Twelve patients with ventricular septal defect with Down syndrome (Down group) underwent cardiac surgery. As they had pulmonary hypertension (Pp/Ps > or = 0.5), we chose twenty patients who had pulmonary hypertension (Pp/Ps > or = 0.5) with ventricular septal defect without Down syndrome as control group. After cardiac surgery, Pp/Ps in Down group decreased significantly from 0.81 +/- 0.14 to 0.48 +/- 0.25 (p < 0.01). Cardiac index (l/min/m2) between 24 hours after operation was 3.3-3.8 in Down and 4.1-4.8 in control group (NS). Oxygenation index (mmHg) between 24 hours after operation was 211-266 in Down and 230-314 in control group (NS). Eleven out of 12 patients in Down group had good operative result. One patient was complicated with post-operative pulmonary hypertensive crisis. Low output syndrome and death were not encountered in Down group. We were satisfied with operative results and encourage surgical treatment for ventricular septal defect with Down syndrome.
