Ventricular Tachycardias Clinical Trial
The purpose of this study is to assess whether the burden of untreated non-sustained ventricular tachycardias (VTs), or episodes treated with anti-tachycardia pacing, correlates with appropriate implantable cardiac defibrillator (ICD) shock therapies and to evaluate if the timing of radiofrequency VT ablation affects the prognosis of ICD recipients.
Enrolled patients will remain in a first phase of the study until the first appropriate ICD
shock will be delivered.
The objective of this first stage is to assess whether the burden of untreated non sustained
VTs or episodes treated with anti-tachycardia pacing is predictive of appropriate ICD shocks.
The second phase of the study will start after the first appropriate ICD shock delivered for
VT.
Patients will be then randomized to immediate VT ablation or to standard treatment, meaning
waiting until next arrhythmic storm to perform a VT ablation procedure.
The objective of this phase is compare the rate of worsening heart failure hospitalizations
and deaths from any cause between the two groups.
