title: Tricuspid valve detachment for transatrial closure of ventricular septal defects.
abstract: Tricuspid leaflet detachment improves visualization and accuracy of closure of ventricular septal defects via the transatrial route. Between July 1998 and March 2001, surgical correction was performed in 296 cases of isolated ventricular septal defect, 215 cases of tetralogy of Fallot, and 16 cases of double-outlet right ventricle. Of these, 132 patients (79 with isolated ventricular septal defect, 49 with tetralogy of Fallot, and 4 with double-outlet right ventricle) underwent transatrial repair with temporary detachment of tricuspid leaflets for ventricular septal defect closure. The septal leaflet was detached in most cases, with anterior or posterior leaflets being detached when indicated. Median duration of intensive care was 3.6 days, and median hospital stay was 7 days. There was no incidence of tricuspid regurgitation attributable to leaflet detachment, as confirmed by postoperative echocardiography. Reoperation was not required for a residual defect or tricuspid regurgitation. The benefits of temporary leaflet detachment for transatrial repair of various difficult defects far outweigh the risk of postoperative tricuspid regurgitation.
