Congenital subclavian artery to subclavian vein fistula presenting with congestive heart failure in an infant.

Contrary to acquired arteriovenous fistulas, the congenital malformations are very rare. Here we report a case of congenital arteriovenous fistula forming a communication between the right subclavian artery to subclavian vein. To our knowledge, there is no similar case in which an infant has been successfully operated on for cardiac failure.
