Leadless Pacemaker Implantation in Chennai

Most leadless pacemakers last between 8 to 12 years, depending on how often the device delivers pacing pulses (which varies by the patient's heart rhythm) and how the device is programmed. Dr. Deep Chandh Raja will monitor the battery status at every follow-up visit and advise you well in advance when a replacement is needed.

The cost of leadless pacemaker implantation in Chennai varies depending on the type of device (e.g., Micra or AVEIR), the hospital facility, and the patient's overall condition. It is generally higher than a conventional pacemaker due to the advanced technology involved. Your cardiologist will recommend the most suitable device and provide a detailed cost estimate based on your specific treatment plan. Please contact our team for a personalised quote.

An experienced cardiac electrophysiologist is the right specialist for leadless pacemaker implantation — not just a general cardiologist. Dr. Deep Chandh Raja at Chennai Heart Rhythm Trust is recognised as one of the highest-volume implanters of leadless pacemakers in South India. He is internationally trained, serves as a proctor for other cardiologists across India, and practices at Kauvery Hospital Alwarpet and Kauvery Hospital Vadapalani.

Yes, leadless pacemaker implantation is considered very safe — and in many ways safer than a conventional pacemaker. Because there are no leads (wires) or a surgical pocket under the skin, the risks of lead fracture, lead dislodgement, and wound infection are eliminated entirely. The procedure is performed through a small access point in the groin vein, requires no chest incision, and has a high success rate when performed by an experienced cardiac electrophysiologist like Dr. Deep Chandh Raja.

No. The leadless pacemaker is approximately the size of a large vitamin capsule and is placed entirely within the heart muscle. There is no visible bulge under the skin, no scar on the chest, and no sensation from the device itself. Most patients are not aware of its presence at all once they have recovered from the procedure.

Yes. While the leadless pacemaker is designed to remain in the heart permanently, it can be turned off remotely if no longer needed. In cases where the battery is depleted or the device needs to be upgraded, a new device can be implanted alongside the existing one. Retrieval of the old device is also possible in most cases, particularly when performed by an experienced specialist soon after implantation.

Recovery is significantly faster than with a traditional pacemaker. Most patients go home within 24 hours of the procedure. You will be advised to avoid strenuous activity and heavy lifting for 1–2 weeks, but most normal daily activities — including bathing, walking, and light work — can resume within a few days. There are no arm movement restrictions as there are with conventional pacemakers, since no leads pass through the shoulder area.

Yes. Current generation leadless pacemakers such as the Micra and AVEIR are MRI-conditional, meaning MRI scans can be safely performed under specified conditions. This is a significant advantage over older conventional pacemakers, many of which were incompatible with MRI. Your doctor will advise the radiology team of your device details before any scan.

Unlike traditional pacemakers, a leadless pacemaker places no restrictions on arm or shoulder movement. Within a few days you can resume light activities, driving (once cleared by your doctor), and regular exercise. Avoid high-impact contact sports or very heavy lifting for the first 2 weeks. Swimming, yoga, and most recreational activities are generally permitted after full recovery. Dr. Deep Chandh Raja will provide personalised activity guidance based on your heart condition.
