More recently, percutaneous mitral valve repair procedure (also called transcatheter end-to-end repair [TEER]), in which a clip is applied to approximate the anterior and posterior mitral leaflets, has been shown to reduce death and HF hospitalization in carefully selected patients with symptomatic HF despite optimal medical management and moderate to severe or severe mitral regurgitation with preserved LV size (end-systolic dimension ≤ 70 mm— 5).
