Two patients with perimembranous extending outlet were repaired because of residual shunt(0.4cm,0.3cm) on the anterosuperior rim of defect. One patient with trivial residual shunt(0.15cm) on the posteroinferior rim of defect was found closed spontaneously six months later. Tricuspid valve was incised in 10 patients of VSD sextending outlet,8 patients vertical to the valve ring,2 patients parallel to the valve ring. Moderate tricuspid valve regurgitation was found in 1 patient, mild in 5 patients, trivial in 4 patients. No one aggravated. One patient complicated with pericardial effusion.
