Brief Summary

Catheter ablation of Ventricular Tachycardias is a well-established approach in clinical practice in patients with Implantable Cardioverter Defibrillator (ICD) implanted. Previous studies have shown a significant reduction in appropriate shocks (\~ 20%) and a significant reduction in hospitalizations for cardiovascular reasons (\~ 12%) in patients with ischemic heart disease treated with ablation. Recent works have also shown the effectiveness of the ablation procedure using as procedural target the reduction of late potentials. However, actually it is necessary to have an homogenize and accepted mapping scheme in Sinus Rhythm to ablate Ventricular Tachycardias related to scar substrate in patients with:

  • Previous MI
  • Previous myocarditis
  • Arrhythmogenic Right Ventricular Dysplasia (ARVD)
  • Idiopathic Dilated Cardiomyopathy (IDCM) Scope of the registry is to collect data during cardiac mapping in Sinus Rhythm in patients indicated for Ventricular Tachycardia ablation, that will be performed per clinical practice, by using the St. Jude Medical EnSiteTM PrecisionTM mapping system. The objective of the present registry is: to assess the acute and long-term efficacy of the strategy of substrate abolition (abolishment of complex and late potentials) guided by electroanatomic mapping with Precision software.

Outcome Measures

Primary Outcomes (2)

  • Late potential abolition and ventricular tachycardia noninducibility

    Combined procedural endpoint of late potential (LP) abolition and VT noninducibility (endpoint expected in 50% of cases). LP abolition assessed as % of persistent LP area at remap after ablation, compared to the basal activation map.

    Intraprocedural

  • Ventricular tachycardia recurrence

    Freedom from Ventricular Tachycardia episodes requiring ICD Intervention (shock or Anti-Tachycardia Pacing)

    12 months

Secondary Outcomes (8)

  • Complications

    During hospitalization: starting during the procedure until discharge

  • Complications

    12 months

  • Procedural parameters

    Intraprocedural

  • Procedural parameters

    Intraprocedural

  • Assessment of cardiac mapping system EnSite Precision™ software (St.Jude, now Abbott)

    Intraprocedural

  • +3 more secondary outcomes

Interventions

Ventricular Tachycardia ablation, that will be performed per clinical practice, by using EnSite Precision mapping system with the Flexability catheter (St.Jude, now Abbott)
