Percutaneous closure of nonrestrictive aortopulmonary window in three infants

Aortopulmonary (AP) window, a communication between ascending aorta and pulmonary artery, is usually nonrestrictive and causes severe pulmonary vascular obstructive disease early in life. Only in 10% of the cases it is restrictive. There are sporadic case reports [1-8] of device closure of AP window which are mostly confined to these restrictive AP windows, that too in adults or relatively older children. Till date there is a single case report of device closure of nonrestirctive AP window in an infant [8]. We report our single experience of device closure of large, nonrestrictive AP windows in 3 infants. Percutaneous closure of AP window in each of the three patients was done by a different type of device i.e. duct occluder, muscular VSD occluder and perimembranous VSD occluder.
