Pseudopulmonary artery sling in a 22q11 deletion newborn with tetralogy of Fallot and isolated left subclavian artery.

We report an interest and mystifying cardiovascular imaging in a 22q11 deletion neonate with rare congenital heart defects, including anomalous origin of the left pulmonary artery arising from the right pulmonary artery and in front of the trachea, called pseudo-pulmonary artery sling, combined with isolated left subclavian artery confirmed by multidetector row computed tomography.
