Safety Profiles and Lesion Size of Different Radiofrequency Ablation Technologies: A Comparison of Large Tip, Open and Closed Irrigation Catheters

Abstract

Catheter type, contact conditions, and power settings all play a role in lesion size and in the frequency of complications that occur during an RFA. Cooling the electrode tip, either internally or externally, does not prevent complications from occurring, especially at the higher power control settings. Adding more temperature sensors to the 10 mm seems to reduce the amount of complications that can occur.
