title: Remote magnetic navigation to map and ablate left coronary cusp ventricular tachycardia.
abstract: BACKGROUND
  Premature ventricular contractions (PVCs) and ventricular tachycardia may arise from the coronary cusps. Navigation, mapping, and ablation in the coronary cusps can be challenging. Remote magnetic navigation may offer an alternative to conventional manually operated catheters.
  
  
  OBJECTIVE
  We report a case of left coronary cusp ventricular tachycardia ablation using remote magnetic navigation.
  
  
  METHODS
  Right ventricular outflow tract and coronary cusp mapping, and ablation of the left coronary cusp using a remote magnetic navigation and three-dimensional (3-D) mapping system was performed in a 28-year-old male with frequent, symptomatic PVCs and ventricular tachycardia.
  
  
  RESULTS
  Successful ablation of left coronary cusp ventricular tachycardia was performed using remote magnetic navigation.
  
  
  CONCLUSIONS
  Remote magnetic navigation may be used to map and ablate PVCs and ventricular tachycardia originating from the coronary cusps.
