Leadevaluatie voor defibrillatie en betrouwbaarheid (LEADR)

13 oktober 2026 bijgewerkt door: Medtronic Cardiac Rhythm and Heart Failure

The LEADR study is designed to assess the safety and efficacy of the Next Generation ICD lead.

The LEADR LBBAP study is being conducted under the existing US FDA Investigational Device Exemption (IDE) for the Next Generation ICD Lead and is designed to confirm the safety and defibrillation efficacy of the Next Generation ICD Lead when placed in the LBBAP location in ICD and LOT-CRT patient population.

Studie Overzicht

Gedetailleerde beschrijving

The LEADR and LEADR LBBAP studies will enroll subjects who are indicated to receive an implantable single or dual chamber ICD, or CRT-D, and who meet all of the inclusion criteria and none of the exclusion criteria. Subjects will receive an investigational Next Generation ICD Lead. Subjects in the LEADR study will be followed for at least 18 months following Next Generation ICD Lead implantation in a septal (non-LBBAP) or apical implant location. Enrollment in the LEADR study has been completed (675 subjects enrolled). Subjects in the LEADR LBBAP study will be followed for at least 3 months (ICD-indicated subjects) or 6 months (CRT-indicated subjects) following Next Generation ICD Lead implantation in an LBBAP implant location. Enrollment in the LEADR LBBAP study has been completed (332 subjects enrolled).
