Summary

Atrioventricular junction ablation and pacemaker implantation effectively treats drug-resistant atrial fibrillation (AF). This established therapy improves quality of life, with minimal long-term adverse effects and low thromboembolic risk.

Area of Science:

  • Cardiology
  • Electrophysiology

Background:

  • Atrial fibrillation (AF) is a common arrhythmia.
  • Drug-resistant AF requires alternative treatments.
  • Atrioventricular (AV) junction ablation with pacemaker implantation is a primary non-pharmacologic option.

Purpose of the Study:

  • To evaluate the efficacy and safety of AV junction ablation and pacing for managing atrial fibrillation.
  • To assess the long-term outcomes of this treatment modality.

Main Methods:

  • AV junction ablation using a sequential right- and left-side approach.
  • Pacemaker implantation with appropriate pacing modes (DDDR with mode switching or VVIR).

Main Results:

  • High efficacy (>95%) in achieving complete AV block.
  • Low rate (<5%) of AV block regression.
  • Established clinical efficacy in paroxysmal AF; less data for persistent/permanent AF.
  • No evidence of increased thromboembolic risk or adverse long-term cardiac effects in controlled trials.

Conclusions:

  • Ablate and pace therapy is a safe and effective treatment for drug-resistant atrial fibrillation, particularly paroxysmal AF.
  • Further studies are needed for persistent and permanent AF.
  • The procedure offers significant quality of life improvements for eligible patients.
