Overview

May support single-session pacemaker implantation before AV junction ablation in refractory AF; leaves open confirmation across devices in randomized trials.

Structured PICO

Is pacemaker implantation prior to RF ablation of the AV junction in a single session procedure safe and free from pacemaker dysfunction in patients with refractory atrial fibrillation?

P
Population
70 patients with drug-refractory atrial fibrillation undergoing pacemaker implantation prior to RF ablation of the AV junction, followed for an average of 18 months.
E
Exposure
Pacemaker implantation (Thera I and Kappa models with Capsure SP and Z unibipolar leads) prior to RF ablation in a single session procedure, transiently programmed to VVI mode at a rate of 30 beats/min.
O
Outcome
Transient or permanent pacemaker dysfunction (including under/oversensing, reversion to a noise-mode pacing, pacing inhibition, reprogramming, or recycling) and lead parameters (impedance, sensing, and pacing thresholds) in the acute and long-term phase.safety

Implantation of specific pacemaker models prior to RF ablation of the AV junction in a single session is safe and does not result in acute or chronic pacemaker dysfunction.

Cite This Study

Proclemer et al. (2000) conducted an observational in antiarrhythmic drug refractory atrial fibrillation (n=70). Pacemaker implantation prior to RF ablation was evaluated on Transient or permanent pacemaker dysfunction. Pacemaker implantation prior to RF ablation of the AV junction in a single session resulted in 0% transient or permanent pacemaker dysfunction over an average 18-month follow-up.
