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 …

Introduction The CLOSE protocol combines ablation index (AI) and≤ 6 mm interlesion
distance using standard power settings for the treatment of atrial fibrillation (AF). The …

Background Atrial fibrillation (AF) ablation outcome is still operator dependent. Ablation
Index (AI) is a new lesion quality marker that has been demonstrated to allow acute durable …

Introduction Pulmonary vein (PV) isolation is the cornerstone of catheter ablation in patients
with atrial fibrillation (AF). Surround flow and contact force (CF) measurement capabilities …

Background Ablation index (AI) is a new lesion quality marker that has been demonstrated
to allow a high single‐procedure arrhythmia‐free survival in single‐center studies. This …

Purpose The ablation index (AI) is a recently developed marker for ablation lesion quality
that incorporates contact force (CF), time, and power in a weighted formula. There is a …

Aims The relative efficacy and safety of open irrigated tip catheters compared with
conventional non-irrigated catheters for pulmonary vein isolation (PVI) is unknown. Methods …

Aims Pulmonary vein isolation (PVI) is the mainstay of interventional treatment of
paroxysmal atrial fibrillation (PAF). We report on the feasibility and efficacy of a novel, open …

Background Pulmonary vein (PV) isolation is the cornerstone of catheter ablation in patients
with atrial fibrillation (AF).“Single-shot” ablation devices have been recently engineered …

Purpose Esophageal injury is a potential complication with radiofrequency ablation in the
posterior wall of the left atrium (LA). The “box isolation” method isolates the posterior LA wall …
