Obstructive Cor Triatriatum Sinister with Complete Balanced Atrioventricular Septal Defect and Raghib Complex

A 7-month-old infant presented with recurrent respiratory tract infections associated with intermittent episodes of cyanosis and was diagnosed with obstructive cor triatriatum sinister, complete atrioventricular septal defect (AVSD), and Raghib complex. Surgical repair of cor triatriatum is performed, AVSD is repaired with the double patch technique, and a homologous pericardial patch is used to baffle the unroofed coronary sinus and persistent left superior vena cava into the right atrium. We report this complex congenital cardiac condition due to its rare association with multiple congenital cardiac anomalies.
