Kolkata: BM Birla Hospital conducts successful retrieval of 7-year-old leadless pacemaker in elderly patient

Dr. Anil Mishra, who performed the complex procedure, said the case represents another milestone for the institute’s cardiology department.

“At BM Birla, we have consistently introduced new techniques and achieved several firsts in the field of cardiology,” Mishra told reporters.

The elderly patient had a long and complicated cardiac history, compounded by multiple comorbidities, making the procedure particularly challenging.

“Leadless pacemakers were designed to minimise many of the complications associated with traditional transvenous systems. However, their long-term management continues to evolve,” Mishra explained.

He noted that retrieving a device implanted for several years can be technically demanding due to fibrotic encapsulation — a process in which scar tissue forms around the device, making extraction uncertain.

“When a device has been in place for an extended period, fibrotic fixation can make retrieval highly complex. Careful preparation is crucial — assessing the degree of fixation, anticipating potential complications, and ensuring pacing backup at every stage,” the doctor said.

The procedure required controlled traction, precise catheter manipulation and continuous haemodynamic monitoring throughout.

“These are not routine interventions. They demand a coordinated team,” Mishra added.

According to Mishra, there has been no prior documentation in India of a successful extraction of a leadless pacemaker beyond the early one-week post-implant period.

He said the patient has recovered well, with post-procedure imaging confirming satisfactory positioning and function, and added that the case provides renewed confidence to the medical community regarding the long-term use and management of leadless pacemakers.

“We now have greater assurance that we do not need to crowd the heart with multiple devices,” he said.
