Protruding interventricular septum impacts on leadless pacemaker implantation success: Conversion from helix-fixed to tine-fixed system: A case report
The leadless pacemaker (LPM) system has widespread use as the first line therapy for bradyarrhythmia.1,2,3 The two types of LPMs: helix-fixed (AVEIR™; Abbott, CA, USA) and tine-fixed (MicraTM, Medtronic, MN, USA) have their specific advantage and disadvantage. The helix-fixed LPM is superior to tine-fixed LPM in terms of the battery longevity, pretest before screw-in fixation, retrievability, and the dual-chamber (DDD)-LPMs option.4 However, its longer body and delivery catheter curvature might be susceptible to anatomical factors during implantation.
