Key result
Positioning an ablation catheter within the left atrial appendage during pulmonary vein pacing successfully identified pseudo-exit conduction in 10.4% of patients undergoing ablation.
Why the study?
Does positioning an ablation catheter in the LAA during PV pacing differentiate pseudo-exit conduction from true PV exit conduction in AF patients undergoing PVI?
Population
135 consecutive patients with atrial fibrillation undergoing pulmonary vein isolation

May differentiate pseudo-exit from true conduction during PVI; leaves open whether this avoids unnecessary ablation.

Does positioning an ablation catheter in the LAA during PV pacing differentiate pseudo-exit conduction from true PV exit conduction in AF patients undergoing PVI?
A simple pacing maneuver using an ablation catheter in the LAA can reliably differentiate pseudo-exit conduction from true PV exit conduction, potentially avoiding unnecessary additional ablation.
Ip et al. (2013) conducted an observational in Atrial fibrillation (n=135). Positioning ablation catheter within the LAA during PV pacing was evaluated on Identification of pseudo-exit conduction. Positioning an ablation catheter within the left atrial appendage during pulmonary vein pacing successfully identified pseudo-exit conduction in 10.4% of patients undergoing ablation.
