Fig. 1

A 59-year female patient with a history of exertional chest pain and dyspnoea presented with progressive chest pain at night. ECG showed ST elevations. Invasive coronary angiography was attempted to detect coronary artery disease under suspicion of acute myocardial infarction. The procedure was technically unsuccessful because of a large aneurysm of the aortic root that hampered selective catheterization of the right coronary artery (RCA). Therefore, chest CT angiography (CTA) was performed. (a,b) ECG-gated cardiac CTA, (a) volume rendering and (b) MIP image, shows a large ascending aorta aneurysm (An) with displacement of the RCA that resulted in an acute angle at the origin of the RCA (black arrow in a) that caused RCA ostial-stenosis. Patient had atherosclerotic plaques with approximately 50 % stenosis in the left anterior descending and circumflex coronary artery as well (not shown)
