PG - 1034-40 LID - 10.1136/heartjnl-2012-303105 [doi] AB - BACKGROUND: Percutaneous mitral valve repair (MVR) using the MitraClip system has become a valid alternative for patients with severe mitral regurgitation (MR) and high operative risk. OBJECTIVE: To identify clinical and periprocedural factors that may have an impact on clinical outcome. DESIGN: Multi-centre longitudinal cohort study. SETTING: Tertiary referral centres. PATIENTS: Here we report on the first 100 consecutive patients treated with percutaneous MVR in Switzerland between March 2009 and April 2011. All of them had moderate-severe (3+) or severe (4+) MR, and 62% had functional MR. 82% of the patients were in New York Heart Association (NYHA) class III/IV, mean left ventricular ejection fraction was 48% and the median European System for Cardiac Operative Risk Evaluation was 16.9%. INTERVENTIONS: MitraClip implantation performed under echocardiographic and fluoroscopic guidance in general anaesthesia. MAIN OUTCOME MEASURES: Clinical, echocardiographic and procedural data were prospectively collected. RESULTS: Acute procedural success (APS, defined as successful clip implantation with residual MR grade
