Atrial fibrillation: FIRE or ICE? Cryoablation not inferior, not superior.

The primary analysis of FIRE AND ICE demonstrated that cryoablation was noninferior to radiofrequency ablation for the primary efficacy end point of first documented clinical failure. Secondary analysis suggested that cryoablation had advantages over radiofrequency ablation in terms of rehospitalizations and repeat procedures: however, the validity of these results must be questioned.
