Usefulness of 64-Slice Coronary Computed Tomographic Angiography in the Planning of Percutaneous Coronary Intervention

Abstract

) with a 2-year history of adult-onset diabetes mellitus pre-sented with dyspnea on exertion and occasional chest discomfort. An electrocardiogram suggested previous inferior wall myocardial infarction of undetermined age. A myocardial perfusion stress test, performed at an outside institution, demonstrated inferior wall myocardial ischemia. The patient was initially unwill-ing to undergo invasive coronary angiography but was amenable to noninvasive, coronary computed tomo-graphic angiography (CCTA). A 64-slice gated CCTA demonstrated only mild narrowing of the left system
