Purpose: Important comorbid conditions in elderly patients referred for aortic valve replacement require alternative treatment options with possible reduction of the extracorporeal circuit time and reliable hemodynamic features. We report on clinical experiences with the sutureless, nitinol-stented 3f Enable (ATS Medical, Minneapolis, MN) aortic valve prosthesis in 32 patients.
Description: The procedure was performed using cardiopulmonary bypass with cardioplegic arrest. After resection of the stenotic aortic valve and debridement of the annulus, the valve was inserted and released. Mean age was 78 +/- 3; mean logistic Euroscore was 13.7. Concomitant procedures were mitral valve and tricuspid valve repair (n = 1), coronary artery bypass graft (n = 9), and subvalvular myectomy (n = 3).
Evaluation: Implantation of the valve required 9 +/- 5 minutes. Cardiopulmonary bypass and aortic cross-clamp time were 87 +/- 16 and 55 +/- 11 minutes for stand-alone procedures. Combined procedures required 126 +/- 42 and 84 +/- 28 minutes, respectively. Two patients were abandoned intraoperatively and converted to standard procedures due to misalignment of the valve. In the other 30 patients, no paravalvular leakage was detected. The transvalvular gradient at discharge was 9 +/- 6 mm Hg (mean) and 18 +/- 9 mm Hg (peak). Six months after surgery, gradients were 10 +/- 4 mm Hg (mean) and 18 +/- 6 mm Hg (peak).
Conclusions: Sutureless valve implantation is feasible and safe with the 3f Enable (ATS Medical) bioprosthesis. Reduction of cardiopulmonary bypass and aortic cross-clamp time seems to be possible with increasing experience. Hemodynamic data are promising with low gradients at discharge and after 6 months.

Background: Triglyceride-glucose-BMI (TyG-BMI) index is a surrogate marker of insulin resistance and an important predictor of cardiovascular disease. However, the predictive value of TyG-BMI index in the progression of non-severe aortic stenosis (AS) is still unclear.
Methods: The present retrospective observational study was conducted using patient data from Aortic valve diseases RISk facTOr assessmenT andprognosis modeL construction (ARISTOTLE).

Research establishing factors associated with duration of mechanical ventilation after Tetralogy of Fallot repair, is mainly based on population presenting at early infancy. There are fewer reports regarding repair after infancy, during childhood and preadolescence. To compare two groups of late TOF repair based on post-operative invasive mechanical ventilation duration and explore associations with pre-operative clinical markers of severity of right ventricular outflow tract obstruction.

Background: The optimal timing for percutaneous coronary intervention (PCI) in patients undergoing transcatheter aortic valve replacement (TAVR) is debatable.
Objectives: The aim of this study was to compare outcomes based on the timing of PCI in stable coronary artery disease patients undergoing TAVR.
Methods: Leveraging the STS/ACC TVT Registry and Medicare Linkage, we analyzed patients with stable coronary artery disease undergoing PCI and TAVR between 2015 and 2023 using the SAPIEN 3 balloon-expandable valve platform.

Background: The prevalence of coronary artery disease in patients undergoing transcatheter aortic valve replacement (TAVR) is high. Treatment of a coronary events (CE) after TAVR can be technically challenging.
Objectives: The authors sought to assess the incidence and prognostic impact of CE after TAVR.
