The CHANNELED-Registry is a multicenter retrospective study to (1) systematically assess the mechanism and origin of ventricular tachycardia in patients with end-stage heart failure carrying an left ventricular assist device (LVAD) and (2) to evaluate procedural parameters and outcome of ventricular tachycardia ablation in this special subset of patients.

Assessment of VT recurrence after ablation: Device interrogation and readout of ICD Holter
Time frame: 12 month
Mortality (physiological parameter)
Assessment of mortality after VT ablation.
Time frame: 12 month
Heart failure Hospitalization (physiological parameter)
Assessment of Hospitalization for worsening of Heart Failure after VT ablation.
Time frame: 12 month
