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 is 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 which has advantages such as a traumatic catheter design improving the procedural safety, a reduced amount of radiation exposure to both the patient and physician, unrestricted and reproducible catheter maneuverability that allows the access to difficult anatomical situations, and an improved catheter stability leading 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. The new developments in navigation systems, catheters and new three-dimensional mapping systems are very promising to obviate these concerns. However, MNS is related to longer radiofrequency (RF) application duration and procedure time.
