Leadless pacemaker placement in a pediatric tetralogy of Fallot patient with previous transcatheter valve replacement

Novel use of an atrial sensing leadless pacemaker to treat complete heart block in a patient with repaired tetralogy of Fallot with pre-existing dual-chamber pacemaker with ventricular lead fracture

“…Another unique aspect of this case was placement of the leadless pacemaker in an adult with a repaired tetralogy of Fallot. There are 2 case reports of leadless pacemakers in pediatric patients, 4,5 but there have been no large case series in adults with congenital heart disease. Given the ventricular septal defect repair, the pulmonic valve replacement, and the right ventricular outflow tract revision, the deployment of the leadless pacemaker was challenging in our patient, and the right ventricular angiogram aided in procedural planning.…”
