Severe Mitral Regurgitation Secondary to Dehiscence of a Mitral Annuloplasty Ring Shown on 3D Transoesophageal Echocardiography

Abstract

T and a half years previously a 72 year-old man had undergone mitral valve repair and insertion of a 28mm-Cosgrove annuloplasty ring for severe symptomatic mitral regurgitation (MR).
