Abstract： Objective To investigate the outcome of continuous shallow stitching repairing perimembranous ventricular septal defect(pVSD). Methods From January 2002 to October 2004,50 patients less than 10kg of body weight with simple pVSD were chosen in our hospital. VSD was repaired by continuous shallow stitching with autograft pericardium. Results The aortic clamping time was 32±21min（14-52min）, cardiopulmonary bypass time 56±35min（29-69min）.No Ⅲ° atrioventricular conduction block happened, 9 patients developed right bundle branch block, and 2 patients showed junctional rhythm. 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.One patient was reoperated because of bleeding. Conclusion Continuous shallow stitching repairing pVSD is effective.
