RESUMO
OBJECTIVE: This study aimed to compare hemodynamic performances and clinical outcomes of patients with small aortic annulus (SAA) who underwent aortic valve replacement by means of sutureless aortic valve replacement (SUAVR) or transcatheter aortic valve implantation (TAVI). METHODS: From 2015 to 2020, 622 consecutive patients with SAA underwent either SUAVR or TAVI. Through a 1:1 propensity score matching analysis, two homogeneous groups of 146 patients were formed. Primary endpoint: all cause-death at 36 months. Secondary endpoints: incidence of moderate to severe patient-prosthesis mismatch (PPM) and incidence of major adverse cardiovascular and cerebrovascular events (MACCEs). RESULTS: All-cause death at three years was higher in the TAVI group (SUAVR 12.2% vs. TAVI 21.0%, P=0.058). Perioperatively, comparable hemodynamic performances were recorded in terms of indexed effective orifice area (SUAVR 1.12 ± 0.23 cm2/m2 vs. TAVI 1.17 ± 0.28 cm2/m2, P=0.265), mean transvalvular gradients (SUAVR 12.9 ± 5.3 mmHg vs. TAVI 12.2 ± 6.2 mmHg, P=0.332), and moderate-to-severe PPM (SUAVR 4.1% vs. TAVI 8.9%, P=0.096). TAVI group showed a higher cumulative incidence of MACCEs at 36 months (SUAVR 18.1% vs. TAVI 32.6%, P<0.001). Pacemaker implantation (PMI) and perivalvular leak ≥ 2 were significantly higher in TAVI group and identified as independent predictors of mortality (PMI: hazard ratio [HR] 3.05, 95% confidence interval [CI] 1.34-6.94, P=0.008; PPM: HR 2.72, 95% CI 1.25-5.94, P=0.012). CONCLUSION: In patients with SAA, SUAVR and TAVI showed comparable hemodynamic performances. Moreover, all-cause death and incidence of MACCEs at follow-up were significantly higher in TAVI group.

Background: EuroSCORE II (ES2) is a reliable tool for preoperative cardiac surgery mortality risk prediction; however, a patient's age, a surgical procedure's weight and the new devices available may cause its accuracy to drift. We sought to investigate ES2 performance related to the surgical risk and late mortality estimation in patients who underwent aortic valve replacement (AVR) with sutureless valves. Methods: Between 2012 and 2021, a total of 1126 patients with isolated aortic stenosis who underwent surgical AVR by means of sutureless valves were retrospectively collected from six European centers. Patients were stratified into three groups according to the EuroSCORE II risk classes (ES2 < 4%, ES2 4-8% and ES2 > 8%). The accuracy of ES2 in estimating mortality risk was assessed using the standardized mortality ratio (O/E ratio), ROC curves (AUC) and Hosmer-Lemeshow (HL) test for goodness-of-fit. Results: The overall observed mortality was 3.0% (predicted mortality ES2: 5.39%) with an observed/expected (O/E) ratio of 0.64 (confidential interval (CI): 0.49-0.89). In our population, ES2 showed a moderate discriminating power (AUC 0.65, 95%CI 0.56-0.72, p < 0.001; HL p = 0.798). Good accuracy was found in patients with ES2 < 4% (O/E ratio 0.54, 95%CI 0.23-1.20, AUC 0.75, p < 0.001, HL p = 0.999) and for patients with an age < 75 years (O/E ratio 0.98, 95%CI 0.45-1.96, AUC 0.76, p = 0.004, HL p = 0.762). Moderate discrimination was observed for ES2 in the estimation of long-term risk of mortality (AUC 0.64, 95%CI: 0.60-0.68, p < 0.001). Conclusions: EuroSCORE II showed good accuracy in patients with an age < 75 years and patients with ES2 < 4%, while overestimating risk in the other subgroups. A recalibration of the model should be taken into account based on the complexity of actual patients and impact of new technologies.
