We present the case of a patient with a paravalvular leak of mechanical prosthesis in aortic position. Due to a recent previous surgery, it was decided to perform a percutaneous repair to reduce perioperative risk, under an off-label indication using a device for ventricular septal defect closure, successful and without complications in the follow-up.

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%).

We present a 74-year-old female with a history of mechanical aortic and mitral valve implantation and non-Hodgkin lymphoma. She presented with right sided heart failure due to severe functional tricuspid regurgitation and was treated with transcatheter TricValve bicaval system implantation. However, this was complicated by a paravalvular leak of the inferior vena cava prosthesis.

Background: Paravalvular leak (PVL) remains a frequent complication of transcatheter aortic valve replacement (TAVR). The long-term consequences of mild PVL on outcomes have been debated. This study aimed to investigate the clinical and hemodynamic outcomes of mild PVL over a 2-year period.

Background: Critical gaps persist in clinical guidelines and resuscitation strategies for induction and maintenance phase peri-anesthetic cardiac arrest (IM-PACA), urgently necessitating exploration of feasible solutions during anesthesia induction and maintenance periods. This study evaluates a modified cardiopulmonary bypass (CPB) strategy for managing IM-PACA in valvular heart disease (VHD) surgical patients.
Methods: A retrospective analysis was performed on IM-PACA patients (n = 21) from 1,043 cardiac valve surgeries between March 2019 and January 2022 as the cardiac arrest-resuscitation group (CAR group).

: Transcatheter heart valve (THV) selection is challenging as self-expanding valves (SEVs) are associated with lower post-procedural mean aortic gradients, while balloon-expandable valves (BEVs) have lower rates of paravalvular leak (PVL) and permanent pacemaker implantation (PPI). We aimed to compare the 30-day and 1-year outcomes following Myval BEV (Meril Life Sciences, Vapi, Gujarat, India) and intra-annular Portico SEV (Abbott, St. Paul, MN, USA) implantation.
