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
Inducible VT after index procedure
Contraindication to anticoagulants
Presence of thrombi
Presence of Mitral and Aortic prosthetic valve
