Study Details

Study Description

Brief Summary

The purpose of this study is to determine the safety and efficacy of the implant of a ICD lead of defibrillation in the septum of the right ventricle

Condition or Disease Intervention/Treatment Phase
  • Device: Endotak Reliance G
N/A

Detailed Description

The rate of success at implant and the positive clinical outcomes for the patients implanted with a lead of defibrillation at the septal site would make it possible to recommend this site as a "new standard" for implant of the defibrillation lead in the RV for ICD.

Outcome Measures

Primary Outcome Measures

  1. Implant Success Rate at Septal Site [At implant]

    Success of implant procedure: 1. implanted at the randomized site; 2. With electric criteria satisfied: pacing threshold < 1.5V, intrinsic amplitude >3 mV, impedance between 450 and 1800 Ω, shock impedance between 29 and 80 Ω and defibrillation at a maximum of 21J.

Secondary Outcome Measures

  1. - The Number of "Low Energy" Shocks (at 11 Joules), Efficient in the VT Zone, in the Population Programmed at This Recommended Value. [3 months, 6 months, 12 months, 36 months, 60 months]

  2. The Rate of ATP Success Therapy [3 months, 6 months, 12 months, 36 months, 60 months]

    in VT zone with at least one efficient ATP

  3. Spontaneous Episodes and Therapy Delivery - at Least One Appropriate Treatment [Discharge, 3 Months, 6 Months, 12 Months, 36 Months, 60 Months]

  4. Spontaneous Episodes and Therapy Delivery - at Least One Inappropriate Treatment [Discharge, 3 Months, 6 Months, 12 Months, 36 Months, 60 Months]

  5. Evolution of Left Ventricular Ejection Fraction [12 Months]

    LVEF at 12 months and the change in LVEF at 12 months compared to implant (in %)
