Evaluation of coronary artery aneurysm and stenosis using open-source myocardial perfusion SPECT and coronary computed tomographic angiography image fusion software.

摘要

A 49-year-old man with a past history of percutaneous coronary intervention presented with chest pain during emotional stress. His chest pain was mild, nonexertional, and spontaneously relieved without intervention. His past medical history was significant for hypertension, diabetes, dyslipidemia, smoking, and morbid obesity. Four years previously, he had undergone coronary angiography revealing obstructive coronary artery disease in the first obtuse marginal and the right posterior descending arteries as well as a coronary aneurysm in the right coronary artery, and undergone intervention with sirolimus-eluting stents in the obtuse marginal and posterior descending arteries. He was taking aspirin, clopidogrel, metoprolol succi-nate, and fenofibrate with intermittent adherence. He did not report any history of Kawasaki disease and had an unlimited exercise tolerance.
