Unroofed coronary sinus is a rare congenital cardiac abnormality characterized by the partial or complete absence of the roof of the coronary sinus. Unroofed coronary sinus causes a shunt between the inferior left atrium and coronary sinus, which can lead to pulmonary hypertension and heart failure. Unroofed coronary sinus is typically associated with other congenital defects, most commonly a persistent left superior vena cava. We present the cardiac magnetic resonance imaging findings of a 6-year-old child with a rare unroofed coronary sinus requiring surgical closure.
