The use of the percutaneous route to close the patent ductus arteriosus (PDA) is becoming more common. Transcatheter occlusion is an effective alternative to surgical intervention and is becoming the treatment of choice for most cases of patent ductus arteriosus (PDA) in children and adults.

Most patients with an isolated patent ductus arteriosus (PDA) can have successful treatment by catheterization after the first few months of life.

After the first birthday, the most common treatment for a patent ductus arteriosus (PDA) is occlusion at cardiac catheterization. In fact, as catheterization techniques advance, the ability to close defects in smaller infants has also been reported with high levels of success. Over the last 4 decades, many techniques and devices have been used for patent ductus arteriosus (PDA) occlusion, although definitive closure rates do not approach those of surgery. Contraindications to catheter-based closure involve the size of the patient.
