Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to collect data on laser ballon (2nd gen) systems for catheter ablation for AF, in order to determine the safety and the efficacy of this technique.

Moreover, the investigators aim to determine the short and long term outcomes of pulmonary vein isolation evaluating arrhythmia recurrence, especially using continuous rhythm monitoring with implantable loop recorders (ILR).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

LIGHT-AF is an observational, multicentric study designed to collect pre-procedural, procedural and follow-up data of consecutive patients that underwent catheter ablation for AF with laser ballon (2nd gen system). A number of 3 enrolling centers is estimated with an overall number of about 100 patients. A minimal follow-up of 3 months is required before analyzing clinical outcomes. The data analysis will focus on implant outcomes and early, mid and long-term recurrence of AF, evaluated with intracardiac rhythm monitoring.

Catheter Ablation for AF

Pulmonary vein isolation (PVI) is the mainstay goal of atrial fibrillation (AF) ablation procedures, especially in paroxysmal AF (PAF), and is recommended during all AF ablation procedures. PVI can be obtained with different techniques, using 3D-mapping systems guiding point-by-point radiofrequency (RF) ablation procedures or balloon-based ablation systems (cryo- or laser balloon), introduced to simplify catheter ablation for AF. In particular, the 2nd generation of visually guided laser balloon ablation system (LB2) makes use of laser energy to achieve PVI, leading to better PV occlusion and isolation compared to the 1st generation.
