Is transcatheter retrieval and reimplantation of a dislodged leadless pacemaker via a tricuspid valve-in-valve prosthesis feasible and safe?
This case demonstrates the first reported successful transcatheter retrieval and same-day reimplantation of a leadless pacemaker through a tricuspid valve-in-valve prosthesis.
BACKGROUND: Transcatheter retrieval of a dislodged leadless pacemaker (LP) from a tricuspid valve-in-valve (ViV) prosthesis has not been previously reported. CASE SUMMARY: A 42-year-old woman with a prior bioprosthetic tricuspid valve, transvenous pacemaker, and subsequent percutaneous ViV implantation presented with ventricular lead dysfunction. A Micra LP was implanted but dislodged within 7 days. The device was retrieved using a sheath-in-sheath system combined with a double-snare technique under fluoroscopic guidance. The first snare engaged the device, and traction induced tine deformation and device mobilization. After retraction into the right atrium, a second snare enabled coaxial alignment for safe retrieval into the introducer sheath. A new LP was immediately reimplanted with stable electrical parameters that remained satisfactory at 1-year follow-up. No prosthetic valve injury or thromboembolic complications occurred. CONCLUSION: This case demonstrates that transcatheter retrieval and same-day reimplantation of LP via a tricuspid ViV prosthesis is feasible and safe.
Wu et al. (Sun,) conducted a case report in Dislodged leadless pacemaker in a patient with a tricuspid valve-in-valve prosthesis (n=1). Transcatheter retrieval using a sheath-in-sheath system and double-snare technique, followed by reimplantation of a new leadless pacemaker was evaluated on Feasibility and safety of retrieval and reimplantation (stable electrical parameters, no prosthetic valve injury or thromboembolic complications). Transcatheter retrieval of a dislodged leadless pacemaker using a double-snare technique via a tricuspid valve-in-valve prosthesis, with same-day reimplantation, was feasible and safe at 1 year.