RESUMO
BACKGROUND: The aim of this study is to report the preliminary real-word clinical and hemodynamic performance from the MANTRA study in patients undergoing aortic valve replacement with Perceval PLUS sutureless valve. METHODS: MANTRA is an ongoing "umbrella" prospective, multi-center, international post-market study to collect real-life safety and performance data on Corcym devices (Corcym S.r.l, Saluggia, Italy). Clinical and echocardiographic outcomes were collected preoperatively, at discharge and at each follow up. KCCQ-12 and EQ-5D-5L quality of life questionnaires were collected preoperatively and at 30-days. RESULTS: A total of 328 patients underwent aortic valve replacement with Perceval PLUS in 29 International institutions. Patients were enrolled from July 2021 to October 2023 and enrollment is still ongoing. Mean age was 71.9 ± 6.4 years, mean EuroSCORE II was 2.9 ± 3.9. Minimally invasive approach was performed in 44.2% (145/328) of patients; concomitant procedures were done in 40.8% (134/328) of cases. Thirty-day mortality was 1.8% (6/328) and no re-interventions were reported. Pacemaker implant was required in 4.0% (13/328) of the patients. The assessment of the functional status demonstrated marked and stable improvement in NYHA class in most patients at 30-day follow-up, with significant increase of KCCQ-12 summary score (from 58.8 ± 23.0 to 71.8 ± 22.1, p < 0.0001) and EQ-5D-5L VAS score (from 64.5 ± 20.4 to 72.6 ± 17.5, p < 0.0001). Mean pressure gradient decreased from 46.2 ± 17.3 mmHg to 10.1 ± 4.7 mmHg at 30-day follow-up. Low or no incidence of moderate-to-severe paravalvular or central leak was reported. CONCLUSIONS: Preliminary results demonstrate good clinical outcomes and significant improvement of Quality of Life at 30-days, excellent early hemodynamic performance within patient implanted with Perceval PLUS. TRIAL REGISTRATION: The MANTRA study has been registered in ClinicalTrials.gov (NCT05002543, Initial release 26 July 2021).

BACKGROUND: Infective endocarditis (IE) is marked by a heightened risk of embolic events (EEs), uncontrolled infection, or heart failure (HF). METHODS: Patients with IE and surgical indication were enrolled from October 2015 to December 2018. The primary endpoint consisted of a composite of major adverse events (MAEs) including all-cause death, hospitalizations, and IE relapses. The secondary endpoint was all-cause death. RESULTS: A total of 102 patients (66 ± 14 years) were enrolled: 50% with IE on prosthesis, 33% with IE-associated heart failure (IE-aHF), and 38.2% with EEs. IE-aHF and EEs were independently associated with MAEs (HR 1.9, 95% CI 1.1-3.4, p = 0.03 and HR 2.1, 95% CI 1.2-3.6, p = 0.01, respectively) and Kaplan-Meier survival curves confirmed a strong difference in MAE-free survival of patients with EEs and IE-aHF (p < 0.01 for both). IE-aHF (HR 4.3, 95% CI 1.4-13, p < 0.01), CRP at admission (HR 5.6, 95% CI 1.4-22.2, p = 0.01), LVEF (HR 0.9, 95% CI 0.9-1, p < 0.05), abscess (HR 3.5, 95% CI 1.2-10.6, p < 0.05), and prosthetic detachment (HR 4.6, 95% CI 1.5-14.1, p < 0.01) were independently associated with the all-cause death endpoint. CONCLUSIONS: IE-aHF and EEs were independently associated with MAEs. IE-aHF was also independently associated with the secondary endpoint.
RESUMO
BACKGROUND: Sutureless aortic bioprostheses are increasingly being used to provide shorter cross-clamp time and facilitate minimally invasive aortic valve replacement. As the use of sutureless valves has increased over the past decade, we begin to encounter their degeneration. We describe clinical outcomes and technical aspects in patients with degenerated sutureless Perceval (CorCym, Italy) aortic bioprosthesis treated with valve-in-valve transcatheter aortic valve replacement (VIV-TAVR). METHODS: Between March 2011 and March 2023, 1310 patients underwent aortic valve replacement (AVR) with Perceval bioprosthesis implantation. Severe bioprosthesis degeneration treated with VIV-TAVR occurred in 32 patients with a mean of 6.4 ± 1.9 years (range: 2-10 years) after first implantation. Mean EuroSCORE II was 9.5 ± 6.4% (range: 1.9-35.1%). RESULTS: Thirty of thirty-two (94%) VIV-TAVR were performed via transfemoral and two (6%) via transapical approach. Vascular complications occurred in two patients (6%), and mean hospital stay was 4.6 ± 2.4 days. At mean follow-up of 16.7 ± 15.2 months (range: 1-50 months), survival was 100%, and mean transvalvular pressure gradient was 18.7 ± 5.3 mmHg. CONCLUSION: VIV-TAVR is a useful option for degenerated Perceval and appears safe and effective. This procedure is associated with good clinical results and excellent hemodynamic performance in our largest single-center experience.
