals on early and late results in the treatment of patients with type A acute aortic dissection (A-AAD). Materials and Methods: From 2004 to 2021, a total of 258 patients underwent repair of A-AAD; patients were equally distributed among three periods: 2004-2010 (Era 1, n = 90), 2011-2016 (Era 2, n = 87), and 2017-2021 (Era 3, n = 81). The primary end-point was to assess whether through the years changes in indications, surgical strategies and techniques and increasing experience have influenced early and late outcomes of A-AAD repair. Results: Axillary artery cannulation was almost routinely used in Eras 2 (86%) and 3 (91%) while one femoral artery was mainly cannulated in Era 1 (91%) (p < 0.01). Retrograde cerebral perfusion was predominantly used in Era 1 (60%) while antegrade cerebral perfusion was preferred in Eras 2 (94%,) and 3 (100%); (p < 0.01). There was a significant increase of arch replacement procedures from Era 1 (11%) to Eras 2 (33%) and 3 (48%) (p < 0.01). A frozen elephant trunk was mainly performed in Era 3. Hospital mortality was 13% in Era 1, 11% in Era 2, and 4% in Era 3 (p = 0.07). Actuarial survival at 3 years is 74%, in Era 1, 78% in Era 2, and 89% in Era 3 (p = 0.05). Conclusions: With increasing experience and a more aggressive approach, including total arch replacement, repair of A-AAD can be performed with low operative mortality in many patients. Patient care and treatment by a specific team organization allows a faster diagnosis and referral for surgery allowing to further improve early and late outcomes.

Abstract
BACKGROUND Staphylococcus aureus (S aureus) has been extensively studied as causative microorganism of surgical prosthetic-valve infective endocarditis (IE). However, scarce evidence exists on S aureus IE after transcatheter aortic valve replacement (TAVR). METHODS Data was obtained from the Infectious Endocarditis after TAVR International Registry including patients with definite IE following TAVR from 59 centers in 11 countries. Patients were divided into two groups according to microbiological etiology (non-S aureus-IE, non-SA-IE vs. S aureus-IE, SA-IE). RESULTS SA-IE was identified in 141 out of 573 (24.6%) patients, methicillin-sensitive S aureus in most cases (115/141, 81.6%). SEV were more common than BEV in patients with early SA-IE. Major bleeding and sepsis complicating TAVR, neurological symptoms or systemic embolism at admission and IE with cardiac device involvement other than the TAVR prosthesis were associated with SA-IE (p<0.05 for all). Among IE post-TAVR patients, the likelihood of SA-IE increased from 19% in the absence of those risk factors to 84.6% if ≥3 risk factors were present. In-hospital (47.8% vs. 26.9%, p<0.001) and 2-year mortality (71.5% vs. 49.6%, p<0.001) rates were higher among SA-IE (vs. non-SA-IE) patients. Surgery at the time of index SA-IE was associated with a lower mortality rate at follow-up (HRadj: 0.46, 95% CI: 0.22-0.96, p=0.038). CONCLUSIONS SA-IE represented ∼ 25% of IE cases after TAVR and was associated with a very high in-hospital and late mortality. The presence of some features determined a higher likelihood of SA-IE and could help to orientate early antibiotic regimen selection. Surgery at index SA-IE was associated with improved outcomes, and its role should be evaluated in future studies.

Abstract
Simultaneous replacement of the ascending aorta and aortic valve has always been a challenging procedure. Introduction of composite conduits, through various ingenious procedures and their modifications, has changed the outlook of patients with aortic valve disease and ascending aorta pathology. In the past 70 years, progress of surgical techniques and prosthetic materials has allowed such patients to undergo radical procedures providing excellent early and long-term results in both young and elderly patients. This article aims to review the most important technical advances in the treatment of aortic valve disease and ascending aorta aneurysms recognizing the important contributions in this field.

