Comparison of a Novel Temperature-Controlled Diamond-Tip Catheter and a Power-Controlled Gold-Tip Catheter for the Irrigated Ablation of Cavotricuspid Isthmus-Dependent Atrial Flutter.

ABSTRACT: Background/Objectives: Radiofrequency (RF) ablation of the cavotricuspid isthmus (CTI) is a recommended treatment option for typical atrial flutter (AFL). While power-controlled ablation has been the current standard, a novel temperature-controlled ablation system has been introduced. We aimed to compare the procedural efficacy and one-year outcome of a temperature-controlled diamond-tip catheter with an established power-controlled gold-tip catheter. Methods: Consecutive patients undergoing ablation of CTI-dependent AFL using a power-controlled catheter or the novel temperature-controlled catheter were enrolled. Patients were followed up using a 7-day electrocardiogram after 3, 6, and 12 months. The primary endpoint was acute efficacy (procedural success, total RF, and proce
