NCT01401608

Brief Summary

This study will assess the outcomes of using magnetic navigation to treat ventricular tachycardia (VT) or premature ventricular contractions (PVCs) that occur for unknown reasons and are not related to structural heart disease.

Outcome Measures

Primary Outcomes (1)

  • Change in 24-hour Holter Monitor (number of extra ventricular beats)

    Use of the MNS in mapping and ablation of idiopathic VT will lead to a 75% reduction in the number of individual ventricular ectopic beats 6 months after the procedure. Extra ventricular beats will be counted using a 24-hour Holter monitor pre-procedure (obtained no more than 30 days prior to the procedure) compared to a 24-hour Holter monitor 6 months post-procedure.

    Change from Holter Monitor Pre-procedure vs. 6-Months Post-procedure

Study Arms (1)

Treatment

Ablation of VT/PVCs using a magnetic RF ablation catheter

Device: RF Ablation

Interventions

Ablation of arrhythmogenic ventricular tissue

Also known as: ThermoCool, Niobe, Stereotaxis

Study Population

Patients will be diagnosed with any ventricular tachycardia or symptomatic PVCs of non-ischemic origin.

You may qualify if:

  • Patients must be between 18 - 80 years of age
  • Willing to provide written informed consent
  • Present with ventricular ectopy of non-ischemic origin
  • able to be safely exposed to a static magnetic field
  • Failure of at least 1 antiarrhythmic medication

You may not qualify if:

  • Presence of a mobile ventricular thrombus
  • Unable to obtain percutaneous access to the left ventricle
  • Contraindicated for short-term anticoagulation therapy
  • Life expectancy less than 1 year
  • Body habitus limits placement on the procedure table
  • Previously failed ablation procedure for VT/PVCs
