Abstract

BACKGROUND/AIM: In this study, the aim is to investigate the prevalence of various coronary artery anomalies (CAAs), evaluated by 256-detector row coronary computed tomography (CCT), within the Turkish population.

MATERIALS AND METHODS

We included 2973 patients who had received CCT. The high take-off right coronary artery (RCA) and left coronary artery (LCA), the RCA arising from the left sinus (LS), the LCA arising from the right sinus (RS), the circumflex artery (CX) arising from the RS, the single coronary ostium originating from the RS, the CX arising from the RCA, and the RCA arising from the pulmonary artery were evaluated.

RESULTS

Seventy-nine patients (2.65%) were diagnosed with CAAs. The frequency of high take-off of the RCA, LCA, and both was 0.1%, 0.67%, and 0.06%, respectively. Frequency of separate ostium of the left anterior descending artery and CX was 0.67%. The frequency of RCA originating from the LS, CX originating from the RS, LCA originating from the RS, LCA and RCA originating from the pulmonary artery, and CX originating from the RCA was 0.50%, 0.10%, 0.23%, 0.03%, and 0.20%, respectively.

CONCLUSION

In this study, CCT was demonstrated to be a high-quality imaging modality for the detection of CAAs.

摘要

背景/目的：在这项研究中，旨在通过 256 层冠状动脉计算机断层扫描（CCT）评估土耳其人群中各种冠状动脉异常（CAA）的患病率。

材料和方法

我们纳入了 2973 例接受 CCT 的患者。评估了高位起自右冠状动脉（RCA）和左冠状动脉（LCA）、RCA 起自左窦（LS）、LCA 起自右窦（RS）、回旋支（CX）起自 RS、单支冠状动脉起自 RS、CX 起自 RCA 和 RCA 起自肺动脉的情况。

结果

79 例（2.65%）患者被诊断为 CAA。高位起自 RCA、LCA 和两者的频率分别为 0.1%、0.67%和 0.06%。左前降支和 CX 单独开口的频率为 0.67%。RCA 起源于 LS、CX 起源于 RS、LCA 起源于 RS、LCA 和 RCA 起源于肺动脉以及 CX 起源于 RCA 的频率分别为 0.50%、0.10%、0.23%、0.03%和 0.20%。
