Chetan Pasrija, M.D. is a cardiothoracic surgeon in Baltimore, Maryland. He is an assistant professor of surgery at the Johns Hopkins University School of Medicine. Dr. Pasrija specializes in heart and lung transplantation, aortic surgery, and the surgical treatment of ischemic heart disease. He also has a particular interest in chronic thromboembolic pulmonary hypertension. He has published extensively on the topics of heart and lung transplant, massive pulmonary embolism, chronic thromboembolic pulmonary hypertension, and minimally invasive left ventricular assist device implantation. As a trainee, Dr. Pasrija was heavily involved with the surgical implantation and postoperative management of the first cardiac xenotransplant performed in the world at the University of Maryland. During his time as faculty at Vanderbilt University, he was a part of one of the largest heart and lung transplant programs in the United States. This included significant involvement with cutting-edge technologies to expand the donor pool, including normothermic regional perfusion and the Transmedics Organ Care System. Dr. Pasrija was co-surgeon in a combined heart-lung transplant with a groundbreaking 9.5 hour period of time without any blood flow using a novel 10⁰C cooler. He has also performed heart transplants with travel as far as Puerto Rico.Outside of transplantation, Dr. Pasrija is a high-volume cardiac surgeon, with an interest in complex open and endovascular aortic surgery. He performed the first ascending stent in the state of Tennessee, as well as the first total arch replacement without cooling the patient’s body in Tennessee using the Thoraflex device. He earned his Bachelor of Science Degree in Bioengineering at the University of Maryland and his Medical Degree at the University of Maryland School of Medicine. He completed an Integrated Cardiothoracic Surgery residency at the University of Maryland. During his training, he spent time at Vanderbilt University to learn advanced heart failure techniques as well as time at the University of Toronto to learn advanced lung transplant and pulmonary thromboendartectomy techniques. Additionally, he has a Masters in Clinical Research from the University of Maryland. Outside of his clinical interests, Dr. Pasrija is an accomplished investigator. During his post-doctoral research fellowship, he received a competitive American Heart Association post-doctoral fellowship award in addition to institutional awards for excellence in research. His research efforts focus on improving donor preservation with novel perfusion and temperature techniques, improving donor evaluation methods, and establishing novel immunologic therapies for transplant tolerance.
