Midterm results of edge-to-edge mitral valve repair without annuloplasty

摘要: Abstract Objective Edge-to-edge mitral valve repair is usually performed in association with annuloplasty, rare exceptions. We retrospectively analyzed the results of ringless edge-to-edge repair, particularly view minimally invasive and percutaneous approaches. Methods From November 1993 to December 2001, 81 patients underwent without associated annuloplasty. The cause was degenerative most patients. In 32 annulus severely calcified. Type I lesions were present 6 patients, type II 60 III 15 A double-orifice done 69 paracommissural 12 5 used as a rescue procedure. Results There 3 hospital 4 late deaths, for 4-year survival 85% ± 6.7%. At latest follow-up, 63 New York Heart Association classes or II, 9 IV. Nine required reoperation (89% 3.9% overall freedom from at years). Annular calcification greater rate (77% 22% vs 95% 4.6% reoperation, P = .03). Intraoperative water testing postrepair transesophageal echocardiography predicted failure. Only 1 42 follow-up period when annular calcification, rheumatic disease, procedure not risk factors. Conclusions Our data confirm suboptimal technique annuloplasty added repair. cause, worst outcome. Midterm selected encourage future developments catheter-based procedures.
