[Myocardial imaging with thallium -201 in the patients with coronary involvement after Kawasaki disease (author's transl)].

Coronary cine-angiography (CAG) was performed in 290 cases with the history of Kawasaki disease, in whom 57 cases (19.6%) were found to have coronary involvements. In 42 out of these 57 cases, myocardial imaging with thallium-201 (201Tl) was performed, and abnormal findings were seen in 6 cases. Five of these 6 cases showed not only coronary aneurysms, but also coronary obstructive lesions on CAG, while the remaining case showed only coronary aneurysms. The decrease of the uptake of 201Tl by the myocardium appeared to be mainly due to the decrease of regional myocardial blood flow, especially in those cases with obstructive lesions. Myocardial imaging with 201Tl seems to be more sensitive than stress electrocardiography by treadmill to detect myocardial ischemia in the patients with coronary obstructive lesions, although it seems less sensitive than stress electrocardiography to detect coronary arterial stenosis.
