Radiological evaluation of sinus valsalva rupture

We obtained the following results by reviewing the radiographic findings of 15 cases of Sinus Valsalva rupturewho were diagnosed surgically at Seoul National University Hospital since 1979. 1. Among distribution was from 15years to 40 yeass with the mean age of 24 years. Among the 15 cases, 9 cases were male and 7 were female. 2.Ruptured sinus is right coronary sinus projecting to right ventricle in all 15 cases. Combined diseases areventricular septal defect in 12 cases, Aortic Valvular heart disease in 4 cases, and narrowing of rightventricular outflow tract in 2 cases, and aneurysmal dilatation of right pulmonary artery in 1 case. 3. Chestx-ray findings were that of left to right shunt, i.e, cardiomegaly, increased pulmonary vascularity but werenormal in 3 cases. 4. Aortography showed sequential leakage of dye form right coronary sinus to right ventricleand finally to pulmonary artery in 9 cases, and in 9 cases of them the leakage is directly to right ventricularoutflow tract without filling of sinus portin of the ventricle, i.e., type I. 5. The leakage was well shown inleft ventricular diastolic phase and not shown in systolic phase. 6. Ventricular septal defects were not detecteddefinitely in spite of taking left ventriculography. 7. Cineangiography is essential for detecting accurate site,degree and direction of sinus valsalva rupture and other associated cardiac abnormality.
