Mitral valve repair for isolated prolapse of the anterior leaflet: an 11-year follow-up.

摘要: Objective: Mitral valve insufficiency (MVI) because of involvement the anterior mitral leaflet may pose additional risks for late outcome after repair, more complex techniques. We retrospectively reviewed our experience in patients operated on isolated prolapse approached by various Methods: Between 1986 and 1997, 616 underwent repair at Institution. Isolated pathology was cause MVI 84 (13.6%). Age ranged from 23 to 74 years (mean 50 ∠ 14). Etiology predominantly degenerative (57 patients, 67.8%), mechanism regurgitation mainly due a chordal rupture (58 69%). Annular dilatation present 75 (89.5%). A variety surgical techniques were applied including shortening (five 5.9%), transposition (three 3.5%), artificial chordae (11 13%). Since 1992, however, majority procedures performed using ‘edge edge’ technique (52 51.9%). treated means prosthetic ring (46 61.3%) whereas 18 (24%) posterior annuloplasty gluteraldehyde-treated native pericardium. Results: Follow-up 3 122 months 46 24 months). There three hospital deaths (3.5%) five (5.9%) Kaplan-Meier estimated survival 87.6% 8 years. Three early reoperation within 30 days (3.5%), six (7.1%), cumulative freedom 85.4% Seventy-four percent survivors (50 patients) are still New York Heart Association Class I, 92% (62 have no or trivial (1+) residual echocardiographic follow-up. Conclusion: In spite greater complexity, conservative surgery correct pertains high success rate long term. Recent technical modifications (‘edge-to-edge’ technique) allow expeditious reproducible with expected favorable influence applicability. © 1999 Elsevier Science B.V. All rights reserved.
