The objective of this study is to demonstrate the efficacy of the ENDOTAK® RELIANCE™ defibrillation leads connected to a defibrillator or a cardiac resynchronization defibrillator from implant until 12 months.
Condition or disease
Ventricular TachycardiaVentricular Fibrillation
Device: Endotak Reliance
Baseline and clinical data were collected at inclusion, as were data on procedural characteristics, device implantation-related adverse events and device programming at the time of hospital discharge. Patients were subsequently divided in two groups: patients who underwent VF induction at implantation or before hospital discharge(VF induction group); and patients who did not undergo VF induction (untested group).The patients were followed up at 3—6 months and at12 months after the implantation. VF induction procedures were left to the investigator's discretion, but reasons for not performing a VF induction at implantation were recorded prospectively. ICD programming parameters for tachycardia or bradycardia were also left at the investigator's discretion.
Defibrillation testing (DT) procedures and consequences on clinical outcomes [ Time Frame: at implant ]
to determine the DT procedures used in everyday practice, to compare the characteristics of patients with or without DTand to compare severe adverse events in these two populations during implantation
Defibrillation testing (DT) procedures and consequences on clinical outcomes [ Time Frame: during 1 year follow-up ]
to determine the DT procedures used in everyday practice, to compare the characteristics of patients with or without DTand to compare severe adverse events in these two populations during 1 year follow-up
