Physicians holding babies

If your baby has a patent ductus arteriosus (PDA), we offer a minimally invasive treatment option called transcatheter PDA.

About the Patent Ductus Arteriosus

Babies are born with a natural connection between the pulmonary artery and the aorta called the ductus arteriosus. For most babies, the ductus arteriosus closes on its own within a few days or even hours after birth. In some babies, particularly those born prematurely, the connection remains open. This congenital heart defect is called a patent ductus arteriosus (PDA).

A PDA can cause the heart and lungs to work harder because oxygen-rich blood mixes with oxygen-poor blood and returns to the baby’s lungs rather than circulating to the rest of the body. This causes the lungs to handle more blood than normal. A PDA can make breathing more difficult for the baby and cause problems with feeding, breathing, circulation and poor weight gain.

Innovative Approach to Care by an Expert Team

The Heart Center at Orlando Health Arnold Palmer Hospital for Children, in partnership with the neonatal intensive care unit (NICU) at Orlando Health Winnie Palmer Hospital for Women & Babies, offers an innovative approach to babies suffering from a PDA called a transcatheter patent ductus arteriosus closure.

When performed by an experienced team like ours, this procedure is 97% effective.

How a Transcatheter PDA Closure Works

Transcatheter PDA closure is a minimally invasive, non-surgical procedure used to close your baby’s PDA. Our cardiac team will insert a catheter (long, narrow tube) into a vein in their leg, guiding it to the heart and the PDA. The doctor will then insert a closure device through the catheter and permanently place it in the PDA. It will act as a plug to stop the extra blood flow into the lungs. Over time, tissue grows around this device, and there’s no need for a follow-up procedure to remove it.

Transcatheter PDA closure is less invasive than traditional heart surgery, and in most cases, we can further reduce stress on your baby by keeping them on their neonatal ventilator — as opposed to switching them to an anesthesia machine — for the procedure. As a result, a transcatheter PDA closure poses fewer risks, and offers a faster recovery and better outcomes for your baby.
