Non-Invasive Programmed Stimulation (NIPS) to Guide the Subsequent VT Therapeutic Strategies

NCT06669299 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 51

No results posted yet for this study

Summary

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.

Conditions

  • Ventricular Tachycardia (VT)

Interventions

PROCEDURE

Re-Do ventricular tachycardia ablation

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.

DRUG

Antiarrhythmic Drug Therapy (amiodarone, sotalol, or mexiletine)

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.
