Mehran Massumi, MD

After completing his residency in 2013, Dr. Massumi began a fellowship program in cardiovascular diseases at The Texas Heart Institute at Baylor St. Luke’s Medical Center, which he completed in 2016. He followed with a dedicated advanced fellowship in interventional cardiology at The Texas Heart Institute, which he completed in 2017. Show full bio

Between 2008 and 2017, Dr. Massumi was involved in several research projects, including: to perform BAV (balloon aortic valvuloplasty) or not, that is a TAUR (transcatheter aortic valve replacement) question; effect of botulinum toxin on inducibility and maintenance of atrial fibrillation in ovine myocardial tissue; endovascular treatment of superior vena cava syndrome secondary to pacemaker placement using balloon in balloon venoplasty and palmaz stent; prediction of imminent endocardial perforation via specific alterations of measurable and calculable variables at the catheter tip/endocardial interface; and the outcome of breast reduction surgery on quality of life regardless of amount resected or patient weight.

Dr. Massumi joined Kelsey-Seybold in June 2017, where he previously worked in the Lipid Clinic for a year (in 2004) between completion of his undergraduate degree in biology and the start of medical school, researching patient charts and conducting patient interviews.​
