Anomalous origin of the right coronary artery from the left sinus of Valsalva and coursing between the aorta and pulmonary artery is a rare congenital abnormality representing less than 3% of the congenital coronary anomalies. Patients can present with myocardial ischemia, arrhythmias, or sudden cardiac death (SCD). This diagnosis should be suspected in young patients without risk factors for coronary artery disease and the diagnosis can be confirmed easily by 64-slice MDCT angiography. Surgery is generally recommended in symptomatic patients whereas conservative management in asymptomatic patients. Incidence of SCD is rare after the age of 35 years and hence conservative treatment may be advised in asymptomatic patients over the age of 35 years.
