Hemodynamic and clinical response to transseptal mitral valve‐in‐valve and valve‐in‐ring

Objective To understand the clinical and hemodynamic response of patients with stenotic versus regurgitant prosthetic mitral valve degeneration to transseptal transcatheter mitral valve‐in‐ring/‐valve replacement (TMVR). Background Patients with prosthetic mitral valve repair/replacement failure frequently present high‐risk surgical challenges. TMVR has been employed as an alternative to surgery. Methods Forty‐four patients with...
