Abstract
BackgroundCoronary anomalies are rare congenital abnormalities often found incidentally on conventional coronary angiography (CCA) or coronary CT angiography (CTA). They may result in various clinical outcomes. CCA is invasive and not able to demonstrate all coronary anomalies in detail, especially those with complex courses. Multidetector computed tomography (MDCT) enables visualization of the origin and course of coronary arteries. The objective of this study was to investigate the prevalence of origin and termination coronary artery anomalies and the course of these anomalies in patients in a single center in Korea.MethodsTo diagnose coronary anomalies, the angiographic data of 8,864 consecutive patients undergoing 64- or 320-MDCT from September 2005 to November 2011 were analyzed retrospectively.ResultsAmong the 8,864 patients, 103 (1.16%) had coronary anomalies. Ninety (87.4%) patients had origin and distribution anomalies, and 13 (12.6%) patients had a coronary artery fistula. The most common anomaly (41, 39.8%) was an anomalous origin of the right coronary artery (RCA). Of these, three patients received a coronary artery bypass graft.ConclusionsThe prevalence of coronary anomalies in a single center of Korea was 1.16%. The incidence and patterns of coronary artery anomalies in our patient population were similar to those of previous studies.
Highlights
Coronary anomalies are rare congenital abnormalities often found incidentally on conventional coronary angiography (CCA) or coronary computed tomography (CT) angiography (CTA)
Ninety (87.4%) patients had origin and distribution anomalies, and 13 (12.6%) had a coronary artery fistula (Table 2)
The most common type was a right coronary artery (RCA) originating from the left sinus of Valsalva (LSV) (41 patients, 39.8%) (Figure 1). All these anomalies passed between the aortic root and the pulmonary artery
Summary
Coronary anomalies are rare congenital abnormalities often found incidentally on conventional coronary angiography (CCA) or coronary CT angiography (CTA). The prevalence of coronary artery anomalies is reported to be approximately 0.3% to 2% of the general population [1,2,3,4,5,6,7,8,9,10,11] Most of these anomalies are asymptomatic during life, and the prognosis is good. Some of these anomalies are associated with syncope, ischemic heart disease, and sudden death [12,13,14,15,16,17] These anomalies are detected as incidental findings during coronary angiography or at autopsy. The aim of this study was to evaluate the prevalence of coronary anomalies in consecutive patients who underwent MDCT coronary angiography at Ilsan Paik Hospital, Inje University College of Medicine in Korea
