The Lead Episode 52: A Discussion of Retrieval of Chronically Implanted Dual-Chamber Leadless Pacemakers in an Ovine Model

Discussion Topic: Retrieval of Chronically Implanted Dual-Chamber Leadless Pacemakers in an Ovine Model

Deepthy Varghese, MSN, ACNP, FNP, of Northside Hospital, is joined by Dr. Mikhael F. El-Chami, MD, FHRS of Emory University, School of Medicine, and Dr. Rohit Mehta, MD, FHRS, with Advocate Health to discuss the study evaluated the preclinical performance and safety of retrieving chronically implanted dual-chamber leadless pacemakers (LPs). A total of 18 LPs were implanted in 9 ovine subjects, and after approximately 2 years, all LPs were successfully retrieved using a dedicated transvenous retrieval catheter. The retrieval procedure duration ranged from 2.5 to 36.4 minutes. Postretrieval analysis showed minimal tissue disruption at implant sites, and no significant device-related complications or injuries were observed. The study concludes that the retrieval of helix-fixation dual-chamber LP systems was safe and effective, paving the way for future clinical studies on LP retrieval.
