title: Exertional dizziness and syncope caused by anomalous left coronary artery origin from the right sinus of Valsalva.
abstract: Coronary anomalies are generally rare, but has fascinating congenital cardiac disease entities, recognized in less than 1.3% of all coronary angiograms. Left coronary artery arising from right sinus of valsalva RSOV represents an extremely uncommon subtype. Initial presentations include chest pain, myocardial infarction, arrhythmias, sudden death, and rarely exertional syncope. We report a case of exertional dizziness and syncope, diagnosed to have anomalous origin of left main coronary artery from RSOV. Surgical intervention was curative.
