OBJECTIVE: We assessed the early- and long - term outcomes for the coaptation surface in patients after correction mitral valve prolapse, by using pre-measured gore-tex loops.
METHODS: 90 patients (60 male, 30 female) underwent mitral valve repair with Gore-Tex loops for severe degenerative valve incompetence. The mean age was from 13 to 76 years old, the mean preoperative ejection fraction was 64 ± 7%, the mean NYHA functional class was 2,7 ± 0,5 and the mean logistic EuroSCORE was 3,02 ± 2,85. Posterior mitral leaflet prolapse was diagnosed in 20 patients, anterior leaflet prolapse - in 15 patients, both leaflet prolapse - in the remaining 55 patients.
RESULTS: No patient died early after the operation. Thirty-day survival was 100% and in echocardiography revealed blindness or mild mitral regurgitation in 100% of patients. The average level of mitral regurgitation decreased from 3.17 ± 0.4 at the beginning to 0.66 ± 0.31 before discharge. Serious recurrent regurgitation was not 72 months in this series, and no systolic forward motion of the mitral valve was observed. The average length of co-adaptation among all patients was 11.06 ± 2.07 mm (10,89 ± 2,31 in long - term outcomes), the average depth of co-adaptation was 4.75 ± 2.1 mm (4,82 ± 2,17 in long - term outcomes). All patients received a loop technique and annular annuloplasty with ring. Quadrilateral resection was performed in 23.53% of cases. Associated procedures included the reconstruction of the tricuspid valve (65 patients - 72.22%), myocardial revascularization (16 patients - 17.78%), David-1 procedure (1 patients), ablation of atrial fibrillation (3 patients). The non-reactive actuarial survival for 72 months in this series was 98.89% ± 0.53%. CONCLUSIONS: Correction mitral valve prolapse by using pre-measured gore-tex loops allow create the best surface of coaptation and have a stable resalts in long - term outcomes
