Abstract

Monomorphic ventricular tachycardia (VT) and symptomatic monomorphic PVCs originating from the region of the right mid left outflow tracts are increasingly treated by radiofrequency (RF) catheter ablation. Technical difficulties in catheter manipulation to access these outflow tract areas, very accurate mapping and reliable catheter stability are key issues for a successful treatment in this vulnerable region. VT ablation from the aortic sinus cusp (ASC) in particular carries a significant risk of perforation, of creating left coronary artery injury mid of damage to the aorta and the aortic valve. This case series describes RF ablation of VT originating in the outflow region using the remote magnetic navigation system (MNS). Potential advantages of the MNS are catheter flexibility, steering accuracy and reproducibility to navigate to a desired location with a low probability of perforating the myocardium. This report supports the idea of using advanced MNS technology during P,F ablation in regions which are difficult to reach and thin walled, such as parts of the outflow tract and the ASC.
