- Abstract
Radiofrequency ablation (RFA) of cavotricuspid isthmus (CTI)-dependent atrial flutter can be performed using various types of ablation catheters. Recent evaluations comparing externally cooled-tip RFA (ecRFA) catheters and large-tip (8 mm) catheters found that ecRFA catheter may have a higher efficacy for CTI ablation. The aim of this prospective study was to compare both catheters by stratifying on CTI morphology in order to explain, in part, the discrepancies between previous randomized studies, and to validate predictive factors of difficult CTI ablation on clinical, echocardiographic, and angiographic data.
