Anomalous Origin of the Circumflex Coronary Artery from the Right Pulmonary Artery: Diagnosis Through Cardiac CT

Origin, Course, and Angulation of Coronary Artery Anomaly - A Case Report

Congenital coronary artery anomalies are a rare diagnosis that can be silent when the patient is asymptomatic. Although these abnormalities may, in most cases, not present clinical alterations, in some cases, they prove to be a cause of myocardial ischemia and sudden death. We report the case of a 20-year-old asymptomatic patient, seen in a routine cardiology consultation, evidenced in an ergometric test ST-segment depression. In this case, follow-up was carried out with coronary angiotomography and scintigraphy to understand the reason for this finding. After the angiotomography has evidenced the diagnosis of anomalous origin and course of the right coronary artery and the trunk of the left coronary artery, in addition to anomalous angulation of the right coronary vessel.
