Todd J. Brinton, MD

Dr. Brinton is an instructor of medicine (cardiovascular medicine) at Stanford University School of Medicine. He completed his BS in biomedical engineering at the University of California, San Diego and his doctorate in medicine at the Chicago Medical School. Dr. Brinton completed his internship and residency training in internal medicine at Stanford. He then completed a clinical cardiology fellowship and clinical investigator research fellowship at Stanford. He completed a subspecialty fellowship in interventional cardiology at Stanford in 2006.

Dr. Brinton is board certified in internal medicine and cardiovascular medicine. His clinical expertise is in interventional cardiology with an emphasis on new device strategies for percutaneous coronary interventions. Dr. Brinton has a specific interest in the development of new technologies for treatment of cardiovascular disease. Dr Brinton also serves on the executive faculty of the program in biodesign within the Department of Bioengineering at Stanford.

Dr. Brinton's academic research focuses on the development and evaluation of minimally-invasive techniques for cardiac stem cell transplantation and imaging techniques for assessment of cell viability after transplant in pre-clinical models. He currently directs several clinical trials of interventional-based therapies for chronic ischemia and heart failure.

Specialties: Coronary artery disease, Chronic ischemic heart disease, Novel therapies for revascularization & restoration of ischemic heart failure.

William F. Fearon, MD

William F. Fearon, MD

Dr. Fearon is an associate professor of medicine (cardiovascular medicine) at Stanford University School of Medicine.

Dr. Fearon received his BA from Dartmouth College and his MD from Columbia University, College of Physicians and Surgeons.

He completed a residency in internal medicine at Stanford and served as medical chief resident. He then completed a cardiology fellowship and an interventional cardiology fellowship also at Stanford, and has been on faculty at Stanford since 2002. He is board certified in cardiovascular medicine and interventional cardiology.

Dr. Fearon's research focus is on coronary physiology and measuring indices such as fractional flow reserve and the index of microcirculatory resistance to improve patient care. His clinical expertise is in percutaneous coronary intervention and transcatheter aortic valve replacement.

Specialties: FFR, PCI, TAVR

David P. Lee, MD

David P. Lee, MD

Dr. Lee is an assistant professor in medicine and his research includes brachytherapy, vascular remodeling, new treatment strategies for acute myocardial infarction, and coronary venous mapping.

Specialties: ASD/PFO closure, Alcohol septal ablation


Jennifer A. Tremmel, MD, MS

Jennifer A. Tremmel, MD, SM

Dr. Tremmel is the clinical director of the Women’s Heart Health program. She is an interventional cardiologist who also trained in preventive cardiology. In her clinic she cares for women who are at high risk for coronary artery disease, women who have symptoms concerning for heart disease, and women who already have heart disease. She has a particular interest in women who present with symptoms of heart disease, but are found to have "normal" coronary arteries on angiography. Her current research investigates whether women presenting like this are more likely than men to have coronary abnormalities that cannot be detected by angiography alone, such as endothelial dysfunction, diffuse deposition of plaque, or microvascular disease.

Dr. Tremmel received her bachelor's degree in psychology and her medical degree from the University of Iowa. She did her internal medicine internship and residency at Dartmouth-Hitchcock Medical Center. Following that she obtained a master’s degree in epidemiology at the Harvard School of Public Health. She completed her fellowship in cardiovascular medicine and interventional cardiology at Stanford University Medical Center, where she was also a postdoctoral research scholar at the Stanford Prevention Research Center.

Specialties: Interventional cardiology, Preventive cardiology

Alan C. Yeung, MD

Alan C. Yeung, MD

Dr. Yeung is an interventional cardiology professor of medicine, director of interventional cardiology and chief of the Division of Cardiovascular Medicine (clinical).

He graduated from Harvard Medical School in 1984 and received his training in cardiology at the Brigham and Women's Hospital in Boston.

Dr. Yeung came to Stanford in 1993. His research interests include coronary artery remodeling, acute coronary syndromes, new device development as well as novel approaches to coronary revascularization including stem cell therapy.

Specialties: Complex coronary interventions, Mitral valvuloplasty
