Suneet Mittal, MD – Director

Director of Electrophysiology; Medical Director of The Snyder Center for Comprehensive Atrial Fibrillation; Director of Cardiac Research

Make an Appointment

With more than 20 years of experience in treating patients with heart rhythm disorders, Dr. Mittal is recognized as one of the foremost cardiac electrophysiologists and researchers. Highly skilled in the development, usage, and evaluation of advanced procedures and new devices to treat arrhythmias – heartbeats that are too fast, too slow, or irregular – Dr. Mittal is also eminently compassionate and supportive to all his patients and their loved ones. Espousing a team approach to care, Dr. Mittal practices evidence-based, patient-centered heart care that relies upon each member of the team to provide his/her optimal recommendations for achieving the best possible patient outcomes.

Board-certified in cardiovascular disease and clinical cardiac electrophysiology, Dr. Mittal specializes in the diagnosis, treatment, and management of all types of arrhythmias and associated conditions. These include atrial fibrillation, atrial flutter, supraventricular tachycardia, atrial tachycardia, and ventricular tachycardia/fibrillation. His expertise also includes treating unexplained palpitations (irregular or facing heartbeats), unexplained stroke and syncope (fainting), cardiomyopathy, and cardiac arrest.

Dr. Mittal is highly skilled and sought after to perform minimally invasive or non-invasive procedures to implant cardiac devices to diagnose, manage, and prevent arrhythmias, including implantable loop recorders, left atrial appendage closure and ligation, permanent pacemakers (leadless, single- and dual-chamber pacemakers), His-bundle pacing, cardiac resynchronization therapy, implantable cardioverter defibrillators (ICDs), and the full spectrum of remote patient monitoring devices for 24/7/365 coverage.

His expertise also lies in performing advanced robotic and minimally invasive catheter ablation procedures, which utilize thin tubes threaded from the patient’s groin into the heart. The tip of the catheter delivers radiofrequency or cryo energy to the site, thus destroying abnormal electrical impulses and restoring the heart to a normal rhythm. Dr. Mittal has been instrumental in developing and perfecting many of these ablation procedures, which include three-dimensional mapping, robotic catheter navigation, cryo and radiofrequency energy-based ablation, focal impulse and rotor mapping (FIRM), and hybrid ablation.

Throughout his medical career, Dr. Mittal has been engaged in clinical research to evaluate and manage known or suspected arrhythmias in patients. His interests range from assessing patients with atrial fibrillation and unexplained syncope to the role of implantable monitors to overcoming barriers to remote patient monitoring. He currently is the principal investigator for a number of studies to assess the use of cardiac loop recorders and serves on several industry-related committees to evaluate research results.

Dr. Mittal has shared his expertise with cardiac electrophysiologists and other heart care specialists all over the world at major academic institutions in the United States, Europe, and India. For many consecutive years, he has been an invited faculty member at the annual scientific sessions of the American Heart Association, the American College of Cardiology, and the Heart Rhythm Society. For the past several years, he has taught at co-sponsored conferences of Valley Health System and the Cleveland Clinic at The Valley Hospital. Dr. Mittal also serves as a co-ambassador to India for the Heart Rhythm Society. He is a member of numerous medical committees of Valley Health System and professional heart organizations. He is a co-editor, invited reviewer, and member of the editorial boards of the leading peer-reviewed journals of cardiology and electrophysiology. He is also the author of more than 200 books, abstracts, and book chapters.

Dr. Mittal received his medical degree magna cum laude from Boston University School of Medicine.
