Origem anômala da artéria coronária esquerda do seio de Valsalva direito

This article reports an anatomic specimen specifically prepared to demonstrate a rare anomaly of the origin of the left coronary artery from the right sinus of Valsalva, with an incidence of 0.15% in patients undergoing coronary angiography. This is a subgroup of coronary artery anomalies with the greatest potential for clinical repercussions, especially sudden death in young patients. Based on current knowledge, pathophysiologic mechanisms, diagnosis and treatment options of anatomical variations of the anomalous origin of a coronary artery from the contralateral sinus are discussed.
