About this trial

The aim of this study is to define the importance of non-invasive programmed stimulation (NIPS) in risk stratification of ventricular tachycardia (VT) recurrence after catheter ablation and to determine the optimal treatment strategy. The primary objective is to establish whether a new VT ablation based on NIPS inducibility will reduce the risk of VT recurrence compared to antiarrhythmic drug therapy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with an implanted ICD (all brands)

Patients who underwent a successful (non-inducibility of any VT) Ventricular Tachycardia Ablation procedure, the "index procedure", supported by EnSite Precision or CARTO 3D mapping systems for the following etiologies: previous MI, myocarditis, ARVD, IDCM.

Induction of monomorphic VT at NIPS 3-7days after a successful index procedure

Age 18 years or more

Disqualifiers

Inducible VT after index procedure

Contraindication to anticoagulants

Presence of thrombi

Presence of Mitral and Aortic prosthetic valve

Trial design

Design model

Parallel

Treatments tested in this trial

  • Re-Do ventricular tachycardia ablation

    Procedure/Surgery

    1\. Programmed ventricular stimulation (PVS); 2. Mapping during Sinus Rhythm (SR) or right ventricular pacing in pacing dependent patients; 3. Late Potentials identification; 4. VT(s) induction with diastolic pathway mapping when possible; 5. Catheter Ablation in SR or, at the operator's discretion, in VT if tolerated by the patient; 6. If VT is not inducible or the diastolic pathway is not mappable, a substrate ablation approach will be performed. 7. PVS is repeatedly attempting to reinduce VT after completing; 8. Endpoint: non-inducibility of any VT.

  • Antiarrhythmic Drug Therapy (amiodarone, sotalol, or mexiletine)

    Drug

    The patients with a positive NIPS already on antiarrhythmic drugs (AAD) before the index procedure will re-start the original antiarrhythmic therapy. Patients who were not on AAD will start a new drug at the operator's discretion (amiodarone, sotalol, or mexiletine) according to clinical practice.
