Key result
The rate of catheter ablation for hospitalized patients with atrial fibrillation increased significantly from 0.06% in 1990 to 0.79% in 2005, representing a 15% annual increase (95% CI 13-16%).
Observational (n=269,471)
Yes
Effect estimate: 15% increase per year (95% CI 13-16)
Absolute Event Rate: 0.79% vs 0.06%
p-value: p=<0.001
The use of catheter ablation for atrial fibrillation in the United States increased significantly between 1990 and 2005, with ablated patients generally being younger and having fewer comorbidities.

Rising ablation rates in hospitalized AF signal evolving practice; leaves open optimal patient selection and outcome impact.
Kneeland et al. (2009) conducted an observational in Atrial fibrillation (n=269,471). Catheter ablation vs. No ablation was evaluated on Rate of catheter ablation over time (15% increase per year, 95% CI 13-16, p=<0.001). The rate of catheter ablation for hospitalized patients with atrial fibrillation increased significantly from 0.06% in 1990 to 0.79% in 2005, representing a 15% annual increase (95% CI 13-16%).
