About Me

I specialize in Interventional Cardiology and Structural Heart Disease.

Medical Director, Henry Ford Center for Structural Heart Disease

Dr. O’Neill, is an internationally recognized leader in Interventional Cardiology and Structural Heart Disease, as well as a pioneer in research and new techniques to diagnose and treat heart disease. Dr. O’Neill is one of about two-dozen Master Fellows out of 4,500 world-wide members of the Society for Cardiovascular Angiography and Interventions (MSCAI), the professional medical society for invasive and interventional cardiologists. He pioneered the use of angioplasty for treatment of heart attacks, which is now the mainstay therapy throughout the world. He performed the first transcatheter aortic valve replacement (TAVR) in the U.S. in 2005. Currently he is organizing new protocols to treat a deadly side-effect of massive heart attacks. The Detroit Cardiogenic Shock Initiative increases patient survival rate from 50% to 80%.

A leader in academic and teaching hospitals for nearly 30 years, and to date, an author of more than 300 hundred peer-reviewed articles and abstracts published in medical literature, Dr. O’Neill has written multiple book chapters, and edited one of the first textbooks in the field of interventional cardiologists. He was a founding member of the American Board of Internal Medicine interventional cardiology board, which certifies all interventional cardiologists.
