Background: Anomalous coronary arteries occur in less than 1% of the population and have been implicated in sudden cardiac and exercise-related death. The most common variant involves the left circumflex artery arising from a separate ostium than the left coronary artery. This case demonstrates a rare variation in which all three coronary arteries arise from a shared, single, ostium originating from the right coronary cusp. Case presentation: We report the case of a 63-year-old Caucasian man with a history of myocardial infarction, congestive heart failure, and atrial fibrillation who presented for syncope. Inpatient ischemic workup, including coronary angiography, demonstrated a rare coronary anomaly which included all three coronary arteries arising from a shared, single, ostium originating from the right coronary cusp. Our patient was treated conservatively with an option for coronary bypass if symptomatic. Conclusion: Surgical management is indicated in high-risk patients, but the optimal management for a nonmalignant, shared origin for all three coronary arteries has not been explored in detail.
