Introduction:
Lead extraction and reimplantation in adult congenital heart disease (CHD) patients is challenging due to anatomical complexity.
Case:
A 76-year-old man with prior ventricular septal defect (VSD) patch repair and pacemaker implantation developed a device infection. Complete transvenous lead extraction (TLE) was achieved using laser and mechanical sheaths. A leadless pacemaker (Aveir VR) was implanted at the right ventricular outflow tract (RVOT) using pre-fixation mapping to avoid the VSD patch.
Conclusion:
This case illustrates the effectiveness of pre-mapping in achieving safe reimplantation of a leadless pacemaker after TLE in complex CHD anatomy.
