Introduction
Coronary artery aneurysm(CAA)is defined as a local dilatation in the coronary artery which is 1.5 times greater than the adjacent normal segment, with the prevalence of 0.3-5% in patients undergoing coronary angiography[1]. The giant CAA is defined as CAAs over 20mm with an incidence of 0.02% to 0.2% in cardiac surgical population [2]. Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital abnormality of the origin or course of a coronary artery that arises from the aorta with the prevalence of 0.1%-1% in both the adult and pediatric populations[3]. However, the optimal treatment of CAA and AAOCA based on detailed information of coronary arteries[1, 3]. Multimodality imaging, including echocardiography, coronary artery angiography, coronary computed tomographic angiography (CCTA), cardiac magnetic resonance imaging (CMR), has been suggested in diagnosing CAA and AAOCA[4]. We report a rare case of multiple giant CAAs combined with anomalous aortic origin of left coronary artery,presenting the vital role of multimodality imaging in diagnosing and developing optimal individualized treatment strategies.
