Patch Repair of Anomalous Origin of Left Anterior Descending Artery From the Right Coronary Artery.

Coronary artery anomalies occur in an estimated 1.3% of the population. We present the case of a 52-year-old man who had a less common anomaly of a left anterior descending artery arising from the right coronary ostium, causing ischemia and chest pain, demonstrated by perfusion scan. The usual options for management of coronary anomalies were not suitable for this anatomy, and therefore we present a case of patch augmentation of the arteries.
