Anomalous origin of coronary arteries is a relatively rare entity, which may show different clinical forms and develop an adverse outcome. Multislice coronary angiotomography has gained importance in daily clinical practice, representing an important patient assessment method with great potential in the anatomical evaluation of these arteries.
This study aimed to describe angiotomographic findings and evolution of patients with anomalous origin of coronary arteries.
From January 2008 to March 2011 404 patients were evaluated consecutively, who had been referred for coronary angiotomography for several reasons, with a mean follow-up of 21 months.
Nine patients (2.2%) had anomalous origin of coronary arteries, of which four had an anomalous origin of the Circumflex (Cx) artery in the Right Coronary Artery (RCA), two had anomalous origin of the RCA (one originating from the Cx and one in the left coronary sinus), a patient with single coronary trunk (anterior descending and Cx out of the left coronary sinus), one had anomalous left main coronary artery trajectory between the aorta and pulmonary artery and one patient with left coronary trunk originating from the right coronary sinus. Of the evaluated patients, one received an implantable cardiodefibrillator; one died due to sudden death during hospitalization; and the others showed no complications.
The multislice coronary angiotomography represents minimally invasive assessment method that allows detecting the origin, course and termination of anomalous coronary arteries with excellent accuracy, allowing the correct diagnosis and aiding therapeutic planning.
冠状动脉异常起源是一种相对罕见的情况，可能表现出不同的临床形式，并产生不良后果。多层冠状动脉血管造影术在日常临床实践中具有重要意义，是一种重要的患者评估方法，在这些动脉的解剖评估方面具有巨大的潜力。
本研究旨在描述冠状动脉异常起源患者的血管造影表现和演变。
2008 年 1 月至 2011 年 3 月连续评估了 404 例患者，这些患者因多种原因接受了冠状动脉血管造影检查，平均随访 21 个月。
9 例（2.2%）患者存在冠状动脉异常起源，其中 4 例为回旋支（Cx）动脉起源于右冠状动脉（RCA），2 例为 RCA 起源异常（1 例起源于 Cx，1 例起源于左冠状动脉窦），1 例患者为单支冠状动脉干（前降支和 Cx 发自左冠状动脉窦），1 例患者为左主干冠状动脉在主动脉和肺动脉之间异常走行，1 例患者为左冠状动脉干发自右冠状动脉窦。在评估的患者中，1 例患者接受了植入式心脏除颤器；1 例患者因住院期间猝死死亡；其余患者均无并发症。
多层冠状动脉血管造影术是一种微创评估方法，可准确检测异常冠状动脉的起源、走行和终止，有助于正确诊断和辅助治疗计划。
