Dr. Kimmelstiel is the Director of the Cardiac Catheterization Laboratories and Interventional Cardiology at Tufts Medical Center and is a Professor of Medicine at Tufts University School of Medicine in Boston. He trained at Downstate Medical Center-Kings County Hospital, the University of Massachusetts Medical Center and Tufts Medical Center. 

Early in his career, Dr. Kimmelstiel’s academic interest focused on heart failure. Subsequently, he turned his interest to mechanistic studies focusing on the effect of various pharmacologic agents on platelet function during PCI. More recently, he has focused on structural cardiac interventions, primarily alcohol septal ablation for hypertrophic obstructive cardiomyopathy and PFO closure.  Dr. Kimmelstiel was among the earliest interventionalists to perform alcohol septal ablation for HCM. He was also among the first to advance the techniques employed in this procedure by targeting the correct sub-branch vessel with contrast echocardiography allowing smaller doses of ethanol to be used. He is routinely invited to major national and international meetings to lecture on this topic. He has also been at the vanguard in the implantation of PFO/ASD closure devices for cryptogenic strokes or migraines. His volume of implants led the way in the major national trial which led to the FDA approval of this procedure.  

Dr. Kimmelstiel enjoys clinical research, both as a participant and administrator having served on, or chaired, dozens of clinical events committees and data and safety monitoring boards. He takes pride in collaborating with colleagues to perform novel procedures within the catheterization laboratory which has led to programs in PFO closure, alcohol septal ablation for HCM and even delivery of babies to mothers with high-risk cardiovascular disease. 

Professionally, Dr. Kimmelstiel is most proud of the fellows that he has helped to train. He is honored to have received many teaching awards, including most recently the Dedication to Teaching Award from his former Interventional Cardiology Fellows. An example of his mentoring and the lasting impact on trainees was his development of an mobile app in which he and former trainees can share coronary angiograms with one another, to exchange advice on approach to complex interventions. Several recent graduates at once can be tuned in to the text discussion, and exchange opinions and thoughts, with Dr. Kimmelstiel weighing in on their thinking. It is a truly impressive example of “lifelong mentoring”.
