Operator Experience Matters for Transcatheter Mitral Valve Repair

A registry analysis demonstrated an improvement in procedure success after an interventionalist's first 50 cases.

Transcatheter mitral valve repair (TMVr) with MitraClip was FDA-approved in 2013. To assess the association between operator experience and procedural outcomes, investigators analyzed the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy (TVT) Registry involving 14,923 commercial procedures performed by 562 operators at 290 U.S. hospitals between 2013 and 2018.

The study population had a median age of 81 and a high prevalence of comorbid conditions. In stepwise fashion across levels of operator experience (1–25 cases, 26–50 cases, and >50 cases), there were decreases in procedure time (145, 118, and 99 minutes, respectively) and complications (10%, 8%, and 7%) and greater optimal procedural success (64%,…
