Trial Comparing Ablation With Medical Therapy in Patients With Ventricular Tachycardia
Ablation Versus Medical Therapy in Patients With Coronary Artery Disease and Sustained Ventricular Tachycardia Randomized Trial (VeTAMed)
This study aims to compare antiarrhythmic drug therapy with catheter ablation using the SmartTOUCH catheter (Biosense Webster Inc.) as treatment for patients with ventricular tachycardia and coronary artery disease
This is a multicenter, randomized prospective cohort study to compare the impact of catheter ablation with antiarrhythmic drug therapy for treating patients with sustained ventricular tachycardia (VT) and coronary artery disease. Patients that meet all inclusion criteria and no exclusion criteria will be recruited to the study cohort. After baseline measurements are taken, patients will be randomized in a 2:1 fashion to either undergo radiofrequency catheter ablation or receive antiarrhythmic drug therapy (amiodarone or sotalol). The in-clinic appointments include: enrollment, baseline, intervention, and follow-up every three months for one year post-ablation. At each follow-up visit, electrogram (ECG) and Holter monitoring tests will be performed to measure any episodes of ventricular tachyarrhythmia. Furthermore, interrogation of the patient's implantable cardioverter defibrillator (ICD) will be performed at all follow-up visits to detect any episodes of ventricular tachyarrhythmia that required antitachycardia pacing (ATP) or shocks.
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Ventricular Tachycardia
  • Coronary Artery Disease
  • Procedure: Catheter Ablation
    Catheter ablation of ventricular tachycardia will employ three-dimensional mapping Fast Anatomical Mapping or CARTOSOUND technology (Biosense Webster Inc.), and the Thermocool Navistar catheter (Biosense Webster Inc.).
    Other Names:
    • Ablation of:
    • - Ischemic ventricular tachycardia
    • - Sustained monomorphic ventricular tachycardia
    • - Clinical ventricular tachycardia
    • - Hemodynamically stable/unstable ventricular tachycardia
  • Drug: Medical therapy (sotalol or amiodarone)
    Patients will be tiered to one of two possible antiarrhythmic drugs (sotalol or amiodarone).
    Other Name: Sotalol - Betapace, Betapace AF, Sotalex, Sotacor
  • Active Comparator: Catheter Ablation
    Radiofrequency ablation procedure
    Intervention: Procedure: Catheter Ablation
  • Active Comparator: Medical therapy
    Antiarrhythmic drug therapy will include amiodarone or sotalol. Which antiarrhythmic drug will prescribed per patient depends on the observing physician.
    Intervention: Drug: Medical therapy (sotalol or amiodarone)
