Transcatheter non-acute retrieval of the tine-based leadless ventricular pacemaker
Authors' conclusion
A series of transvenous late retrievals of implanted TPS devices demonstrated safety and feasibility, followed by elective replacement with a new leadless pacing device or conventional transvenous pacing system.
