Key result
Atrioventricular junction ablation significantly increased biventricular pacing (mean difference 8.80 percentage points; 95% CI 5.99-11.61) compared to no ablation or rate control.

Mean Difference: 8.8 (95% CI 5.99–11.61)
AVJA significantly improves biventricular pacing in CRT recipients with atrial fibrillation, but contemporary evidence does not show statistically significant improvements in mortality or heart failure hospitalizations.
Abomohsen et al. (2026) conducted a meta-analysis in Atrial fibrillation in cardiac resynchronization therapy (CRT) recipients (n=16). Atrioventricular junction ablation (AVJA) vs. No AVJA or pharmacological rate control was evaluated on Biventricular pacing (MD 8.80, 95% CI 5.99-11.61). Atrioventricular junction ablation significantly increased biventricular pacing (mean difference 8.80 percentage points; 95% CI 5.99-11.61) compared to no ablation or rate control.
