Transcatheter Patent Ductus Arteriosus Closure
Also known as: PDA closure, closure of ductus arteriosus by cardiac catheterization.
What is transcatheter patent ductus arteriosus closure?
Patent ductus arteriosus (PDA) is a congenital heart defect that causes the ductus arteriosus, a blood vessel that connects the aorta with the arteries going to the lungs, to remain open. This vessel should normally close in the first several hours after birth. Transcatheter patent ductus arteriosus closure is a method of correcting this defect without the need for a surgical procedure and avoiding a scar on the chest/back.
What happens during the procedure?
A catheter (a long, thin flexible tube) is inserted into a blood vessel in the groin area, and advanced to the PDA. A device that acts like a plug is inserted into the catheter and placed within the PDA, blocking the abnormal blood flow.
Is any special preparation needed?
You/your child will need to stop taking liquids and food, as well as certain medications, the night before the procedure. If you/your child are taking blood-thinners you may be asked to stop taking them a few days before the procedure.
What are the risks?
Transcatheter PDA closure is a very safe procedure and complications are rare. Potential complications include impingement on surrounding structures, dislodgment of the device, and soreness/bruising at the groin site where the vessels were entered in order to do the procedure.
