Abstract

Coronary artery aneurysm (CAA) is a rare cause of myocardial infarction. However, only a few studies have investigated this aspect. An 84-year-old woman with a history of hypertension presented with nausea. showed ST elevation in the inferior leads, and coronary angiography revealed two giant CAAs in the right coronary artery. Percutaneous coronary intervention was difficult because of risk of CAA rupture. Thus, these aneurysms were further evaluated using multimodality cardiac imaging to determine the treatment. MRI using late gadolinium enhancement revealed structural features of the aneurysms and the viability of the myocardium. Only antithrombotic medication was administered on the basis of the results of the multimodality cardiac imaging. Here, we report a rare case of a patient diagnosed with ST elevation myocardial infarction caused by thrombosis in giant CAAs using multimodality cardiac imaging, particularly MRI.
