A Legacy of Heart Care



In honor of American Heart Month, we celebrate Dr. Willis J. Potts, a pioneer cardiac surgeon at Children’s Memorial Hospital. He became internationally known for his surgical creation of direct aortopulmonary connections for babies with severe cyanotic congenital heart diseases. These diseases are commonly referred to as “blue baby syndromes,” which comes from the color of the deoxygenated blood circulating through the babies’ bodies.

On September 13, 1946, Diane Schnell (shown in the photo with Dr. Potts) became the first patient to undergo a historic aortopulmonary anastomosis. The procedure was made possible by a special vascular clamp developed by Potts, which he perfected the use of with Caesar, the dog in the photograph. After the surgery, Diane recovered quickly and left the hospital 19 days later.

Patients from across the United States and beyond came to Children’s Memorial for this lifesaving procedure, building Dr. Potts’ international acclaim. When Dr. Potts joined Children’s Memorial‘s staff in 1930, there was only one pediatric surgeon in the United States; by his retirement in 1960, there were 75.

In an article that appeared in the June 1956 edition of The Journal of the American Medical Association, Dr. Potts wrote about his views on the pediatric heart: “The physical heart of a child is just a piece of living muscle marvelously adapted to its sole function of pumping blood. It is a rugged mechanism that will tolerate the ravages of infection, the scars resulting from impaired blood supply, and the approaches of surgeons’ tools. It is the most efficient self-sustaining pump in the world. In a philosophical sense, the heart of a child is a delicate mechanism, sensitive to the slightest wounds of fear, insecurity, indifference, thoughtlessness, and misunderstanding.” 

The Willis J. Potts Heart Center was established in 1964, ensuring that the Potts legacy would live on. This year, the Heart Center at Lurie Children’s celebrates its 50th anniversary.
