Adult Congenital Heart Disease

Harsimran Singh, MD and Jillian Nati, NP

Adult Congenital Heart Disease at Weill Cornell Medical College

Congenital heart disease is the most common form of birth defect. Thanks to modern-day advances in medical and surgical care, most children born with serious congenital heart defects survive long into adulthood.

In the US, there are now more adults with congenital heart disease than children. This is evidence of phenomenal medical successes, but also means that many adults with congenital heart disease require lifelong care to live a long and healthy life.
