Catheter Ablation, VT Ablation in LVAD patients
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Heart failure Hospitalization (physiological parameter) | 12 month | Assessment of Hospitalization for worsening of Heart Failure after VT ablation. |
| Mechanism of ventricular tachycardia in LVAD patients (descriptive name of scale) | 12 month | Assessment of the mechanism of VT in LVAD patients (e.g LVAD cannula related vs. related to substrate of underlying heart disease) |
| Number of patients with ventricular tachycardia recurrence in device interrogation (physiological parameter) | 12 month | Assessment of VT recurrence after ablation: Device interrogation and readout of ICD Holter |
| Mortality (physiological parameter) | 12 month | Assessment of mortality after VT ablation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Procedure duration (From groin puncture to sheath removal in minutes) | 12 month | Evaluation of the duration of VT ablation procedures in LVAD patients |
| Fluoroscopy time (minutes) | 12 month | Evaluation of the fluroscopy use (in minutes) |
| Radiofrequency energy used for ablation (in watts; e.g. 40 Watts) | 12 month | Evaluation of the maximum RF-energy used for ablation |
| Number of patients suffering from intraprocedural complication (physiological parameter, e.g. hematoma) | 12 month | Evaluation of intraprocedural complications of VT ablation |
