Abstract
An anomalous origin of a coronary artery is a rare congenital condition in which a coronary artery arises from the opposite coronary sinus. Most coronary artery anomalies are an incidental finding without clinical significance, although some cases may be potentially life threatening, depending on the origin, course and termination of the anomalous vessel. Anatomical features of risk are an aortic intramural course or inter-arterial course.
Highlights
An anomalous origin of a coronary artery is a rare congenital condition that affects 1% of the population [1,2]
Some authors have described the anomalous origin of the right coronary artery (RCA) from the left coronary sinus (66% cases) as the most frequent coronary anomaly [1,3]
We present 4 cases of an anomalous origin of the coronary artery with radiological confirmation by computed tomography angiography (CTA)
Summary
We present 4 cases of an anomalous origin of the coronary arteries with radiological confirmation by cardiac computed tomography angiography (CCTA) and clinical history of chest pain. Two patients were incidentally diagnosed by invasive coronary angiography, while two of them underwent a CCTA exam directly. Ischemia detection tests such as treadmill test or myocardial perfusion imaging with single photon emission computed tomography (SPECT) were performed in all of them to rule out ischemia
