Coronary artery anomalies: Rare coronary artery anomalies detected on coronary computed tomography angiography

Coronary artery anomalies are rare congenital cardiovascular defects that can present in various ways depending on the origin, course, and termination of the abnormal coronary artery. It is sometimes detected incidentally during procedures such as coronary angiography or autopsies. Most of the time, they are often asymptomatic, but some may experience angina with congestive heart failure, myocardial infarction, cardiomyopathy, ventricular aneurysms, or sudden cardiac death. In this discussion, we provide a concise overview of three specific cases: One involving a common origin of the left coronary artery and right coronary artery (RCA) from the right coronary sinus, another congenital absence of RCA, and a third case involving a high origin of RCA which were diagnosed by coronary computed tomography angiography.
