Abstract:
The total 223 cases of tetralogy of Fallot is analysed angiographically, in which selective biplanecinecardioangiography with axial projection has been done at the Departement of Radiology, Seoul National University Hopital, in recent 2 year and 4 months, with specific refrence to the location of pulmonic stenosis,and associated cardiac anomalies. The summary of the analysis is as follow; 1. Left ventriculogram (long axialoblique view) was necessary to detect the ventricular septal defects including anterior marginal VSD, and washelpful to identify the coronary artery anatomy and presence of PDA and evaluate the size of left ventricle. 2.Right ventriculogram(elongated RAO view) was the best projection for the demonstration of pulmonic infundibulumand was essential to differenciate and localize the ventricular septal defects. 3.In the right ventriculogram(4chamber view), well demonstrated the right ventricular outflow tract, pulmonary valve, and pulmonaryarteries(main, right, left and peripheral), and also perimitted the detection of ASD in levophase. 4. The positionof ventricular septal defects was perimembranous in 199 cases(89.2%), subarterial in 15 cases(6.8%) andinfundibular (intracristal) in 9 cases(4%). Multiple ventricular septal defects (perimembranous& marginal ) werefound in 11 cases(4.5%). 5. In 35 cases(15.5%), pulmonary stenosis is found only in pulmonary infundibulum. Thecombination of its components was most commonly anterior wall and conus septum hypertrophy in 24 cases(68.6%) 6.Combined pulmonary stenosis was identified in 188 cases(84.3%). The most common combination was infundibular andpulmonary valvular stenosis in 56 cases(29.8%) 7. Associated cardiac anomalies were right aortic arch in 53 cases(23.8%), persistent left SVC in 17 cases (7.7%), ASD in 13 cases (5.9%), PDA in 9 cases(4.1%), aberrant subclavianartery in 5 cases(2.2%), IVC interruption with azygos continuation in 2 cases, single coronary artery in 2 cases,and anterior descending artery from right coronary artery in 1 case, etc. 8. Selective biplanecinecardioangiography with axial projection is essential to evaluate the size of left ventricle and to localizethe ventricular septal defects and pulmonary stenosis, and to detect associated cardiac anomalies in T.O.F. Sometimes aortography is necessary when anomaly of coronary arteries is suspected.
