Aberrant origin of the left main coronary artery arising from the right coronary artery associated with coronary artery disease: a case report.

Recognition of these anomalies is fundamental in patients undergoing diagnostic or interventional coronary angiography. Most patients presenting with coronary anomalies are asymptomatic, but the risk of myocardial ischemia and sudden death requires the treatment of those patients.