RESUMO
BACKGROUND: Recent randomized controlled trials showed comparable short-term outcomes of transcatheter aortic valve implantation versus surgical aortic valve replacement in intermediate and low-risk patients. However, independent studies comparing transcatheter aortic valve implantation results versus surgical aortic valve replacement at 5 years showed worsening outcomes in patients treated with transcatheter aortic valve implantation. The aim of this study was to analyze mid- to long-term outcomes of patients with isolated aortic stenosis and an intermediate-risk profile who underwent aortic valve replacement using a sutureless valve versus transcatheter aortic valve implantation. METHODS: This retrospective multi-institutional European study investigated 2,123 consecutive patients with isolated aortic stenosis at intermediate risk profile treated with sutureless aortic valve replacement (824 patients) or transcatheter aortic valve implantation (1,299 patients) from 2013 to 2020. After 1:1 propensity score matching, 2 balanced groups of 517 patients were obtained. Primary endpoints were as follows: 30 days, late all-cause, and cardiac-related mortality. Secondary endpoints included major adverse cardiocerebrovascular events (all-cause death, stroke/transient ischemic attack, endocarditis, reoperation, permanent pacemaker implantation, and paravalvular leak grade ≥2). RESULTS: Median follow-up was 4.3 years (interquartile range 1.1-7.4 years). Primary endpoints were as follows-30-day mortality sutureless aortic valve replacement: 2.13% versus transcatheter aortic valve implantation: 4.64% (P = .026), all-cause mortality sutureless aortic valve replacement: 36.7% ± 7.8% vs transcatheter aortic valve implantation: 41.8% ± 8.2% (P = .023), and cardiac-related mortality sutureless aortic valve replacement: 10.2% ± 2.8% vs transcatheter aortic valve implantation: 19.2% ± 3.5%;(P = .00043) at follow-up. Secondary endpoints were as follows-major adverse cardiocerebrovascular events in the sutureless aortic valve replacement group: 47.2% ± 9.0% versus transcatheter aortic valve implantation: 57.3% ± 7.5% (P < .001). In particular, the incidence of permanent pacemaker implantation (sutureless aortic valve replacement: 6.38% versus transcatheter aortic valve implantation: 11.8% [P = .002]) and paravalvular leak ≥2 (sutureless aortic valve replacement: 0.97% versus transcatheter aortic valve implantation: 4.84% [P = .001]) was significantly higher in transcatheter aortic valve implantation group. At Multivariable Cox regression analysis, paravalvular leak ≥2 (hazard ratio: 1.63%; 95% confidence interval: 1.06-2.53, P = .042) and permanent pacemaker implantation (hazard ratio: 1.49%; 95% confidence interval: 1.02-2.20, P = .039) were identified as predictors of mortality. CONCLUSION: Sutureless aortic valve replacement showed a significantly lower incidence of all-cause mortality, cardiac-related death, permanent pacemaker implantation, and paravalvular leak than transcatheter aortic valve implantation. Moreover, permanent pacemaker implantation and paravalvular leak negatively affected survival in patients treated for isolated aortic stenosis.

OBJECTIVES: Perceval sutureless valve has been in clinical use for >15 years. The aim of this study is to report the real-word clinical and haemodynamic performance from the SURE-aortic valve replacement international prospective registry in patients who underwent aortic valve replacement with Perceval valve. METHODS: From 2011 to 2021, patients from 55 institutions received a Perceval valve. Postoperative, follow-up, and echocardiographic outcomes were analysed. RESULTS: A total of 1652 patients were included; mean age was 75.3 ± 7.0 years (53.9% female); mean EuroSCORE II was 4.1 ± 6.3. Minimally invasive approach was performed in 45.3% of patients; concomitant procedures were done in 35.9% of cases. Within 30 days, 0.3 and 0.7% valve-related reinterventions were reported. Transient ischaemic attack, disabling and non-disabling strokes were limited (0.4%, 0.4% and 0.7%, respectively). Pacemaker implant was required in 5.7% of patients. Intra-prosthetic regurgitation ≥2 was present in 0.2% of cases, while paravalvular leak ≥2 in only 0.1%. At a maximum follow-up of 8 years, 1.9% of cardiovascular deaths and 0.8% of valve-related reintervention occurred. Among the 10 cases of structural valve deterioration (mean 5.6 ± 1.4 years after implant; range: 2.6-7.3 years), 9 were treated with a transcatheter vale-in-valve implantation and 1 with explant. Mean pressure gradient decreased from 45.8 ± 16.5 mmHg preoperatively to 13.3 ± 5.2 mmHg at discharge and remained stable during follow-up. CONCLUSIONS: This experience represents the largest prospective real-world cohort of patients treated with Perceval showing that Perceval is a safe and effective alternative to conventional surgical aortic valve replacement, providing favourable clinical and haemodynamic results also at mid-term follow-up.
