Overview
Before birth, a blood vessel called the ductus arteriosus connects the aorta and the pulmonary artery. It normally closes shortly after birth. When it stays open (patent), extra blood flows to the lungs and strains the heart.
A PDA can be closed by a device or coil delivered through a catheter, usually in under an hour.
Who may need it
- Infants, children and adults with a significant PDA
- PDA causing heart enlargement or recurrent chest infections
What to expect
- Performed through the leg vessels.
- The device is positioned within the duct and released once the seal is confirmed.
Recovery & aftercare
- Most patients go home the next day and return to normal activity within a few days.
