Heart Failure, Atrial Fibrillation, and Catheter Ablation

For each of the secondary endpoints, a catheter ablation strategy repeatedly showed a more markedly positive response from baseline than a rate control strategy although not always reaching statistical significance. [...]the investigators can reasonably conclude that rhythm control by catheter ablation in their laboratory is more effective than good rate control in the studied population of patients with medically optimized HF. [...]only 14 of 26 (54%) of the ablation arm and 15 of 26 (58%) of the rate control arm had undergone a previous cardioversion.
