Temperature response in radiofrequency catheter ablation.
T he ablative effect of radiofrequency (RF) energy is based on resistive heating of tissue adjacent to the delivery electrode. Generally, the amount of heat generated relates to the amount of power delivered. Thus, under controlled experimental conditions, delivered power can be used as a parameter to control the amount of myocardial damage.1,2 However, in the clinical situation, a large propor...
متن کاملTemperature monitoring during radiofrequency catheter ablation of accessory pathways.
BACKGROUND Animal studies have suggested that the temperature of the electrode-tissue interface during radiofrequency catheter ablation accurately predicts lesion size. The purpose of the current study was to evaluate the utility of continuous temperature monitoring during radiofrequency catheter ablation in patients with Wolff-Parkinson-White syndrome. METHODS AND RESULTS Twenty patients wit...
متن کاملTemperature-controlled radiofrequency catheter ablation of manifest accessory pathways.
OBJECTIVES The primary objectives of this study were to assess the feasibility of temperature-controlled radiofrequency catheter ablation of left and right sided manifest accessory pathways in patients with Wolff-Parkinson-White syndrome and to gain more insights into biophysical aspects of temperature-controlled catheter ablation in humans. BACKGROUND The electrode-tissue interface temperatu...
متن کاملTemperature-Guided Radiofrequency Catheter Ablation of Accessory Pathway
OBJECTIVES This study was performed to evaluate the usefulness of temperature-guided radiofrequency catheter ablation for the elimination of accessory pathway conduction in patients with Wolff-Parkinson-White syndrome. METHODS Temperature-guided radiofrequency catheter ablation was attempted in 138 patients with 144 accessory pathways (88 pathways along the left free wall, 5 in the anterosept...
متن کاملTemperature-guided radiofrequency catheter ablation with very large distal electrodes.
BACKGROUND Previous studies have shown that the size of lesions produced by radiofrequency catheter ablation correlates with the temperature and surface area of the electrode-tissue interface. The purpose of the present study was to compare the effects of ablation using very large distal electrodes (8F, 8 and 12 mm long) with those made by a conventional radiofrequency ablation catheter (distal...
