Abnormal Origin of the Pulmonary Artery from the Ascending Aorta in the Neonate.

The anomalous origin of one pulmonary artery from the ascending aorta is a rare congenital heart disease, generally diagnosed based on the clinical information and on echocardiographic and computed tomography angiography findings. Here we report two neonates successfully treated with surgery early in life.

Superior vena cava obstruction after the Glenn procedure.

Acute obstruction of superior vena cava anastomosis right after the Glenn procedure may lead to tragic consequences. We describe the case of a one-year-old child with tricuspid atresia and a previous Blalock-Taussig shunt procedure, who presented severe low cardiac output syndrome right after the Glenn procedure and died forty-four hours after the procedure. The autopsy showed obstruction of the superior vena cava anastomosis.
