A rare case of tetralogy of Fallot-pulmonary atresia with absent right pulmonary artery and anomalous origin of left pulmonary artery from ascending aorta.

We report a case of a 5-year-old child with tetralogy of Fallot-pulmonary atresia with anomalous origin of left pulmonary artery from ascending aorta and right lung supplied by collateral arteries. This case highlights the role of preoperative CT angiography in differentiating this entity from a common arterial trunk with discontinuous pulmonary arteries.
