Outcomes of repeat mitral valve replacement in patients with prior mitral surgery: A benchmark for transcatheter approaches

A re-MVR is a high-risk operation, but in carefully selected patients such as our benchmark population, it can be performed with acceptable results. Patients undergoing pMVP also have better long-term survival compared with patients undergoing pMVR. These results will serve as a benchmark for transcatheter mitral valve-in-valve/ring replacement.
