Tetralogy of Fallot With Interatrial Communication of the Inferior Sinus Venosus Type: A Rare Association Causing Post-Operative Desaturation

This case report describes a rare association of tetralogy of Fallot with interatrial communication of the inferior sinus venosus type (inferior sinus venosus defect). The patient underwent intracardiac repair for tetralogy of Fallot at 8 months of age. His postoperative course was complicated by desaturation. On reexploration, interatrial communication of the inferior sinus venosus type was revealed which went unnoticed on transthoracic echocardiogram as well as on computerized tomogram.
