What We Do​​​​

We work to correct a defect in the heart that's often present even before birth. In an unborn baby's heart, there's a small blood vessel called the ductus arteriosus, located between the aorta and the pulmonary artery. This is a normal part of blood flow before birth. After a baby is born and begins to breathe, the ductus arteriosus usually closes on its own, but sometimes it stays open. This is called a Patent Ductus Arteriosus, or a PDA.

Your PDA will be closed during a procedure called a heart catheterization.
