The anatomy of the coronaries presents great variability, as confirmed by the anatomists' interest in elucidating the coronary circulation. CT angiography is a method that allows the evaluation of the vascular anatomy and the diagnosis of vascular diseases. The images were obtained with a Somatom Siemens 64 angiograph. The incidence of the origin variants of the coronaries in the studied material was 1.6%. In accordance with the literature, these anomalies were grouped in 2 categories: anomalies of coronary sinus origin and anomalies of ectopic origin. The following varieties were revealed in the first category: left coronary artery originating in the right coronary sinus; left coronary artery arising from a common trunk with the right coronary; circumflex artery originating in the right coronary artery and left coronary artery arising from the posterior part of the aorta. In one case, the ectopic origin of the left coronary artery was the pulmonary artery. About 20% of the coronary artery anomalies cause symptoms such as arrhythmia, syncopes, myocardial infarction or sudden cardiac death. Early identification of an anomalous coronary anatomy is relevant because of the increased incidence of sudden cardiac death. CT angiography plays an increasingly important role in the diagnosis of coronary artery anomalies, as it is a non‐invasive method that provides detailed three‐dimensional anatomical data.
