As Jimmy Kimmel movingly revealed on his show Monday night, his newborn son underwent emergency open-heart surgery just days after his birth.

A perceptive nurse probably saved the child’s life by noticing the early signs that the child had a congenital heart defect called tetralogy of Fallot.

This heart condition prevented Kimmel’s son’s lungs from getting enough oxygen, requiring surgery. The procedure was a success, but a second operation will be required in a few months and a third when Kimmel’s son is a teenager.

Congenital heart defects occur in just under 1 percent of babies. Of those, 10 percent have tetralogy of Fallot. (The odds of Kimmel’s son’s specific condition are about 1 in 10,000.)

The causes of heart defects are generally not understood. While surgeries have a high success rate, the procedures are a treatment, not a cure. As Dr. Joseph Rossano, executive director of The Cardiac Center at Children’s Hospital of Philadelphia, puts it: “We can definitely treat it, and many patients live with these conditions and do very well. But they do need lifelong care.”
