The prevalence of coronary artery anomalies is approximately 0.6% 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 a case of a 57-year-old male who presented with complaints of chest pain and dyspnea on exertion. An invasive angiogram revealed all the three coronary arteries originating from the right coronary cusp. It is crucial to define coronary anatomy as anomalies dictate which cardiac intervention should be attempted in cases of ischemia.
