Atrial Fibrillation Ablation Using Magnetic Navigation Comparison With Conventional Approach During Long-Term Follow-Up


Atrial fibrillation (AF) ablation targeting the circumferential isolation of pulmonary veins (PVI) is an established therapeutic alternative in symptomatic AF patients resistant to anti-arrhythmic medications. The procedure technically challenging and multiple difficulties must be overcome in order to achieve a successful outcome. The magnetic navigation system (MNS) is a remote catheter control technology that has an advantages such as an atraumatic catheter design that improves the procedural safety, a reduced amount of radiation exposure to both the patient and physician, unrestricted and reproducible catheter manoeuvrability that allows the access to difficult anatomical situations, and an  improved catheter stability lead to better energy delivery. Due to these advantages, MNS is increasingly being used for AF ablation and both acute and chronic success rates are comparable with the conventional technique. However, MNS is related to longer radiofrequency (RF) application duration  and  procedure time. But, the new developments in navigation systems, catheters and sheaths used, combination of MNS and a new three-dimensional mapping systems are very promising to obviate these concerns.
