Feasibility of Myxomatous Mitral Valve Repair Using Direct Leaflet and Chordal Radiofrequency Ablation

摘要

ObjectiveMinimally invasive repair of mitral valve prolapse (MVP) causing severe mitral regurgitation (MR) should reduce mitral regurgitation and have chronic durability. Our ex-vivo, acute in-vivo, and chronic in-vivo studies suggest that direct application of radiofrequency ablation (RFA) to mitral leaflets and chordae can effect these repair goals to decrease MR.
