ResumoMacroaggregates of albumin labeled with 99mTc and 131I were injected into the coronary arteries in 400 patients undergoing coronary arteriography. The three major coronary artery systems were divided into six groups, based upon coronary arteriography and myocardial perfusion color scintigraphy. Myocardial perfusion could not be predicted uniformly by angiography alone. Myocardial perfusion patterns of each group are presented, together with cases illustrating collateral perfusion, myocardial aneurysms, cardiomyopathy, and venous by-pass grafts. If the size and number of particles injected are carefully controlled, the procedure involves insignificant morbidity and no mortality. Myocardial perfusion scintigraphy with radioactive particles reflects the status of the myocardium beyond diseased coronary arteries.