Abstract
IMPORTANCE Ventricular septal rupture (VSR) is a rare but life-threatening mechanical complication of acute myocardial infarction associated with high mortality despite prompt treatment. Surgery represents the standard of care; however, only small single-center series or national registries are usually available in literature, whereas international multicenter investigations have been poorly carried out, therefore limiting the evidence on this topic. OBJECTIVES To assess the clinical characteristics and early outcomes for patients who received surgery for postinfarction VSR and to identify factors independently associated with mortality. DESIGN, SETTING, AND PARTICIPANTS The Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort (CAUTION) Study is a retrospective multicenter international cohort study that includes patients who were treated surgically for mechanical complications of acute myocardial infarction. The study was conducted from January 2001 to December 2019 at 26 different centers worldwide among 475 consecutive patients who underwent surgery for postinfarction VSR. EXPOSURES Surgical treatment of postinfarction VSR, independent of the technique, alone or combined with other procedures (eg, coronary artery bypass grafting). MAIN OUTCOMES AND MEASURES The primary outcome was early mortality; secondary outcomes were postoperative complications. RESULTS Of the 475 patients included in the study, 290 (61.1%) were men, with a mean (SD) age of 68.5 (10.1) years. Cardiogenic shock was present in 213 patients (44.8%). Emergent or salvage surgery was performed in 212 cases (44.6%). The early mortality rate was 40.4% (192 patients), and it did not improve during the nearly 20 years considered for the study (median [IQR] yearly mortality, 41.7% [32.6%-50.0%]). Low cardiac output syndrome and multiorgan failure were the most common causes of death (low cardiac output syndrome, 70 [36.5%]; multiorgan failure, 53 [27.6%]). Recurrent VSR occurred in 59 participants (12.4%) but was not associated with mortality. Cardiogenic shock (survived: 95 [33.6%]; died, 118 [61.5%]; P < .001) and early surgery (time to surgery ≥7 days, survived: 105 [57.4%]; died, 47 [35.1%]; P < .001) were associated with lower survival. At multivariate analysis, older age (odds ratio [OR], 1.05; 95% CI, 1.02-1.08; P = .001), preoperative cardiac arrest (OR, 2.71; 95% CI, 1.18-6.27; P = .02) and percutaneous revascularization (OR, 1.63; 95% CI, 1.003-2.65; P = .048), and postoperative need for intra-aortic balloon pump (OR, 2.98; 95% CI, 1.46-6.09; P = .003) and extracorporeal membrane oxygenation (OR, 3.19; 95% CI, 1.30-7.38; P = .01) were independently associated with mortality. CONCLUSIONS AND RELEVANCE In this study, surgical repair of postinfarction VSR was associated with a high risk of early mortality; this risk has remained unchanged during the last 2 decades. Delayed surgery seemed associated with better survival. Age, preoperative cardiac arrest and percutaneous revascularization, and postoperative need for intra-aortic balloon pump and extracorporeal membrane oxygenation were independently associated with early mortality. Further prospective studies addressing preoperative and perioperative patient management are warranted to hopefully improve the currently suboptimal outcome.

Abstract
BACKGROUND AND AIM Blood cysts of cardiac valves are generally seen in newborns and infants and very rarely in adults. Although in most cases they are incidental findings they may be associated to severe cardiac or systemic complications. This study analyzes incidence, presentation, and treatment of valvular blood cysts in adults. METHODS A review of the pertinent literature through a search mainly on PubMed and Medline was performed. RESULTS In patients ≥18 years of age, our search disclosed 54 patients with mitral blood cysts (mean age, 48 ± 18 years), 9 with a tricuspid valve cyst (mean age, 67 ± 15 years), 3 with a blood cyst on the pulmonary valve (age 31, 43, and 44 years), and 1 aortic valve cyst in a 22-year-old man. Most patients were asymptomatic while stroke, syncope, or myocardial infarction occurred in six patients with a mitral valve cyst. Blood cysts were removed surgically in 70% of patients with a mitral cyst, in 55% with a tricuspid cyst, and in all those with a pulmonary or aortic cyst. At histology, the cyst wall was composed mainly by fibrous tissue and with the inner surface lined with typical endothelium. CONCLUSIONS Blood cysts of cardiac valves are rare in adults but may cause life-threatening complications, particularly when located on the mitral valve. For such reason, surgical removal appears advisable, with low-risk procedures. Widespread use of multimodality imaging techniques will most likely increase the number of valvular blood cysts diagnosed also in adults.

