Familial Anomalous Origin of Right Coronary Artery from the Left Coronary Sinus

Abstract

Anomalous origin of a coronary artery from the opposite sinus of Valsalva is a rare congenital anomaly. The prevalence of familial clustering of coronary artery anomalies is unknown. Here we describe the case of a father and son, both of whom presented with major adverse cardiac events due to Anomalous origin of a coronary artery from the opposite sinus of Valsalva and both had right coronary artery arising from the left coronary cusp with an interarterial course.
