In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based
safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007 …

Background Pulmonary vein isolation (PVI) using high power delivered by SmartTouch
Surround Flow (STSF) catheters guided by ablation index (AI) was evaluated in a …

Typical atrial flutter (AFL), defined as cavotricuspid isthmus (CTI)‐dependent macro‐re‐
entrant atrial tachycardia, often causes debilitating symptoms, and is associated with …

Purpose Reconnection of pulmonary veins (PVs) remains common following radiofrequency
catheter ablation for atrial fibrillation (AF). Ablation Index (AI) is a novel ablation quality …

Aims While the CLOSE protocol proposes a maximally tolerable interlesion distance (ILD) of
6 mm for ablation index ablation index-guided atrial fibrillation (AF) ablation, a target ILD has …

Background The combination of contact force (CF) and local impedance (LI) may improve
tissue characterization and lesion prediction during radiofrequency (RF) ablation. Objective …

Aims Pulmonary vein isolation (PVI) using ablation index (AI) incorporates stability, contact
force (CF), time, and power. The CLOSE protocol combines AI and≤ 6 mm interlesion …

Purpose To determine the efficacy and identify the relevant factors for durable lesion
creation in pulmonary vein isolation (PVI) using a high-power short-duration (HPSD) …

Background The effectiveness of radiofrequency catheter ablation (RFCA) in atrial
tachyarrhythmias correlates with lesion transmurality. Ablation Index (AI) is an index that …

Background: Key determinants for lesion formation in catheter ablation are contact force,
radiofrequency (RF) power and time. The aim of this study was to evaluate the clinical …
