Percutaneous device closure of nonrestrictive aortopulmonary window in a 4 months' infant.

Aortopulmonary window is a rare congenital heart disease occurring in 0.2-0.6% of all patients with congenital heart disease. It is usually nonrestrictive and is conventionally treated surgically at an early age to prevent the development of pulmonary vascular obstructive disease. In 10% of the patients, it is restrictive and case reports of its percutaneous closure are mostly limited to these patients. We report percutaneous device closure of nonrestrictive AP window in a 4 months old, 4 kg child. To the best of our knowledge this is the youngest child to have undergone percutaneous device closure of an AP window.
