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.
Registry-reported information. Elapsed time and enrollment totals alone do not measure study progress or recruitment pace.
