Current strategies of mitral valve repair Spiegelstein D; Ghosh P; Sternik L; Tager S; Shinfeld A; Raanani EIsr Med Assoc J 2007[Apr]; 9 (4): 303-9BACKGROUND: During the last decade new surgical techniques for mitral valve repair were developed. We have been using those techniques in order to widen the spectrum of patients eligible for MV repair. OBJECTIVES: To assess the operative and mid-term results a wide variety of surgical techniques. METHODS: From January 2004 through December 2006, 213 patients underwent MV repair in our institution. Valve pathology was degenerative in 123 patients (58%), ischemic in 37 (17%), showed annular dilatation in 25 (12%), endocarditis in 16 (8%), was rheumatic in 13 (6%), and due to other causes in 14 (7%). Preoperative New York Heart Association score was 2.35 +/- 0.85 and ejection fraction 53 +/- 12%. Isolated MV repair was performed in 90 patients (42%) and 158 concomitant procedures were done in 123 patients (58%). A wide variety of surgical techniques was used in order to increase the number of repairs compared to valve replacement. RESULTS: There were 7 in-hospital deaths (3.3%). NYHA class improved from 2.19 +/- 0.85 to 1.4 +/- 0.6, and freedom from reoperation was 100%. Echocardiography follow-up of patients with degenerative MV revealed that 93% of the patients (115/123) were free of mitral regurgitation greater than 2+ grade. In patients operated by a minimal invasive approach there were no conversions to stemotomy, no late deaths, none required reoperation, and 96% were free of MR greater than 2+ grade. The use of multiple surgical techniques enabled the repair of more than 80% of pure MR cases. CONCLUSIONS: MV repair provides good perioperative and mid-term results, and supports the preference for MV repair over replacement, when feasible. Multiple valve repair techniques tailored to different pathologies increases the feasibility of mitral repair.|*Practice Guidelines as Topic[MESH]|Adolescent[MESH]|Adult[MESH]|Aged[MESH]|Aged, 80 and over[MESH]|Cardiopulmonary Bypass[MESH]|Echocardiography[MESH]|Female[MESH]|Follow-Up Studies[MESH]|Heart Valve Prosthesis Implantation/methods/*standards[MESH]|Hospital Mortality/trends[MESH]|Humans[MESH]|Male[MESH]|Middle Aged[MESH]|Mitral Valve Insufficiency/diagnostic imaging/mortality/*surgery[MESH]|Retrospective Studies[MESH]|Survival Rate/trends[MESH]|Treatment Outcome[MESH] |