RESUMO
Background: Frailty is highly common in older patients (pts) undergoing transcatheter aortic valve replacement (TAVR), and it is associated with poor outcomes. The selection of patients who can benefit from this procedure is necessary and challenging. The aim of the present study is to evaluate outcomes in older severe aortic valve stenosis (AS) pts, selected by a multidisciplinary approach for surgical, clinical, and geriatric risk and referred to treatment, according to frailty levels. Methods: A total of 109 pts (83 ± 5 years; females, 68%) with AS were classified by Fried's score in pre-frail, early frail, and frail and underwent surgical aortic valve replacement SAVR/TAVR, balloon aortic valvuloplasty, or medical therapy. We evaluated geriatric, clinical, and surgical features and detected periprocedural complications. The outcome was all-cause mortality. Results: Increasing frailty was associated with the worst clinical, surgical, geriatric conditions. By using Kaplan-Meier analysis, the survival rate was higher in pre-frail and TAVR groups (p < 0.001) (median follow-up = 20 months). By using the Cox regression model, frailty (p = 0.004), heart failure (p = 0.007), EF% (p = 0.043), albumin (p = 0.018) were associated with all-cause mortality. Conclusions: According to tailored frailty management, elderly AS pts with early frailty levels seem to be the most suitable candidates for TAVR/SAVR for positive outcomes because advanced frailty would make each treatment futile or palliative.
RESUMO
AIMS: We describe long-term clinical and echocardiographic outcomes in the largest single-centre cohort of patients who underwent aortic valve replacement (AVR) with sutureless Perceval (CorCym, Italy) bioprosthesis. METHODS: Between March 2011 and March 2021, 1157 patients underwent AVR with Perceval bioprosthesis implantation. Mean age was 77â±â6âyears (range: 46-89âyears) and mean EuroSCORE II was 6.7â±â3.2% (range: 1.7-14.2%). Concomitant procedures were performed in 266 patients (23%). RESULTS: Thirty-day mortality was 1.38% (16/1157). Eight hundred and twenty of 891 (92%) isolated AVRs underwent minimally invasive surgery with a ministernotomy ( n â=â196) or right minithoracotomy ( n â=â624) approach. Cardiopulmonary bypass and aortic cross-clamp times were 81.1â±â24.3 and 50.6â±â11.7âmin for isolated AVR and 144.5â±â34.7 and 96.4â±â21.6âmin for combined procedures. At mean follow-up of 53.08â±â6.7âmonths (range: 1-120.5âmonths), survival was 96.5% and mean transvalvular pressure gradient was 13.7â±â5.8âmmHg. Left ventricular mass decreased from 152.8 to 116.1âg/m 2 ( P â<â0.001) and moderate paravalvular leakage occurred in three patients without haemolysis not requiring any treatment. Freedom from reoperation was 97.6%. Eight patients required surgical reintervention and 19 patients transcatheter valve-in-valve procedure for structural prosthesis degeneration at a mean of 5.6âyears after first operation (range: 2-9âyears). CONCLUSION: AVR with a Perceval bioprosthesis is associated with good clinical results and excellent haemodynamic performance in our 10-year experience. Structural degeneration rate of Perceval is comparable with other bioprosthetic aortic valves. Sutureless technology may reduce operative time especially in combined procedures and enable minimally invasive AVR.

Aim: Hamartoma of mature cardiomyocytes is a rare tumor and the present case shows a complex diagnostic pathway to understand its nature and treatment options in a young patient. The myocardial bridge was also part of the clinical evaluation discovered during the diagnostic workout. Methods and results: A 27-year-old woman with atypical chest pain and a normal electrocardiogram received the diagnosis of neoformation of the interventricular septum with 18F-fluorodeoxyglucose (18F-FDG) uptake, and evidence of myocardial bridging on coronary angiography. On suspicion of malignancy, coronary unroofing and surgical biopsy was performed. The final diagnosis was hamartoma of mature cardiomyocytes. Conclusion: This case offers great insight into medical reasoning and decision-making process. Given the history of chest pain, the patient was evaluated for possible ischemic, embolic, or vascular causes. Given a left ventricular wall thickness ≥15 mm, hypertrophic cardiomyopathy (HCM) should always be suspected; nuclear magnetic resonance imaging is essential to distinguish between HCM. The magnetic resonance imaging is also critical in distinguishing HCM itself from tumoral phenocopies. To rule out a neoplastic process, 18F-FDG positron emission tomography (PET) was used. A surgical biopsy was performed, and the final diagnosis was completed after the immune-histochemistry study. A myocardial bridge was found during preoperative coronagraphy and was treated accordingly.
