A Particular Infantile Scimitar Syndrome Variant with Anomalous Systemic Arterial Supply-Inferior Vena Cava Fistula

Abstract Scimitar syndrome is a rare congenital cardiovascular malformation that includes a partially anomalous drainage of the pulmonary veins in the inferior vena cava, right pulmonary hypoplasia, and systemic-pulmonary collaterals originating from various segments of the aorta. We present a case of Scimitar syndrome with associated intracardiac lesions and a large arterial conduct supplying the right lung, originating from the abdominal aorta and draining in the inferior vena cava.
