To evaluate the pulmonary extravascular space in patients with congenital heart disease, lung uptake of thallium-201 (T1-201) was quantitatively studied. A total of 50 T1-201 imagings were performed in 33 patients with total anomalous pulmonary venous connection (TAPVC); 4 preoperatively, 22 postoperatively in the early stage (within 6 months), and 24 in the late stage (7 months or later). The images consisted of 17 supracardiac TAPVC (type-I), 13 paracardiac (type-II) and 3 infracardiac (type-III). In patients with tetralogy of Fallot (T/F), T1-201 imaging was performed 15 times preoperatively, 12 in the early stage and 15 in the late stage, postoperatively. Furthermore, 29 patients with ventricular septal defect (VSD) or patent ductus arteriosus (PDA) were also studied preoperatively, and 21 in the late postoperative stage. Twenty-five patients with arrhythmias or a history of Kawasaki disease without perfusion defects were studied on T1-201 myocardial imaging. Lung uptake of T1-201 was analyzed with a computer using the anterior image of the chest, and the average count ratio of the right lung (P) to the left ventricular wall (LV) was calculated. P/LV values were compared between the patients before and after surgery, and differences in anatomical types in TAPVC were also evaluated. In TAPVC, P/LV values decreased gradually in the postoperative state, but were significantly higher than those of controls even in the late stage. In the late postoperative stage, type-I TAPVC had significantly higher P/LV values than those of type-II.(ABSTRACT TRUNCATED AT 250 WORDS)