RESUMO
OBJECTIVES: The role of the underlying etiology in isolated tricuspid valve surgery has not been investigated extensively in current literature. Aim of this study was to analyse outcomes of patients undergoing surgery due to endocarditis compared to other pathologies. METHODS: The SURTRI study is a multicenter study enrolling adult patients who underwent isolated tricuspid valve surgery (n = 406, 55 ± 16 y.o.; 56% female) at 13 international sites. Propensity weighted analysis was performed to compare groups (IE group n = 107 vs Not-IE group n = 299). RESULTS: No difference was found regarding the 30-day mortality (Group IE: 2.8% vs Group Not-IE = 6.8%; OR = 0.45) and major adverse events. Weighted cumulative incidence of cardiac death was significantly higher for patients with endocarditis (p = 0.01). The composite endpoint of cardiac death and reoperation at 6 years was reduced in the Group IE (63.2 ± 6.8% vs 78.9 ± 3.1%; p = 0.022). Repair strategy resulted in an increased late survival even in IE cases. CONCLUSIONS: Data from SURTRI study report acceptable 30-day results but significantly reduced late survival in the setting of endocarditis of the tricuspid valve. Multi-disciplinary approach, repair strategy and earlier treatment may improve outcomes.

OBJECTIVES: The aim of this study was to investigate the need for postoperative permanent pacemaker implantation (PPI) following sutureless and rapid-deployment aortic valve replacement (SuRD-AVR) in the context of a progress report from a large multicenter international registry (SURD-IR). METHODS: We retrospectively analyzed 4,166 patients who underwent SuRD-AVR between 2008 and 2019. The primary outcome was the need for PPI before discharge. The study population was analyzed separately according to the implanted prostheses (Su cohort and RD cohort). Each cohort was divided into two groups based on the operation date: an early group ("EG" = 2008-2016) and a late group ("LG" = 2017-2019). RESULTS: The rate of PPI decreased significantly in the Su cohort over time (EG = 10.8% vs LG = 6.3%, p < 0.001). In the Su cohort, a decrease in age, risk profile, and incidence of bicuspid aortic valve, increased use of anterior right thoracotomy, reduction of cardiopulmonary bypass time and of associated procedures, and more frequent use of smaller prostheses were observed over time. In the RD cohort, the rate of PPI was stable over time (EG = 8.8% vs LG = 9.3%, p = 0.8). In this cohort, a younger age, lower risk profile, and higher incidence of concomitant septal myectomy were observed over time. CONCLUSION: Our analysis showed a significant decrease in the PPI rate in patients who underwent Su-AVR over time. Patient selection as well as surgical improvements and a more accurate sizing could be correlated with this phenomenon. The RD cohort revealed no significant differences either in patient's characteristics or in PPI rate between the two time periods.

Patients with previously diagnosed HF are at greater risk for subsequent morbidity and mortality when hospitalized for an Acute Myocardial Infarction (AMI). The purpose of our study was to describe the time trend of the incidence of emergent CABG in patients with and without HF, the clinical characteristics, outcomes, and the risk factors for mortality of surgical revascularization in the short and medium term. This was a single-center retrospective observational study of patients who underwent isolated emergency CABG from January 2009 to January 2020. A propensity-score matching analysis yielded two comparable groups (n = 430) of patients without (n = 215) and with (n = 215) heart failure. In-hospital mortality did not differ in the two groups (2.8%; p > 0.9); the patients with heart failure presented more frequently with cardiogenic shock, and there was an association with mortality and mechanical circulatory support (OR 16.7−95% CI 3.31−140; p = 0.002) and postoperative acute renal failure (OR 15.9−95% CI 0.66−203; p = 0.036). In the early- and mid-term, heart failure and NSTEMI were associated with mortality (HR 3.47−95% CI 1.15−10.5; p = 0.028), along with age (HR 1.28−95% CI 1.21−1.36; p < 0.001). Surgical revascularization offers an excellent solution for patients with acute coronary syndrome, leading to a good immediate prognosis even in those with chronic heart failure.
