About Stephan Danik, MD, MPH

Dr. Danik was born and raised in New Jersey.  He attended Rutgers University and received his MD degree from the New Jersey Medical School in Newark, NJ.  He completed his internship and medical residency at Columbia Presbyterian Medical Center in New York.  After completing his general cardiovascular fellowship  at the Mount Sinai Medical Center in New York, he spent the final two years of his training in cardiovascular electrophysiology at the Massachusetts General Hospital in Boston.  He earned a master of science in clinical investigation from Massachusetts Institute of Technology and, he joined the staff of the cardiovascular electrophysiology division at MGH in 2007.

Dr. Danik is the director of the experimental electrophysiology laboratory where he is able to pursue his research interests that include imaging the substrate of ventricular tachyarrhythmias.  His clinical interests also include development of catheter based technologies and device infections.

Research

My current area of research includes both experimental and clinical areas of work.

Experimentally, we are using novel imaging modalities such as PET-CT in the large animal model to help visualize the circuits which are responsible for ventricular tachycardia and sudden death.  We were fortunate to obtain a Harvard Catalyst Grant to help in this endeavor. 

On the clinical side, we are involved in ongoing research in pacemaker and defibrillator infections and understanding the risk factors in this pathological process as well as the optimal treatment modalities.  We are part of a large multicenter study sponsored by the American Heart Association.

We are also investigating the role of magnetic resonance imaging (MRI) in patients who have undergone pulmonary vein isolation for the treatment of atrial fibrillation.  We hope to be able to use MRI to predict which patients are at risk stratification for the success or failure of the procedure to allow for a better decision making process as to the optimal form of therapy for atrial fibrillation.

Finally, we are part of the process in understanding which patients with sarcoidosis are at high risk for ventricular tachyarrhythmias and sudden cardiac death.  We are part of a multicenter study that is investigating which patients are most likely to benefit from defibrillator implantation for the prevention of sudden cardiac death.

Excellent vist


April 2025

the experience was fine but i didnt understand what took so long to do it. ive had them before and it only took about 20 minutes this time over an hour. they tried to explain but i didnt understand what she was saying. she said she couldnt see my heart. i know its my own experience that was to blame since this is the best hospital on the planet.

He is an outstanding Doctor and MGHis fortunate to have him.


March 2025

Dr. Danik performed my ablation, he has and will continue to follow my overall progress in the coming months. It's always a pleasure meeting with him; his wealth of knowledge cannot be overstated. [redacted]


February 2025

My husband had Dr. Danik to serve as his pacemaker and we just really, really liked him. He was very thorough. He was very nice and we just really had a great experience with him.


February 2025

Dr. Danik is fantastic. He's knowledgeable, thorough, and compassionate. He listens carefully to my concerns and always takes my ideas about treatment options into account while clearly explaining the rationale for his recommendations. His treatment of my a-fib has been exemplary, including a successful cardiac ablation. I have recommended Dr. ... Read More

Dr. Danik is a wonderful physician.


February 2025

very positive experience


February 2025

Dr.Danik went over all the mechanics of ICD and Pacemaker. We didn't have enough time to go over side effects on the first consultation but I assume we will prior to procedure. I research anyway so know what's coming. What I liked was the references to statistics that helped me decided what to do and possible (but not certain) benefits.


January 2025

It was quite.