Abstract
Cardiomyopathy refers to a spectrum of heterogeneous myocardial disorders characterized by morphological and structural alterations leading eventually to heart failure, by affecting cardiac filling and/or the cardiac systolic function. Heart transplantation is currently the gold standard surgical treatment for patients with heart failure, with a median survival in adults of 12 years according to international registries. However, the limited available donor pool does not allow its extensive employment. For this reason, mechanical circulatory supports are increasingly used, and in the short term are becoming as possible alternatives to heart transplantation, owing to improved technologies and increased biocompatibility. However, long-term outcomes of mechanical assist devices are still burdened with a high rate of adverse events. Conventional surgical treatments could be still considered as alternatives to heart replacement treatment when tailored both on patient clinical conditions and etiology of cardiac diseases. In particular, among patients affected by ischemic cardiomyopathy, coronary artery bypass grafting has proven to improve survival when associated to optimal medical treatment, and surgical ventricular restoration might be considered as a valid treatment in particular cases. Correction of functional mitral valve regurgitation by mitral annuloplasty, which aims to restore left ventricular geometry, has not demonstrated unambiguous results, and outcomes of this procedure are still controversial. Pericardial pathology becomes of surgical interest when it is responsible for a reduced filling capacity of the heart chambers, which can develop acutely (cardiac tamponade) or chronically (as in the case of constrictive pericarditis). This review focuses on the different surgical approaches that could be adopted to treat patients with heart failure and pericardial diseases.

Abstract
Maximal oxygen consumption (V̇O2max) is impaired in heart (HTx), kidney (KTx), and liver (LTx) transplanted recipients and the contribution of the cardiovascular, central, and peripheral (muscular) factors in affecting V̇O2max improvement after endurance training (ET) has never been quantified in these patients. ET protocols involving single leg cycling (SL) elicit larger improvements of the peripheral factors affecting O2 diffusion and utilization than the double leg (DL) cycling ET. Therefore, this study aimed to compare the effects of SL-ET vs DL-ET on V̇O2max. We determined the DL-V̇O2max and maximal cardiac output before and after 24 SL-ET vs DL-ET sessions on 33 patients (HTx = 13, KTx = 11 and LTx = 9). The DL-V̇O2max increased by 13.8% ± 8.7 (p < 0.001) following the SL-ET, due to a larger maximal O2 systemic extraction; meanwhile, V̇O2max in DL-ET increased by 18.6% ± 12.7 (p < 0.001) because of concomitant central and peripheral adaptations. We speculate that in transplanted recipients, SL-ET is as effective as DL-ET to improve V̇O2max and that the impaired peripheral O2 extraction and/or utilization play an important role in limiting V̇O2max in these types of patients. Novelty: SL-ET increases V̇O2max in transplanted recipients because of improved peripheral O2 extraction and/or utilization. SL-ET is as successful as DL-ET to improve the cardiorespiratory fitness in transplanted recipients. The model of V̇O2max limitation indicates the peripheral factors as a remarkable limitation to the V̇O2max in these patients.

Abstract
OBJECTIVES Patients with mechanical circulatory support bridged to a heart transplant (HTx) are at higher risk of postoperative graft dysfunction. In this subset, a mode of graft preservation that shortens graft ischaemia should be beneficial. METHODS The outcomes of 38 patients on mechanical circulatory support (extracorporeal life support, left ventricular assist device and biventricular assist device) who received a HTx between 2015 and 2020 were analysed according to the method of graft preservation: cold storage (CS) group, 24 (63%) or ex vivo perfusion (EVP) group, 14 (37%). RESULTS The median age was 57 (range 30-73) vs 64 (35-75) years (P = 0.10); 88% were men (P = 0.28); extracorporeal life support was more frequent in the CS group (54% vs 36%; P = 0.27) versus left ventricular and biventricular assist devices in the EVP group (46% vs 64%; P = 0.27). Clamping time was shorter in the EVP group (P < 0.001) and ischaemic time >4 h was higher in the CS group (P = 0.01). Thirty-day mortality was 13% (0-27%) in the CS group and 0% (P = 0.28) in the EVP group. A significantly lower primary graft failure [7% (0-23%) vs 42% (20-63%); P = 0.03] was observed in the EVP group. Survival at 1 year was 79 ± 8% (63-95%) in the CS group and 84 ± 10% (64-104%) in the EVP group (P = 0.95). CONCLUSIONS Our results support the use of ex vivo graft perfusion in patients on mechanical circulatory support as a bridge to a HTx. This technique, by shortening graft ischaemic time, seems to improve post-HTx outcomes.
