Acute myocardial infarction after simultaneous thrombosis in normal right and left coronary arteries.

ABSTRACT

A 32-year-old male patient with clinical and electrocardiographic evidence of acute myocardial infarction underwent coronary angiographic study. We observed nonocclusive thrombosis simultaneously in right and left anterior descending coronary arteries, without confirmation of spasm or obstructive artery disease in other coronary branches. Documentation of coronary thrombosis in more than one artery is rare, and its pathophysiology is still unknown. With the advent of thrombolytic therapy and immediate coronary angiographic studies in patients with evolving myocardial infarction, it has been possible to confirm the presence of thrombus and the type of coronary disease. In this case, we observed total lysis of both thrombi and the final aspect of "normal" angiographically reperfused coronary arteries.
