Evolution of Untreated Moderate Mitral Regurgitation After Transcatheter Aortic Valve Implantation.

ABSTRACT: Background and Objectives: Associated mitral regurgitation (MR) is frequently observed during transcatheter aortic valve implantation (TAVI). The progression of moderate MR remains undetermined, given uncertain clinical significance and natural history. This study aims to assess the evolution of moderate MR following TAVI. Materials and Methods: Between 2018 and 2023, 1476 patients underwent TAVI. We excluded those with previous aortic or mitral valve interventions, endocarditis, concomitant percutaneous coronary intervention, or emergent procedures. Patients with severe aortic or tricuspid regurgitation or significant mitral stenosis were excluded. Ultimately, only patients with moderate MR were included, resulting in a final population of 154 patients. Results: Mean
