VSD is the most common congenital carciac malformation and the natural history depends not only on the age ofpatients and the size of defect but the subtype of VSD as well, important factor in clinical management or thosepatients. In 110 patients, with surgically repaired VSD in Yonsei Medical Center in 1984, the subtype of VSDs evaluated by surgical observation were correlated with LV angiogram findings to verify the incidence of subtype inKorean and the diagnostic accuracy to predict the subtype by angiogram. 1. 110 patients included 64 boys and 46 girls, the age ranged from 3 months to 14 years(average 4.6 years old) 2. Angiographic findings were interpretedas follows; a. Perimembranous defects were profiled in LAO 60 degrees LV angiogram and located below the aorticvalve. In inlet excavation the shunted blood opacified the recess between septal leaflet of tricuspid valve and interventricular septum in early phase, in infundibular excavation opacified the recess between anterior leafletof TV and anterior free wall of RV and in travecular excavation the shunted blood traversed anterior portion of TVring, opacified trabecular portion of RV cavity. b. Subarterial type were profilled in RAO 30degrees LV angiogram,just below aortic valve as well as pulmonic valve. Total infundibular defects were profilled in RAO 30degrees andLAO 60 degrees LV angiogram subaortic in location in both views. c. In muscular VSD the profilled angle was variedaccording to the subtype but the defects were separated from the aortic valve as muscular septum interposedbetween the aortic valve and the defect. 3. The incedence of subtype of VSDs evaluated by surgical observationwere as follows. Subaterial type 32 cases(29.1%) Total infundibular defect 5 cases( 4.5%) Perimembranous type 73cases(66.3%) Infundibular excavation 32 cases(29.1%) Trabecular excavation 28 cases(25.5%) Inlet excavation 10cases(9.1%) Mixed 3 cases(2.7%) Muscular type 1 cases(0.9%) Total 63.6% of VSD, were the varieties of theinfundibular septum type. 4. The prediction of VSD subtype accoridng to the angiographic findings described above,were compared to the surgical observation. Diagnostic rate was 100% in perimembranous type, 75% in subarterialtype, 0% in total infundibular type, so 88% of cases were in accordance with the surgical findings.

A hypothermic, low flow perfusion, using 5% dextrose in water as the priming fluid in the pump-oxygenator, was carried out to observe oxygen consumption, blood pH changes, and CO2 tension during the bypass period. A low oxygen consumption which was approximately one third of the preperfusion value, was observed during the total by-pass period. This is believed to be due to the effect of low flow rates employed, hypothermia and low CO2 tension observed in these animals. The pH of the arterial blood and the partition of the total CO2 remained within a fairly normal range. There was a marked reduction in CO2 tension during the bypass period. Its harmful effect on the oxyhemoglobin dissociation curve and cerebral circulation was discussed. The hemodilution attendant to the use of 5% dextrose in water as the priming fluid is considered insignificant.

Tetralogy of Fallot is one of the most common cyanotic congenital heart disease. It consists of four features anatomically pulmonic stenosis or atresia, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. One hundred and ninety one cases of Tetralogy of Fallot were confirmed by cardiaccatheterization at Severance Hospital. These were observed on general feature, cardiac catheterization findings and outcome of operation during the period from Jan. 1964 to Dec. 1980. The results of this study may be summerized briefly at follows: 1. Out of the 27365 admitted patients, 1132 cases had congenital heart disease, and 191 cases were Tetralogy of Fallot. This amounted to 16.9% of all those with congenital heart disease. 2. Of the 191 cases, 127 were males and 64 were females. 3. The electrocardiographic findings showed 147 cases of right axis deviation(84.0%), 144 cases of right ventricular hypertrophy(83.1%). Chest P-A revealed that normal cardiothoracic ratio were 137 cases(74.8%), and cardiac apex elevation were 126 cases(68.8%). 4. Pulmonic stenosis were chiefly valvular and infundibular stenosis on cardiac catheterization of 191 cases of TOF(68.6%). 5. The cardiac disease associated with TOF were 80 cases in all; 59 cases with patient formen ovale, 11 cases with atrial secundum defect. 6. There were significant correlation between secondary polycythemia and thrombocytopenia. 7. Complications of TOF were 3 cases of infective endocarditis, 3 cases of cerebral thromboembolism and 1 case of brain abscess. 8. Among 191 cases, only 146 cases received operation, and over all fatality rate were 20.9%. The number of patients with total correction were 89 cases, 42 cases with shunt operation, and 15 cases with total correction after shunt operation. The fatality rate of operation was worst in the group, who received total correction after shunt operation(46.6%). The were 8 cases in group 1, 154 cases in group 2, and 29 cases in group 3 by Nadas classification. The fatality rate in group 1 was higher than any other groups(42.8%). The group with the ratio of main pulmonary artery to aorta size with less than 1/3, showed the highest fatality rate(50%) than other groups.
