Methods In this prospective study, we enrolled 80 patients with CTI-dependent AFl. The first
40 patients underwent standard fluoroscopy+ ICE-guided ablation (Standard ICE group) …

Randomized Trial of ICE During CTI Ablation. Introduction: Despite a high success rate,
radio‐frequency ablation (RFA) of the cavotricuspid isthmus (CTI) can be unusually …

Aims Ablation index (AI) is a marker of lesion quality during catheter ablation that
incorporates contact force, time, and power in a weighted formula. This index was originally …

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 …

Atrial flutter (AFL) represents a prevalent variant of supraventricular tachycardia,
distinguished by a macro-reentrant pathway encompassing the cavotricuspid isthmus (CTI) …

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

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 …

Cavo-tricuspid isthmus (CTI) anatomies are highly variable, and specific anatomies lead to a
difficult CTI ablation. This study aimed to compare the clinical utility of angiography and …

Ablation index (AI)-guided ablation is useful for pulmonary vein isolation (PVI) and
cavotricuspid isthmus (CTI) ablation. However, the impact of radiofrequency (RF) application …

Background Cavo‐tricuspid isthmus (CTI) linear ablation is performed not only for atrial
flutter (AFL) but empirically during atrial fibrillation (AF) ablation in real‐world practice …
