Pulmonary Artery Reconstruction (PAR) Program

The heart and lungs work together as a team to deliver oxygen-rich blood to the brain and body to keep us healthy. When the pulmonary arteries and blood vessels in the lungs are damaged, narrowed, or missing, you or your child could benefit from pulmonary artery reconstruction—a surgical procedure that rebuilds arteries and vessels in the lungs to achieve near-normal heart-lung function for improved health and wellness.

Stanford Medicine Children’s Health is the No. 1 place in the world for pulmonary artery reconstruction.

Our Pulmonary Artery Reconstruction (PAR) Program was built upon a heart-lung surgery called unifocalization, pioneered by Frank Hanley, MD, the Executive Director of the Betty Irene Moore Children’s Heart Center. It has been the flagship surgery in our PAR program since the mid-1990s. In the last 20+ years, we have built an entire team of exceptionally talented cardiothoracic surgeons who perform unifocalization, and we have expanded the techniques of unifocalization to other heart-lung conditions and developed other reconstruction procedures.

The individuals that we treat in our PAR program have complex congenital (present at birth) or acquired (after birth) heart defects accompanied by pulmonary artery abnormalities. Children and adults from across the globe come to us for our one-of-a-kind, exceptional care. We welcome you to learn more about our PAR program, a core strength of our nationally leading Betty Irene Moore Children’s Heart Center.
