Key result
Elevated left atrial pressure in sinus rhythm after cardioversion was associated with a higher rate of AF recurrence after catheter ablation compared to non-elevated pressure (48% vs 25%, P=0.0306).
Why the study?
Does elevated left atrial pressure in sinus rhythm relative to atrial fibrillation predict recurrence of AF after catheter ablation?
Population
110 patients who underwent catheter ablation for atrial fibrillation.
Comparison
Elevated LAPSR-AF vs Non-elevated LAPSR-AF (<0 mmHg)
Design
Cohort
Follow-up
13 ± 5 months

May support post-cardioversion LAP for ablation risk stratification; leaves open prospective validation before clinical use.

Absolute Event Rate: 48% vs 25%
p-value: p=0.0306
Elevated left atrial pressure in sinus rhythm relative to atrial fibrillation after cardioversion is an independent predictor of AF recurrence following catheter ablation.
Kishima et al. (2016) conducted an observational in Atrial fibrillation (n=110). Elevated LAPSR-AF (≥0 mmHg) vs. Non-elevated LAPSR-AF (<0 mmHg) was evaluated on Recurrence of AF after catheter ablation (p=0.0306). Elevated left atrial pressure in sinus rhythm after cardioversion was associated with a higher rate of AF recurrence after catheter ablation compared to non-elevated pressure (48% vs 25%, P=0.0306).
