    Vivek Y. Reddy, MD is Director of Cardiac Arrhythmia Services for The Mount Sinai Hospital and the Mount Sinai Health System, and The Leona M. and Harry B. Helmsley Charitable Trust Professor of Medicine in Cardiac Electrophysiology at Icahn School of Medicine at Mount Sinai.

    Dr. Reddy is one of the nation’s premier cardiac electrophysiologists, leading a team of physician-scientists who are developing and testing advanced therapies for cardiac arrhythmias – including atrial fibrillation and ventricular tachycardias, the most common cause of sudden cardiac death.   His team offers the full spectrum of arrhythmia therapies.

    Dr. Reddy’s pioneering clinical research is changing the way cardiac patients are treated and cured.  Under his leadership, Mount Sinai is the lead investigator on several multinational clinical trials exploring new arrhythmia procedures and technologies.

    In addition, in 2014 Dr. Reddy implanted inside a patient's heart the world’s first miniature leadless pacemaker in the United States at The Mount Sinai Hospital.

Catheter Ablation of Atrial Fibrillation (AF)

AF is the most common heart arrhythmia. Medications are only modestly effective, so we are working on catheter-based approaches to treat AF by directly cauterizing the tissue causing the problem. We are working with other approaches to do this catheter ablation procedure using laser energy or cryo energy (freezing tissue).

Left Atrial Appendage Closure

People with AF are at high risk for stroke-thus most people receive Warfarin Rx. We are working on approaches to use catheters to close the left atrial appendage. Then, patients would be protected from stroke without having to take Warfarin (Coumadin).

Catheter Ablation of Ventricular Tachycardia (VT)

Ventricular tachycardias are the most common cause of sudden death. The standard approach is to place defibrillators (ICDs) in patients at high risk for sudden death. We are working on approaches to use catheters to cauterize (ablate) the tissue responsible for these arrhythmias.
