Paravalvular leak is a common complication after surgical mitral valve replacement. Surgically implanted prosthetic valves are complicated with paravalvular leaks in 17%. Surgical closure of paravalvular leaks is the most common therapy for these defects. Percutaneous closure is an alternative to repeat surgery for a selected high-risk population. We present a case of a patient who developed severe haemolytic anaemia and secondary renal failure after partially successful percutaneous closure of paravalvular leakage of a prosthetic mitral valve. The assumption is that the combination of a metallic foreign body and high shear stress caused haemolysis by damaging red blood cells.

Long-Term Clinical Impact of Paravalvular Leak Following Transcatheter Aortic Valve Implantation.

Paravalvular leak (PVL) was initially recognized as one of the most common complications after transcatheter aortic valve implantation (TAVI) and has been linked to adverse clinical outcomes, including mortality. This study aims to assess the long-term clinical effects of PVL in patients undergoing TAVI with the latest generation of transcatheter aortic valves, as part of the national observational prospective multicenter study OBSERVANT II. OBSERVANT II included all consecutive patients with severe aortic stenosis who underwent TAVI across 28 Italian centers from December 2016 to September 2018.

Background: Patients with low-flow, low-gradient (LFLG) aortic stenosis (AS) have precarious hemodynamics and are a fragile population for intervention. Quantification of aortic valve calcification (AVC) severity is a critical component of the evaluation for transcatheter aortic valve replacement (TAVR); this study aims to further clarify its utility for risk stratification in LFLG AS.
Methods: This retrospective study evaluated 467 patients with LFLG AS undergoing TAVR at a large quaternary-care hospital from January 2019 to December 2021.

Background: Aortic stenosis (AS) remains a prevalent and serious global health concern, exacerbated by an aging population worldwide. This valvular disease, when symptomatic and without appropriate intervention, severe AS can drastically reduce life expectancy. In our systematic review and -analysis, we aim to synthesize available evidence to guide clinical decision-making by comparing the performance of TAVR and SAVR, specifically in patients with severe AS and a small aortic annulus.
