Eighteen neonates with surgically treated congenital heart disease have been reviewed. The rate of operative mortality was 56 percent (10 deaths). Only six patients (33%) in this series are postoperatively survived. Nine patients had undergone open heart surgery under hypothermia and three have survived. Three of other 9 patients who had undergone palliative operation have survived. There were five patients with total anomalous venous drainage (TAPVD), of whom two survived after operation. There were four patients with ventricular septal defect and coarctation of the aorta or interruption of the aortic arch. Two of them underwent total correction and were expired. The remaining two patients who underwent coarctectomy or closure of the ventricular septal defect survived after operation. There were three patients with critical pulmonary stenosis or pulmonary atresia with intact ventricular septum. One of these survived after pulmonary valvotomy. Three patients underwent the ligation of the patient ductus arteriosus and two survived. There were one patients with coarctation of the aorta, one with tricuspid atresia and one with ectopia cordis. Causes of deaths were technical failure of operation in four patients, myocardial damage in three and respiratory failure and sepsis in one patient. Myocardial damage was acutemyocardial infarction, which was considered due to inappropriate myocardial protection during surgery.
