Background Clinical utility of large-tip ablation catheters for cavo-tricuspid isthmus (CTI)
ablation has been reported, however, it is limited by the impaired near-field electrogram …

Cavotricuspid isthmus (CTI) ablation is a current first-line management method for typical
atrial flutter. A voltage-directed technique that systematically targets points of maximal …

Objective: Radiofrequency (RF) ablation is a highly successful procedure for the
management of typical atrial flutter (AFL), an abnormal heart rhythm originating within the …

Introduction: Radiofrequency (RF) ablation of the cavotricuspid isthmus (CTI) can be
performed using different types of ablation catheter. Gold tip electrodes have the theoretical …

Background: Gold has excellent electrical conductive properties and creates deeper and
wider lesions than platinum‐iridium during radiofrequency (RF) ablation in vitro. We tested …

Aims The mini electrodes (ME) placed on the tip of the ablation electrode provide more
precise local signal. We evaluated whether ME catheter was effective for the ablation of …

Introduction A new technology capable of monitoring local impedance (LI) and contact force
(CF) has recently been developed. At the same time, there is growing concern regarding …

Background The optimal ablation index (AI) value for cavotricuspid isthmus (CTI) ablation is
unknow. Objective This study investigated the optimal AI value and whether preassessment …

Variable Strategies for CTI Ablation Objectives This study aimed to investigate the
anatomical characteristics complicating cavotricuspid isthmus (CTI) ablation and the …

Background Force‐time integral (FTI) is an ablation marker of lesion quality and
transmurality. A target FTI of 400 gram‐seconds (gs) has been shown to improve durability …
