Septal - Success Rate and Clinical Outcome of Septal Implant of Ventricular Defibrillation Lead
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 |

|
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.
Study Design

Outcome Measures
Primary Outcome Measures
- 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
- - 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]
- 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
- Spontaneous Episodes and Therapy Delivery - at Least One Appropriate Treatment [Discharge, 3 Months, 6 Months, 12 Months, 36 Months, 60 Months]
- Spontaneous Episodes and Therapy Delivery - at Least One Inappropriate Treatment [Discharge, 3 Months, 6 Months, 12 Months, 36 Months, 60 Months]
- Evolution of Left Ventricular Ejection Fraction [12 Months]
LVEF at 12 months and the change in LVEF at 12 months compared to implant (in %)
