Abstract

|
|
Pulmonary perfusion scan with radioactive 113´In-iron hydroxide particle was performed in the 25 cases of heart disease which had been diagnosed by cardiac catheterization prior to surgery from July, 1972 to July, 1973 at the Department o f Radiology and Nuclear Medicine, Yonsei Medical College.
It consists of 7 mitral stenosis, 2 mitral insufficiency, 1 aortic insufficiency, 3 atrial septal defect, 5 ventricular septa] defect, 2 patent ductus arteriosus, 1 transposition of great vessel and 4 Tetralogy of Fallot.
Findings of pulmonary perfusion ´can in relation to hemodynamic data of cardiac catheterization were examined.
1) Out of 10 cases of acquired valvular heart disease, In 6 cases of mitral stenosis and 1 case of aortic insufficiency, radioactivity was increased at both upper lung. This finding is noted when pulmonary wedge or venous pressure was elevated above 22 mmHg and arterial systolic pressure above 33 mmHg.
2) Out of 15 cases of congenital heart disease. In almost all cases of atrial septal defect and ventricular septal defect except 2 cases, radioactivity was even at both entire lung. In 2 cases of patent ductus arteriosus, radioactivity was decreased especially at the left lung. It is observed that in acyanotic congenital heart disease, radioactivity of lung is not related with pulmonary arterial pressure. In 3 cases of Tetralogy of Fallot, radioactivity was even at both entire lung and in 2 of them, extrapulmonary radioactivity of liver or kidney which depends on size of defect and volume of right to left shunt reversible, was noted.
