title: Posterior annuloplasty in the surgical treatment of mitral insufficiency.
abstract: One hundred and twenty-nine patients underwent posterior mitral annuloplasty with a Gore-Tex tube for mitral regurgitation between January 1982 and June 1991. The hospital mortality was 1.5% (CL = 0.5%-2.5%). The overall survival of hospital survivors was 96.5% +/- 2.7% at five and 86.2% +/- 7.6% at nine years, freedom from cardiac death was 99.1% +/- 0.9% and 95.2% +/- 3.9%, respectively. The actuarial freedom from embolism was 96.1% +/- 2.3% at five and 88.5% +/- 5.5% at nine years. The freedom from endocarditis (one patient) was 100% and 92.6 +/- 7.1%, respectively. Reoperation was necessary in six cases between one and 72 months after the operation (mean 38.5 +/- 30.5 months). The etiology of the valvular insufficiency was rheumatic in all reoperated cases. The freedom from reoperation was 94.1% +/- 3.2% at five and 87.2% +/- 5.6% at nine years. There was no mortality at reoperation. Of the 117 patients alive at the end of follow up and not requiring reintervention, 113 (96.6%) showed good functional improvement and were in NYHA functional class I or II. We conclude that both the immediate and long-term results of reconstructive surgery using the technique of inserting a half-ring on the posterior mitral annulus compare favorably with those obtained using other annuloplasty methods.
