Transvenous VDD pacemakers in children are a temporary solution for AV-synchrony. High reoperation rates due to lead tension suggest DDD pacing is better long-term.

Area of Science:

  • Pediatric Cardiology
  • Cardiac Electrophysiology
  • Medical Device Technology

Background:

  • Transvenous AV-synchronous pacing in pediatric patients utilizes VDD leads and miniaturized pacemakers.
  • The long-term efficacy of this therapy in children has been a subject of ongoing investigation.

Purpose of the Study:

  • To retrospectively evaluate the long-term outcomes of transvenous VDD pacing in children.
  • To assess the safety and complication rates associated with VDD pacemaker implantation in pediatric patients.

Main Methods:

  • A retrospective analysis of 104 children under 15 years old who received pacemakers between May 1977 and July 2001.
  • Focus on 55 patients with transvenous leads, specifically the 12 who received VDD pacemakers for hemodynamic reasons.

Main Results:

  • The mean follow-up period was 47.5 months, with VDD pacing functioning 86.3% of the time.
  • Five out of twelve VDD patients (41.7%) required reoperation due to severe lead traction, necessitating explantation and conversion to dual-chamber pacemakers.

Conclusions:

  • Perioperative implantation of VDD pacemakers in children is safe with a low initial complication rate.
  • Significant lead tension requiring reoperation in 41.7% of VDD patients highlights potential long-term challenges.
  • VDD pacing in younger children may serve as a temporary measure, bridging the need for AV-synchrony until conversion to DDD pacing in adulthood is feasible.
