Catheters, Cardiac, Ablation, Radiofrequency
Definition : Cardiac ablation catheters that use radio-frequency (e.g., 482 or 500 kHz) energy to destroy target endocardial tissue. These catheters typically consist of a 7 Fr multipolar (e.g., quadripolar) catheter with a distal electrode length of 2 to 4 mm. A neutral electrode is placed on the body surface. Some of these catheters are operated in power control mode, while other electrodes include a thermocouple in their tip for temperature controlled mode capability. Radio-frequency ablation catheters are mostly used for treatment of atrioventricular nodal reentrant tachycardia, accessory pathways, and atrioventricular junction ablation.
