About me

John Conte, MD, is a highly experienced and accomplished cardiovascular surgeon at MedStar Union Memorial Hospital with over 30 years of experience. He is known for his expertise in treating aortic, coronary artery, and heart valve disease, often performing complex and re-operative surgeries.

 A pioneer in his field, Dr. Conte was the first in Pennsylvania to use the HAART aortic valve ring, which is now commonly used. Additionally, he contributed to an early body of research that led to technologies like artificial hearts and heart pumps. A strong advocate of the safe integration of new technologies, he firmly believes it is a physician's responsibility to help clients navigate the world of developing technologies to determine the best option for their clinical situation and long-term health goals.

A strong advocate for the safe integration of new technologies, Dr. Conte firmly believes it is a physician's responsibility to help clients navigate the world of developing technologies to determine the best option for their clinical situation and their long-term health goals. He pays close attention to evolving technologies that will allow surgeons to do less invasive valve repairs and replacements and incorporates them into his clinical practice.

Dedicated to advancing cardiovascular knowledge and improving outcomes, Dr. Conte was integral in founding the Maryland Cardiac Surgery Quality Initiative (MCSQI) and served as its first president. The MCSQI’s mission is to bring surgeons from across the state together to share, review, and analyze data to improve patient outcomes and lower patient surgery costs. This organization focuses on collaboration versus competition and is moving the needle to ensure that every patient in Maryland receives the best care possible, regardless of location or means.

Dr. Conte completed his medical training and residency in general surgery at Georgetown University, followed by fellowship training in cardiothoracic surgery at Stanford University. His professional career began at the University of Maryland in 1995, where he held leadership positions. Later, he spent 20 years at Johns Hopkins Hospital before assuming the role of Chair of Cardiothoracic Surgery and Vice Chair of the Geisinger Heart Institute in 2020.

Throughout his long career, Dr. Conte has belonged to and held leadership positions in all the major cardiological society organizations. He is a Fellow of the American College of Surgeons, the American College of Chest Physicians, and the American College of Cardiology. He has received numerous honors and awards, including a Meritorious Achievement Award in 2019 from the Maryland Cardiac Surgery Qualitative Initiative.

Philosophy of Care

“After decades of being away from Maryland, I am excited to return to my home where it all started. As an experienced practitioner, I look forward to being a part of a fantastic team of physicians who are dedicated to building and developing the program at MedStar Health.

“Once I take on a patient, I do everything possible to ensure they have the best shot possible to heal and recover. I want my patients to know that I am experienced, and  more importantly, I will do what is best for them, no matter what.”
