Anomalous origin of left coronary artery. RAC-sign. A case report

Abstract

Anomalous coronary origin is a rarely diagnosed condition, the first manifestation of which may be sudden cardiac death. Diagnosis of this pathology, as well as other cardiac and coronary anomalies, is based on imaging diagnostic methods. Transthoracic echocardiography is the most accessible screening method to describe the retroaortic anomalous coronary (RAC) sign. However, due to the low detection rate of this condition and the suboptimal sensitivity of echocardiography, anomalous aortic origin often remains undiagnosed. This article presents the diagnosis of an anomalous origin of the left coronary artery through echocardiography and computed tomography in an elderly patient who had previously been observed for a long time for other cardiovascular diseases. With this case report, we want to emphasize the importance of awareness about congenital coronary artery pathology for the timely routing of patients and providing proper care.
