Temperature Controlled Radiofrequency Ablation
Since its introduction in 1987, radiofrequency (RF) ablation has developed to become the treatment of choice for symptoms caused by atrio ventricular (AV) reentrant tachycardia, isthmus related atrial flutter, AV-nodal reentrant tachycardia and to some extent also for certain types of ventricular tachycardias. The introduction of new cardiac activation mapping systems has further contributed to...
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 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 کاملConvective cooling effect on cooled-tip catheter compared to large-tip catheter radiofrequency ablation.
BACKGROUND Both actively cooled-tip and large-tip catheters are currently available clinically to create large endomyocardial lesions during application of radiofrequency (RF) energy. The purpose of this study was to compare the effect of convective cooling at physiologic flow rates on RF lesion size using both actively cooled and large-tip catheters. METHODS Porcine hearts were sectioned int...
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...
