Aims Force–Time Integral (FTI) is commonly used as a marker of ablation lesion quality
during pulmonary vein isolation (PVI), but does not incorporate power. Ablation Index (AI) is …

Background—Pulmonary vein reconnection (PVR) still determines recurrences of atrial
fibrillation after contact force (CF)–guided pulmonary vein isolation. We studied whether …

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 …

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

Background—Pulmonary vein isolation is the most prevalent approach for catheter ablation
of paroxysmal atrial fibrillation. Long-term success of the procedure is diminished by …

Aims A challenge of pulmonary vein isolation (PVI) in catheter ablation for paroxysmal atrial
fibrillation (PAF) is electrical reconnection of the PV. EFFICAS I showed correlation between …

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

Aims Radiofrequency ablation creates irreversible cardiac damage through resistive heating
and this temperature change results in a generator impedance drop. Evaluation of a novel …

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 …

Background Atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI) is
associated with PV to left atrium reconduction. Effective lesion creation necessitates …
