MedPage Today -- Circular ablation catheters speed up procedures to eliminate paroxysmal atrial fibrillation, researchers affirmed. Cryoablation balloon and circular radiofrequency catheters together cut the total time in the catheterization lab by 91 minutes compared with standard point-by-point radiofrequency catheters (261 versus 170 minutes, P<0.001) in the FAST-PVI study.
