Objective: Minimally invasive aortic valve replacement (MIAVR) and transcatheter aortic valve replacement (TAVR) represent less-invasive alternatives to conventional surgical aortic valve replacement. In contrast to Society of Thoracic Surgeons (STS) Database data revealing <10% of all surgical aortic valve replacement procedures are performed via a minimally invasive approach, our center performs a high volume of MIAVR procedures. This propensity-score matched study aims to compare the outcomes of MIAVR versus TAVR in low-risk patients (STS Predicted Risk of Mortality <4%).

The novel Navitor intra-annular self-expandable transcatheter aortic valve prosthesis is designed to improve coronary access, reduce paravalvular leaks, and enhance hemodynamic performance. Comparative data with the established Evolut platform (R, Pro, FX) are still lacking. This study aimed to evaluate the short-term clinical outcomes of Navitor (NAV) versus Evolut transcatheter heart valves.

Background: Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of severe aortic valve stenosis (AS). Balloon post-dilatation (PD) remains an important procedural step to optimize valve function by resolving incomplete valve expansion, which may lead to paravalvular regurgitation and other potentially adverse effects. There are only limited data on the predictors, incidence, and clinical impact of PD during TAVI.

Background: Transcatheter pulmonary valve replacement (TPVR) has emerged as a less invasive alternative to surgical pulmonary valve replacement for patients with right ventricular outflow tract (RVOT) dysfunction, such is especially important for those individuals whom had previous cardiac surgical procedures. Recently, three-dimensional (3D) printing and finite element (FE) computational simulation technologies have been employed to enhance preoperative planning processes; however, their effectiveness and clinical significance remain to be fully validated. This systematic review aims to describe the applications and potential impacts of 3D printing and FE simulation technologies for TPVR in clinical practice.

Evidence suggests that even mild-to-moderate paravalvular regurgitation (PVR) following transcatheter aortic valve implantation (TAVI) is associated with adverse outcomes. We directly compared the diagnostic performance and predictive value of invasive (hemodynamic) versus noninvasive (echocardiographic) assessments of PVR. Additionally, we explored the effectiveness of a comprehensive integrated approach that combines both methodologies to accurately identify and predict the clinical consequences of PVR.
