Mitral valve annuloplasty with Carpentier-Edwards physio ring: mid-term results.
The mid-term results of mitral valve repair with the Carpentier-Edwards Physio annuloplasty ring were assessed in 97 consecutive patients in a single tertiary-referral cardiothoracic surgical center. The mean follow-up time was 3.9 years (range, 1 month to 8.9 years). Most patients were in functional class II and III before the operation. Ejection fraction was < 40% in 8 patients. Causes of mitral regurgitation included degenerative disease (66%), infective endocarditis (13.4%), rheumatic disease (10.3%), and ischemic heart disease (9.3%). Thirty-day mortality was 2.1%. Actuarial survival and freedom from re-operation at 8 years were 91% and 90.8%, respectively. The only significant risk factor for re-operation was residual mitral regurgitation. Four patients suffered thromboembolic complications, giving an overall event-free survival of 93% +/- 3.7% during the follow-up period. The Carpentier-Edwards Physio ring provides safe and effective repair of mitral regurgitation on mid-term follow-up.
