The clinical studies were performed on 304 patients with heart disease who had been received corrective heart surgery at Kosin Medical Center from July, 1984 to December, 1991. The results were follows : 1) Out of 304 patients, 162 cases (53.3%) were male and 142 cases (46.7%) were female and sex ratio was 1.15 : 1.35 cases (11.5%) had clinical cyanosis and 269 cases (88.5%) had no evidence of cyanosis. 2) As age distribution of patients, under 2 years, 3~5 years, 6~10 years, 11~15 years, 16~18 years consist of 22.0%, 26.0%, 16.1% and 6.9% respectively. 3) As disease distribution, out of 304 patients, ventricular septal defect (57.9% of all) was the most common disease, and then atrial septal defect (13.2%), tetralogy of Fallot (11.2%) patent ductus arteriosus (9.9%) and pulmonic stenosis (5.3%), in their order. 4) As sex distribution of each disease, ventricular septal defect, atrial septal defect and tetralogy of Fallot were more common in male and patent ductus arteriosus and pulmonic stenosis were more common in female. 5) The most frequent cardiac anomaly associated with ventricular septal defect and atrial septal defect was pulmonic stenosis. In the case of subarterial ventricular septal defect, aortic insufficiency was associated in 13.3%. 6) Respiratory problems (11.3%), tricuspid regurgitation (9.5%), arrhythmia (6.2%) and congestive heart failure (5.8%) were the major complications after surgery. 7) Case fatality rate was 4.4%, Mortality rate in ventricular septal defect, tetralogy of Fallot and tricuspid atresia were 1.7%, 20.6% and 100%, respectively. Majority (75.0%) of expired patients were died within 24 hours after surgery and the cause of death was hypoxia due to low cardiac output syndrome.
