Key result
Remote magnetic navigation-guided epicardial ablation achieves 100% arrhythmia freedom at 3 months in preliminary cases.
Why the study?
Percutaneous epicardial mapping and ablation is an emerging treatment for VT, PVC, and accessory pathways, and the feasibility and safety of remote magnetic navigation for this approach needed evaluation.

Should not yet change practice; hypothesis-generating for remote magnetic navigation in epicardial ablation.
Percutaneous epicardial mapping and ablation is an emerging method to treat ventricular tachycardias (VT), premature ventricular complexes (PVC), and accessory pathways. The use of a remote magnetic navigation system (MNS) could enhance precision and maintain safety. This multiple case history demonstrates the feasibility and safety of the MNS-guided epicardial approach in mapping and ablation of ischaemic VT, outflow tract PVCs, and a left-sided accessory pathway. All patients had previously undergone endocardial mapping for the same arrhythmia. MNS could present an advantage from more precise navigation for mapping and maintaining catheter stability during energy application.

Ábrahám et al. (2013) conducted a case report in Ventricular arrhythmias and accessory pathways (n=3). Remote magnetic navigation system (MNS) guided epicardial ablation was evaluated on Feasibility and safety (successful ablation and freedom from arrhythmias at follow-up). Remote magnetic navigation-guided epicardial ablation was feasible and safe, achieving successful ablation and freedom from arrhythmias at 3 months in all three patients.
