Mitral valve repair in patients with endomyocardial fibrosis.
Between 1987 and 1990, 12 patients were operated on for endomyocardial fibrosis at our institution. Nine were treated by endocardectomy and mitral valve repair and constitute the material of this study. Ages ranged from 9 to 58 years (mean age, 32.5 years). Biventricular involvement was present in 3 cases, and 6 patients had predominantly left ventricular endomyocardial fibrosis. Six patients were in New York Heart Association class III/IV. Six patients had severe mitral insufficiency (3 to 4/4) and 3 patients had moderate mitral insufficiency (2/4). The operation consisted of left ventricular endocardectomy with complete detachment and mobilization of the posterior leaflet of the mitral valve in all cases. An autologous pericardial patch was used to reconstruct posterior leaflet continuity in 4 patients. In 7 patients a prosthetic mitral ring was used. In 3 patients right ventricular endocardectomy and tricuspid valve repair were also performed. All patients survived and none required early reoperation. Follow-up was complete and ranged from 9 to 38 months. No late deaths occurred, and 1 patient required mitral valve replacement for recurrent mitral regurgitation. Doppler echocardiographic studies were performed in 7 patients and revealed no or mild mitral insufficiency. In conclusion, mitral valve repair is safe and offers good early and late results in patients with endomyocardial fibrosis.
