Abstract

Coronary artery anomalies can be life-threatening, with a prevalence of approximately 1%. An ectopic origin of the right coronary artery (RCA) from the left sinus of Valsalva accounts for less than 1% of all coronary artery anomalies. Although conventional angiography plays a standard role in diagnosis, recent advances in computed tomography (CT) are more accurate for three-dimensional structures. We report a CT-confirmed symptomatic case of an ectopic origin of the RCA from the left sinus of Valsalva. [Tzu Chi Med J 2008;20(1):67–69]
