Rabindra Nath Tagore Heart Institute Sets a Landmark in Eastern India with Successful Dual-Chamber Leadless Pacemaker Implantation

Kolkata, October 11, 2025: In a pioneering advancement in cardiac care, Rabindra Nath Tagore Heart Institute, Kolkata, has become the first centre in Eastern India to successfully implant two dual-chamber leadless pacemaker on the same day on 8th October (the most advanced and latest technology in cardiac Pacemaker devices), marking a major leap forward in the management of heart rhythm disorders. The milestone procedure was performed by Debdatta Bhattacharyya, of cardiologists and technical experts in the Cathlab at NH (RTIICS).

This achievement places Rabindra Nath Tagore Heart Institute at the forefront of cutting-edge cardiac rhythm management technologies, reaffirming its position as a leader in advanced and minimally invasive cardiac interventions.

Revolutionising Heart Rhythm Management with AVEIR Technology

The newly introduced AVEIR leadless pacemaker system represents the next generation of pacing technology. Unlike conventional pacemakers that require surgical implantation with wires (leads) and a chest pocket, the AVEIR system is entirely wireless and minimally invasive.

The pacemaker, approximately the size of a vitamin capsule is implanted directly into the heart through a thin catheter inserted via a vein, eliminating the need for chest incisions or visible scars. This approach significantly reduces post-surgical discomfort, infection risk, and recovery time.

With an expected lifespan of 18–20 years or more, the AVEIR pacemaker sets new standards in reliability and long-term patient comfort. It is available in both single and dual-chamber models, allowing cardiologists to customise therapy based on each patient’s unique heart rhythm needs.

A First for Eastern India — A Step Towards the Future

The successful dual-chamber leadless pacemaker implantation at Rabindra Nath Tagore Heart Institutemarks a transformative moment for Cardiac patients in India placing it amongst the forefront of advanced cardiac rhythm management in the whole country.

“This is a defining moment in the evolution of cardiac pacing.” said Debdatta Bhattacharyya, Consultant Cardiologist Chief of Cathlab & Clinical Director NH RTIICS.“The AVEIR system is not just an innovation,it’s a revolution in cardiac rhythm management. It brings global-level precision, safety and simplicity to Indian patients, ensuring a faster recovery and a better quality of life.”

International Expertise Joins the Milestone

Adding to the significance of the event, Dr. Cyrus Adel Hadadi, Associate Director of Cardiac Arrhythmia, MedStar Heart & Vascular Institute, USA, shared insights into leadless pacemaker technologies.

Dr. Hadadi is a globally recognised expert in this field, having successfully performed over 500 dual-chamber (DR), 150+ atrial (AR), and 300+ ventricular (VR) leadless pacemaker implants. His presence highlights the growing collaboration between Indian and international experts in advancing cardiac innovation and patient outcomes.

Key Advantages of the Leadless AVEIR Pacemaker

• Size of the Pacemaker: each smaller than an AAA battery.

• No Wires, no Chest Incision: Entirely leadless technology inserted through a vein, leaving no visible scar.

• Long-Lasting Performance: Up to 20 years of functionality, reducing the need for replacements.

• Reduced Infection Risk: No chest pocket or external leads that can cause complications.

• Comfort & Mobility: Lightweight, capsule-sized device that patients don’t even feel after implantation.

• Dual-Chamber Capability: First-of-its-kind system that synchronises both heart chambers wirelessly for natural rhythm control.
