Abstract

Aims: Percutaneous edge-to-edge mitral valve repair with the MitraClip® was shown to be a safe and feasible alternative compared to conventional surgical mitral valve repair. We analyse the concept of the central clip and the predictors for the need of more than one MitraClip® in our high-risk surgical population with severe mitral regurgitation (MR). Methods and results: Patients with severe MR (3 or 4+) and high operative risk (as defined by logistic EuroSCORE) refused for conventional mitral valve repair were considered for MitraClip®. The procedure was performed under general anaesthesia with transoesophageal echocardiographic (TOE) guidance. Device success was defined as placement of one or more MitraClips® with a reduction of MR to ≤2+. Patients were followed up clinically and with TOE at one month and one year. From September 2009 to March 2012, 43 patients with severe MR with a mean age of 74.8±10.7 years (30 males, 13 females; mean logistic EuroSCORE 24.1±11, mean LVEF 47.5±18.5%; mean±SD) were treated. Median follow-up was 385 days (104-630; Q1-Q3). Device implantation success was 93%. All patients were treated following the central clip concept: 52.5% of MR was degenerative in aetiology and 47.5% was functional. The degree of MR was reduced from 3.6±0.4 to 1.4±0.6 (p
