Although the prevalence of coronary artery anomalies (CAA) is due to accidental and rare discoveries, it varies between different countries or geographies. CAA are rare congenital disorders having various clinical definitions. Its prevalence varies in angiographic and autopsy series in adult populations and is approximately 1% in average. While the incidence ranges from 0.2% to 5.64% in coronary angiographic (CAG) studies, it is around 0.3% in autopsy series. We aimed to estimate the frequency of CAA in our patient population.
The coronary angiographic data of 4099 consecutive adult patients, who underwent CAG between January 2019 and December 2020, were analyzed and retrospectively studied.
The mean age of the total patients who underwent CAG was 61.59 ± 13.67 years (range, 18-98 years). CAA were found in 76 patients (1.85% incidence), origin and course anomaly in 62 patients (81.6%), and coronary artery termination anomaly in 14 patients (18.4%). Separate exits of the left anterior descending (LAD) and left circumflex (LCX) coronary artery from the left sinus of Valsalva (LSV) were the most common anomalies (36.84%). Coronary artery fistulas were seen in 14 (18.42%) patients. Abnormal origin of left circumflex artery (LCX) from the right coronary artery (RCA) or right sinus valsalva (RSV) was seen in 13 (17.11%) patients. Outflow anomalies from the contralateral coronary sinus were detected in 10 (13.16%) patients.
The incidence and pattern of CAA in our patient population showed similarity with previous studies. Physicians should be aware of CAA that may be associated with potentially serious cardiac incidents, because recognition of these CAA is important for the decision of treatment procedures.
尽管冠状动脉异常（CAA）的患病率是由于偶然和罕见的发现，但在不同国家或地区有所不同。CAA 是罕见的先天性疾病，具有各种临床定义。其在成人人群中的血管造影和尸检系列中的患病率有所不同，平均约为 1%。虽然在冠状动脉造影（CAG）研究中的发生率在 0.2%至 5.64%之间，但在尸检系列中约为 0.3%。我们旨在估计 CAA 在我们患者人群中的频率。
对 2019 年 1 月至 2020 年 12 月期间接受 CAG 的 4099 例连续成年患者的冠状动脉造影数据进行了分析和回顾性研究。
接受 CAG 的所有患者的平均年龄为 61.59 ± 13.67 岁（范围为 18-98 岁）。在 76 例患者（发生率 1.85%）中发现了 CAA，起源和行程异常 62 例（81.6%），冠状动脉终止异常 14 例（18.4%）。左前降支（LAD）和左旋支（LCX）冠状动脉从左窦（LSV）的单独出口是最常见的异常（36.84%）。14 例（18.42%）患者存在冠状动脉瘘。左旋支（LCX）异常起源于右冠状动脉（RCA）或右窦（RSV）见于 13 例（17.11%）患者。在 10 例（13.16%）患者中发现来自对侧冠状窦的流出异常。
我们患者人群中 CAA 的发生率和模式与以前的研究相似。医生应注意可能与潜在严重心脏事件相关的 CAA，因为识别这些 CAA 对于治疗程序的决策很重要。
