Cardiac Arrhythmia Center

View Patient Story

We are one of the highest-volume centers for complex cardiac arrhythmia procedures in the country

The Cardiac Arrhythmia Center at Montefiore Einstein Center for Heart and Vascular Care is a respected leader in the diagnoses, treatment, and research of heart rhythm conditions. Known for our excellence in the field, we are an international referral site for procedures such as catheter ablation and cardiac device implantation. We also serve as a rigorous educational facility for medical fellows, and we take great pride in training the next generation of innovative electrophysiologists. Likewise, we are conducting one of the largest multicenter randomized control trials in atrial fibrillation in the world.

Doing More

Atrial fibrillation is an irregular heart rate that can lead to stroke and heart disease. To treat such cases, the Cardiac Arrhythmia Center performs an extensive ablation, a procedure which destroys the cardiac tissue responsible for the abnormal heart rhythm. We target sites associated with triggers originating outside of the pulmonary veins, such as the entire posterior wall, the roof, the anterior part of the left atrium, the left atrial appendage (LAA), the coronary sinus, and the superior vena cava. When combined with pulmonary vein isolation, this procedure dramatically decreases atrial fibrillation in patients in the long term.

This technique has dramatically improved clinical outcomes and decreased the risk of complications.

The Cardiac Arrhythmia Center is one of the only centers in the world currently performing complete fluoroless catheter ablation for ventricular tachycardia, atrial fibrillation, and supraventricular tachycardia. This approach eliminates exposure to ionizing radiation.

The Cardiac Arrhythmia Center, under the direction of world-renowned Dr. Kalyanam Shivkumar, MD, PhD (UCLA),  is the only program in the Northeastern United States that performs autonomic modulation for the treatment of life-threatening ventricular arrhythmias.

This program helps to reduce the risk of stroke in patients with atrial fibrillation who have a high risk of bleeding, falls, or poor compliance to blood thinners.

Cannulating the coronary sinus and finding an adequate branch to place the LV lead presents challenges. By employing a procedure known as His bundle pacing (HBP), we can achieve near-perfect ventricular synchrony.

The Cardiac Arrhythmia Center has collaborated with Dr. Gregory Michaud (Vanderbilt University) on the development of a technique which uses low power and low irrigation rates in the posterior wall to avoid complications, such as atrial esophageal fistulae.
