Experimental study on the effectiveness and safety of radiofrequency catheter ablation with the cooled ablation system.
Experimental in vitro and in vivo studies were performed to assess the effectiveness and safety of the cooled-tip catheter and the Cooled Ablation System, which enables the creation of deeper and wider burn lesions in the myocardial tissue using radiofrequency current. This system was confirmed to consistently create large burns by cooling the catheter tip with circulating water within the cath...
متن کاملRadiofrequency Catheter Ablation and Antiarrhythmic Drug Therapy
Background—Information on comparative outcome between radiofrequency catheter ablation (RFA) and antiarrhythmic drugs (AADs) 1 year after randomization is important for clinical decision-making. Methods and Results—A total of 198 patients (age, 56 10 years) with paroxysmal atrial fibrillation were randomly assigned to RFA (99 patients) or to AADs (99 patients). We evaluated efficacy of RFA or A...
متن کاملEndocardial and Epicardial Radiofrequency Catheter Ablation
Myocarditis is simply defined as an inflammatory condition mainly located in the heart muscle, although considerable uncertainties still persist as to its etiologic, pathological, and clinical subclassifications. In addition to the possibility of an aspecific flulike prodrome, possible presentations include different degrees of heart failure (ranging from cardiogenic shock to subtly progressive...
متن کاملComparing Safety and Efficacy of Irrigated Radiofrequency Catheter Ablation Versus Combined Cryoballoon and Catheter Ablation for Persistent Atrial Fibrillation.
Background: Catheter and cryoballoon ablation are established treatments for atrial fibrillation. Frequently, substrate modification of the left atrium is performed in patients with persistent AF or evidence of left atrial adverse remodeling. We compared one year outcomes of AF ablation with substrate modification utilizing radiofrequency catheter ablation (RFA) compared to a combination of cry...

any importance to thallium data even in these young patients. Nevertheless, it is open to speculation whether this important subgroup is characterized by a special anatomical substrate' or pathophysiological mechanism leading to an extraordinarily high degree of subendocardial ischaemia. Mainly because of methodological problems, ambulatory ST-monitoring seems to be of limited value for ischaem...
