 I'm Beverly, and that's what I was facing when my cardiology team at Northwestern Medicine identified a diseased valve in my heart. But thanks to Dr. Gang and Dr. Ahmad's expertise, I didn't have to have open-heart surgery. With access to the top heart and vascular program in Illinois by U.S. News & World Report, Beverly's team at Central DuPage Hospital replaced her diseased aortic valve using a tiny catheter, and she was back on her feet in just a few days. Northwestern Medicine. Better.
