Coronary 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.
To 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.
Among 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.
The 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.
冠状动脉异常是罕见的先天性异常，通常在常规冠状动脉造影（CCA）或冠状动脉 CT 血管造影（CTA）中偶然发现。它们可能导致各种临床后果。CCA 是侵入性的，无法详细显示所有冠状动脉异常，尤其是那些具有复杂行程的异常。多排螺旋 CT（MDCT）能够显示冠状动脉的起源和行程。本研究的目的是在韩国的一家单中心研究中调查起源和终止冠状动脉异常的发生率以及这些异常的行程。
为了诊断冠状动脉异常，回顾性分析了 2005 年 9 月至 2011 年 11 月期间连续 8864 例接受 64 或 320-MDCT 的患者的血管造影数据。
在 8864 例患者中，有 103 例（1.16%）存在冠状动脉异常。90 例（87.4%）患者存在起源和分布异常，13 例（12.6%）患者存在冠状动脉瘘。最常见的异常（41 例，39.8%）是右冠状动脉（RCA）的异常起源。其中，3 例患者接受了冠状动脉旁路移植术。
韩国单中心的冠状动脉异常发生率为 1.16%。我们患者人群中冠状动脉异常的发生率和模式与以往的研究相似。
