Long-term results of mitral valve reconstruction for regurgitation of the myxomatous mitral valve

摘要: Abstract The myxomatous, degenerated, prolapsed or "floppy" mitral valve is the most common cause of regurgitation in North America. Mitral reconstruction for was carried out 219 consecutive patients with a myxomatous from 1984 to 1993. Of 139 men and 80 women, 23 84 years age (mean 63 years), 36% were 70 older, 77% New York Heart Association functional class III IV, 29% had coronary artery disease necessitating bypass. operation posterior leaflet resection (161 [73%]). anterior resected 14 patients, both leaflets 15 patients. A variety other techniques used, including commissuroplasty use annuloplasty rings. flexible Duran ring used 111 (51%), Carpentier-Edwards 44 (20%), no 64 (29%). Five operative deaths occurred (2.3%); four five older (5.1%); one 141 (0.7%) younger than age. In late postoperative period follow-up 2 90% symptoms, two endocarditis, seven thromboemboli (transient four, permanent three). Structural degeneration requiring reoperation 12 patients; eight posterior; six ring. incidence structural less 5% 1990 No systolic motion seen echocardiography before discharge. Actuarial analysis at 5 overall survival 86% ± 5%, freedom infectious 97% 2%, thromboembolism 94% 3%. Freedom 83% 4%, it 89% 6%, rigid 88% 67% 12% ( p = 0.03). complicated valve, regardless involvement, feasible offers excellent early results. (J T HORAC C ARDIOVASC S URG 1994;107:143-51)
