This is probably a worthwhile read.
"When it comes time to perform AF ablation, many ask the question: Should we freeze or burn? Which technique of pulmonary-vein isolation (PVI) is best?"
"The two most common techniques for PVI are point-to-point RF ablation and cryoballoon ablation. Heat or cold? Fire or ice? Dots or circular lines? At electrophysiology meetings, this is a hot—not cold—topic."
"Here, I think it best to consider this debate from a patient's viewpoint. In other words, if you were the patient, which technique would you choose?"
"One factor you would consider is the experience of the doctor and center. Both techniques of AF ablation require skill, but most electrophysiologists would agree that point-to-point RF ablation demands more time and procedures to master. Compared with the one-shot PV isolation with a cryoballoon, RF ablation involves intricate movements and delivery of many singular lesions to isolate the vein. Where an operator is on this experience curve may be an important factor in comparing the efficacy and safety of the procedure."
