ASD & PDA Device Closure

Atrial Septal Defect is an abnormality of the upper chambers of the heart (atria) where the wall between the right and left atria does not close completely. This defect is present at birth (congenital).

Patent ductus arteriosus (PDA) is a condition where the ductus arteriosus, a blood vessel that allows blood to bypass the baby's lungs before birth, fails to normally close after birth. The word "patent" means open.

Device closure of atrial septal defects and patent ductus ateriosus is an effective and fairly safe alternative to surgery in infants.

The procedure involves essentially a detailed study of the size and shape of the PDA by angiography, then insertion of the appropriate occlusive device to the PDA site by special catheter under x-ray guidence through the catheter from the vessel of the groin. The result can be immediately checked by echocardiograhphy and angiography
