Pacemaker treatment for bradyarrhythmia was first approved for national health insurance
coverage in Japan in 1974, and its use rapidly became widespread thereafter …

Objectives: This study sought to evaluate the safety and the acute and 1 year outcomes of an
ablation protocol aiming to enclose the PV with a contiguous and optimized RF circle by …

Objectives: This study sought to examine the biophysical properties of high-power and short-
duration (HP-SD) radiofrequency ablation for pulmonary vein isolation. Background …

Aims We have recently shown that a contact force (CF)-guided ablation protocol respecting
region-specific criteria of lesion contiguity and lesion depth ('CLOSE'protocol) is associated …

Aims Pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) in patients with
paroxysmal atrial fibrillation (PAF) is effective but hampered by pulmonary vein reconnection …

Objectives The goal of this study was to compare lesion durability between high-power short-
duration (HP-SD) and moderate-power moderate-duration (MP-MD) ablation strategies …

Aims Late recovery of ablated tissue leading to reconnection of pulmonary veins remains
common following radiofrequency catheter ablation for AF. Ablation Index (AI), a novel …

Introduction PV reconnection is often the result of catheter instability and tissue edema. High‐
power short‐duration (HP‐SD) ablation strategies have been shown to improve atrial linear …
