Temperature 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 کاملMonitoring esophageal temperature during catheter ablation.
I comment on a paper just appeared on JAFIB, aimed at providing an index quantifying the convenience of monitoring esophageal temperature during catheter ablation. The authors base their calculation on the data from four papers. I point out that the data from the two papers strongly against monitoring should be interpreted differently and I suggest how to retrieve more data for a more reliable ...
متن کاملImpedance monitoring during radiofrequency catheter ablation in humans.
Radiofrequency catheter ablation of accessory pathways and the atrioventricular junction often requires multiple applications of energy. The inability to determine the effects of any given application on the underlying tissue may contribute to this problem. In the present study, impedance was monitored in 20 patients undergoing radiofrequency catheter ablation, and the relationship between an i...
متن کاملTemperature 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 procedures using closed loop control. Atakr Multicenter Investigators Group.
BACKGROUND The purpose of this study was to evaluate electrode temperatures obtained using a radiofrequency ablation system that incorporates closed loop feedback control to achieve preset target electrode temperatures and to determine if closed loop temperature control results in a lower incidence of developing a coagulum. METHODS AND RESULTS Two hundred seventy patients underwent catheter a...
