Left Atrial Myxoma Associated with Malignant Anomalous Course of Right Coronary Artery: A Rare Concurrent Incidence of Two Rare Diseases

Abstract

Cardiac atrial myxoma is a primary cardiac tumor with a prevalence of 0.0017-0.19% at autopsy. Anomalous origin of right coronary artery (ARCA) from opposite sinus of Valsalva is considered the second most common cause of sudden cardiac death among young athletes with an incidence of 0.09%-0.92% and mortality risk of 0-57%. We present a case of symptomatic left atrial myxoma in the presence of ARCA from the opposite sinus of valsalva. The myxoma was excised and the anomalous right coronary artery was re-implanted during the same operative session.
