Coronary Artery Anomalies: A Short Case Series and Current Review

Coronary artery anomalies (CAAs) are rare congenital cardiovascular defects that can present in various ways depending on the origin, course, and termination of the abnormal coronary artery fistula. It is sometimes detected incidentally during procedures such as coronary angiography or autopsies. While adults with this condition are often asymptomatic, some may experience angina, congestive heart failure, myocardial infarction, cardiomyopathy, ventricular aneurysms, or sudden cardiac death (SCD). In fact, it is the second leading cause of SCD among young athletes and requires more studies to handle such patients efficiently. To illustrate the many possible manifestations of this unusual diagnosis, we present a series of five cases. We have also reviewed the different varieties of this rare congenital anomaly and discussed the latest diagnostic tests and treatment plans.
