Kolkata: BM Birla Heart Hospital conducts successful dual-chamber leadless pacemaker implantation

The milestone procedure was performed by Dr. Anil Mishra, Director of Cardiology, BM Birla Heart Hospital.

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

What is 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.

The successful dual-chamber leadless pacemaker implantation at BM Birla Heart Hospital marks a transformative moment for cardiac patients in the region.

The hospital said the breakthrough ensures that patients from Eastern India no longer need to travel to other metros or abroad for advanced heart rhythm therapies.

Dr. Anil Mishra describes AVEIR as a 'revolution'

The hospital’s cardiology team, led by Dr. Anil Mishra, is also training other cardiologists across the country in this revolutionary technology to expand its reach and availability across India.

“This is a defining moment in the evolution of cardiac pacing,” said Dr. Anil Mishra, Director of Cardiology, BM Birla Heart Hospital.

“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," he said.

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.
• Minimally invasive procedure: Shorter hospital stay and faster recovery.
• 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 and 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.
