About the Provider

John C. Wang, MD, is chief of the Cardiac Catheterization Laboratory at MedStar Union Memorial and scientific director for Baltimore Cardiovascular Research. Dr. Wang is board certified in Interventional Cardiology, Cardiovascular Disease and Internal Medicine. He specializes in minimally invasive procedures that increase blood flow to the heart, diminish chest pain and decrease the risk of heart attack.

Dr. Wang and his team perform more than 5,000 procedures a year. He finds great satisfaction in how quickly a patient's quality of life improves with the latest techniques in angioplasty, stenting and catheterization. Using an advanced procedure known as transradial cardiac catheterization, performed through the patient's wrist, Dr. Wang is able to offer patients a less-invasive, safer option than traditional catheterization, as well as a quicker recovery time and shorter hospital stay. Dr. Wang also performs transcatheter aortic valve replacements (also known as TAVR). He replaces a patient's aortic valve via a small catheter placed through the femoral artery without traditional open-heart surgery. MedStar Union Memorial is one of the few hospitals in the region to offer these procedures.

Dr. Wang's passion for clinical research helps improve the lives of patients. Widely published, Dr. Wang has been the principal investigator or sub-investigator on more than 40 studies relating to the safety and efficacy of new devices and technology in interventional cardiology. Currently, he is the national principal investigator of the OMEGA trial studying the latest generation of bare metal stents.

Before his medical training, Dr. Wang received his undergraduate degree from the University of Chicago. He also earned a Master's of Science in Epidemiology from the Harvard School of Public Health.

John Wang, MD, named 2020 "Top Docs" by Baltimore magazine for interventional cardiology.
