Abstract

Background: Anomalous origin of coronary artery (AOCA) has been described by coronary angiography or autopsy. However the actual prevalence of such abnormalities is unknown. Multi-detector computed tomography (MDCT) offers the possibility to visualize AOCA non-invasively. The purpose of this study was to report the prevalence AOCA by MDCT. Methods and results: In 5869 consecutive subjects who underwent coronary MDCT (Aquilion 64, Toshiba Medical Systems Corporation, Otowara, Japan) at one center, the prevalence of AOCA was 89 (1.52%) patients. The most common abnormality (33 cases, 0.56%) was the origin of the coronary artery or branch from the opposite or non-coronary sinus. The right coronary arteries (RCA) arising from the left coronary artery sinus (LCS) was observed in 27 cases (0.46%). Vascular cross-sectional area of such RCA arising from LCS was significantly smaller in 11 patients with angina than in 10 patients without symptoms [3.02 (1.68-7.67) mm2 vs 5.93 (2.54-12.04) mm2 p
