Clues to echocardiographic diagnosis of isolation of right subclavian artery in a patient with DiGeorge syndrome and its transcatheter management with its associated anomalies.

Isolated subclavian artery is a rare anomaly. A second steal due to a patent arterial duct further reduces arm perfusion. Surgical anastomosis of the isolated vessel to aorta normalises arm perfusion. Simple echocardiographic clues aid in the diagnosis. An associated moderate sized ventricular septal defect was non-surgically closed along with catheter closure of the duct resulting in improved arm perfusion.
