The Value of Late Non-Invasive Programmed Stimulation (NIPS) in the Setting of Ventricular Tachycardia (VT) Ablation to Guide the Subsequent VT Therapeutic Strategies: a Prospective Randomized Multicenter Study
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.
• 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
• Able to provide an informed consent to participate to the study and available to respect the assessments described in the protocol.