RESUMO
BACKGROUND: Venous thromboembolism represents the third most frequent acute cardiovascular syndrome worldwide. Its clinical manifestations are deep vein thrombosis and/or pulmonary embolism. Despite a considerable mortality, diagnosis is often missed. CASE PRESENTATION: We report the management of a female patient with high-risk pulmonary thromboembolism treated initially with thromboaspiration, complicated by embolus jailing in a patent foramen ovale. In this situation, left cardiac chambers and systemic circulation were jeopardized by this floating embolus. CONCLUSIONS: High-risk pulmonary embolism requires reperfusion strategy but sometimes mechanical thromboaspiration may be not fully successful; transesophageal echocardiography led to a prompt diagnosis of this unexpected finding; in this very particular case, open surgery represented a bail-out procedure to avoid cerebral and systemic embolism.

Introduction: Primary mitral valve regurgitation (MR) results from degeneration of mitral valve apparatus. Mechanisms leading to incomplete postoperative left ventricular (LV) reverse remodeling (Rev-Rem) despite timely and successful surgical mitral valve repair (MVR) remain unknown. Plasma exosomes (pEXOs) are smallest nanovesicles exerting early postoperative cardioprotection. We hypothesized that late plasma exosomal microRNAs (miRs) contribute to Rev-Rem during the late postoperative period. Methods: Primary MR patients (n = 19; age, 45-71 years) underwent cardiac magnetic resonance imaging and blood sampling before (T0) and 6 months after (T1) MVR. The postoperative LV Rev-Rem was assessed in terms of a decrease in LV end-diastolic volume and patients were stratified into high (HiR-REM) and low (LoR-REM) LV Rev-Rem subgroups. Isolated pEXOs were quantified by nanoparticle tracking analysis. Exosomal microRNA (miR)-1, -21-5p, -133a, and -208a levels were measured by RT-qPCR. Anti-hypertrophic effects of pEXOs were tested in HL-1 cardiomyocytes cultured with angiotensin II (AngII, 1 µM for 48 h). Results: Surgery zeroed out volume regurgitation in all patients. Although preoperative pEXOs were similar in both groups, pEXO levels increased after MVR in HiR-REM patients (+0.75-fold, p = 0.016), who showed lower cardiac mass index (-11%, p = 0.032). Postoperative exosomal miR-21-5p values of HiR-REM patients were higher than other groups (p < 0.05). In vitro, T1-pEXOs isolated from LoR-REM patients boosted the AngII-induced cardiomyocyte hypertrophy, but not postoperative exosomes of HiR-REM. This adaptive effect was counteracted by miR-21-5p inhibition. Summary/Conclusion: High levels of miR-21-5p-enriched pEXOs during the late postoperative period depict higher LV Rev-Rem after MVR. miR-21-5p-enriched pEXOs may be helpful to predict and to treat incomplete LV Rev-Rem after successful early surgical MVR.
RESUMO
OBJECTIVES: To compare procedural and in-hospital outcomes of patients undergoing sutureless (Perceval, Livanova PLC, London, UK) and rapid deployment (Intuity Elite, Edwards Lifesciences, Irvine, CA, USA) aortic valve replacement (group 1) versus sutured aortic valve replacement (group 2). METHODS: Patients receiving isolated aortic valve replacement between 2014 and 2020 were analysed using data from the Sutureless and Rapid Deployment International Registry. Patients in group 1 and group 2 were propensity-score matched in a 1:1 ratio. RESULTS: A total of 7708 patients were included in the study. After matching, 2 groups of 2643 each were created. Patients in group 1 were more likely to undergo minimally invasive approaches and were associated with shorter operative times when compared with group 2. Overall in-hospital mortality was similar between groups. While an increased risk of stroke was observed in group 1 in the first study period (2014-2016; relative risk 3.76, P < 0.001), no difference was found in more recent year period (relative risk 1.66, P = 0.08; P for heterogeneity 0.003). Group 1 was associated with reduced rates of postoperative low cardiac output syndrome, atrial fibrillation and mild aortic regurgitation. New pacemaker implant was three-fold higher in group 1. CONCLUSIONS: Our findings showed significant differences in procedural and clinical outcomes between the study groups. These results suggest that sutureless and rapid deployment aortic valve replacement should be considered as part of a comprehensive valve programme. The knowledge of the respective post-aortic valve replacement benefits for different valve technologies may result in patient-tailored valve selection with improved clinical outcomes.

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.
