Percutaneous closure of small subpulmonic ventricular septal defect with an ADO I PDA occluder in a child.

Ventricular septal defects (VSDs) comprise the most common congenital heart defect at birth. The chances of spontaneous closure of VSD depend on the size and location of the defect. Subpulmonic location is an unlikely site for the VSD to close spontaneously and known to have complications such as aortic valve prolapse and regurgitation. Percutaneous closure has become the preferred strategy for small-moderate-sized VSDs located in muscular, perimembranous areas. Subpulmonic location poses concerns due to the close proximity to the aortic valve. Herein, we present a case of percutaneous device closure of a subpulmonic VSD using ADO I occluder device.
