About John R Spratt

My name is John R Spratt, MD, and I am a clinical assistant professor of thoracic and cardiovascular surgery. My inspiration to go into medicine came from my parents; my father is a cardiothoracic surgeon and my mother is a nurse. My decision to become a thoracic and cardiovascular surgeon was solidified during my time as a medical student and general surgery resident, where I participated in the care of critically ill cardiac and thoracic surgical patients.

I treat patients with the full breadth of adult cardiac surgical disease, including coronary artery disease, mitral and aortic valve disease, atrial fibrillation, aortic aneurysm and dissection, and atrial fibrillation. I also have a particular interest in catheter-based valve therapies, including TAVR, TEER, and TMVR, and moderate our weekly multidisciplinary valve conference.

I earned my medical degree from the Medical University of South Carolina. I then completed my residency in general surgery at the University of Minnesota Medical School, where I served as administrative chief resident during my final year. Following my residency, I completed fellowship training in thoracic and cardiovascular surgery at the University of Florida College of Medicine. I am certified by the American Board of Surgery and American Board of Thoracic Surgery.

I am committed to understanding each patient’s specific situation to help them make the best possible decisions about their care. I enjoy reviewing imaging studies, talking to patients and their families, and examining all the possibilities to ensure we make the correct diagnosis and construct an appropriate treatment plan for each patient. My research interests include the use of cerebrospinal fluid drains and other measures used in open and endovascular aortic surgery for the prevention of spinal cord ischemia.

Outside of work I enjoy reading, exercising, and spending time with my wife, Claire. Our hobbies include yoga, Formula 1 racing, cooking, and exploring Florida.
