Open-label multicentre RCT

Desenlace

Composite of death, disabling stroke, serious bleeding, or cardiac arrest

Relevancia

Resultado8.0% vs 9.2% (HR 0.86, 95% CI 0.65-1.15; P=0.30); neutral by intention-to-treat. Per-protocol and as-treated analyses favoured ablation.

Discusión y crítica

Substantial crossover between arms diluted the intention-to-treat comparison. Although the primary endpoint was neutral, ablation improved quality of life and became reasonable first-line rhythm control for symptomatic AF.
