Mitral annuloplasty with a flexible linear reducer.
Although the ideal technique is still controversial, mitral valve reconstruction for mitral insufficiency usually includes an annuloplasty. From August 1985 to June 1993, 126 cases of pure, acquired mitral insufficiency were repaired by means of a posterior annuloplasty. Whatever the etiology, all types of mitral insufficiency allowing a mitral reconstruction were included. The annuloplasty, performed with a flexible linear reducer, was associated with valvular (62%) and subvalvular (11%) repairs. An associated surgical procedure was necessary in 62% of the patients. Operative mortality was 2.4%, and follow-up (mean 29 months) was complete for all survivors. Five-year survival was 90%. Five-year complication-free rate for emboli was 91%. Only one patient at 12 months underwent reoperation to treat recurrent mitral insufficiency. Ninety-seven patients were in New York Heart Association Class I or II. Follow-up echocardiographic studies on 75% of eligible patients showed a free rate for significant regurgitation of 99%. Mean valve area was estimated at 2.88 +/- 0.85 cm2. These findings suggest that the flexible linear reducer seems to be a reliable device and a valid alternative for annuloplasty.
