TOTAL CIRCULAR ANNULOPLASTY WITH ABSORBABLE SUTURE FOR THE REPAIR OF LEFT ATRIOVENTRICULAR VALVE REGURGITATION IN ATRIOVENTRICULAR SEPTAL-DEFECT

To obtain a better control of left atrioventricular valve regurgitation, we applied total circular annuloplasty with the use of absorbable sutures to 14 children with atrioventricular septal defect (six complete forms and eight incomplete forms). In the intraoperative period, a good coaptation of the leaflets was achieved and the regurgitation was minimized or disappeared. Follow-up studies with echocardiography for 13 survivors showed a gradual increase of annular size during the postoperative period. Ten patients of the survivor group (77%) maintained good valvular competency in a long-term period. Total circular annuloplasty is a simple and effective procedure to reduce the regurgitation and prevent the annular dilatation during the immediate postoperative period.
