OBJECTIVE: Early results of reconstructions operations in patients with common mitral valve prolapse by using resection technique and loop technique.
METHODS:A total of 100 patients (65 male,35 female) underwent mitral valve repair with Gore-Tex loops for severe degenerative valve incompetence. 3 of these patients have the Marfan syndrome. The mean age was 52 15, the mean preoperative ejection fraction was 68,2 7,5%, the mean NYHA functional class was 3,57 0,68 and the mean logistic EuroSCORE was 5,12% 2,12. Posterior mitral leaflet prolapse was diagnosed in 18 patients, anterior leaflet prolapse - in 15 patients, both leaflet prolapse - in the remaining 67 patients.
RESULTS: All patients receiwed the loop technique and the ring annuloplasty, with a mean ring size 32,8 2,57 mm. In 25 patients loops were used for the posterior leaflet only, in 37 patients for the anterior leaflet only, and in 38 patients for both leaflets. Quadrangular resection was performed in 35% of cases. Sliding annuloplasty was performed in 17% of patients. The associated procedures included tricuspid valve reconstruction (75 patients - 75%), myocardial revascularization (18 patients - 18%), David-1 procedure (12 patients), atrial fibrillation ablation (7 patients).
CONCLUSIONS: 1. Multicomponent mitral valve reconstruction by using pre-measured gore-tex loops provides excellent hemodynamic effect.2. The resection techniques must additionally used in patients with excess tissue of the posterior mitral valve.
