Abstract

Six cases of atrial septal defect were repaired under direct vision utilizing extracorporeal circulation. Among six cases of atrial septal defects , three cases were male and remainders female. Their ages ranged between ten and thirty-eight years. All six cases were Secundum type atrial septal defects , of which one was complicated by severe pulmonary hypertension, one was combined with partial anomalous pulmonary venous drainage, and the last case was low sinus venosus type defect near the entry of inferior vena cava. Five cases were repaired by direct sutures while the one combined with partial anomalous pulmonary venous drainage needed Ivalon patch. The average entire perfusion time to repair the defect was 32 minutes; the shortest 1~ and the longest 50 minutes. There was no surgical mortality and followup studies of these cases were found to be excellent.
