Whole coronary circulation originating from single ostia – Rare case report

The prevalence of coronary artery anomalies is approximately 1% in individuals undergoing angiography. Most of the anomalies are benign, but some can lead to myocardial infarction, cardiomyopathy, and sudden cardiac death. It is very rare to have an entire coronary circulation that arises from the right coronary cusp. We present the case of a 55-year-old female who presented with the complaints of chest pain on exertion with positive stress test. An invasive angiogram revealed all the three coronary arteries originating from the right coronary cusp.
