About
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.
Full description
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.

Inclusion and exclusion criteria
LEADR Inclusion Criteria:
Subject meets current clinical practice guidelines for implantation of ICD or CRT-D and will undergo one of the following:
Subject has, per local law and requirements, the minimum age for autonomously signing an ICF (minimum age of 18 years)
Subject is willing to undergo implant defibrillation testing if requested.
Subject is geographically stable and willing and able to complete the study procedures and visits for the duration of the follow-up.
LEADR Exclusion Criteria:
Subject is unwilling or unable to personally provide Informed Consent.
Subject has contraindications for standard RV transvenous lead placement (e.g., mechanical right heart valve).
Subject is contraindicated for ≤1 mg dexamethasone acetate.
Subject has a life expectancy of less than 12 months
For subject undergoing defibrillation testing the following medical conditions exclude them:
Subject is enrolled or planning to enroll in a concurrent clinical study that may confound the results of this study, without documented pre-approval from a Medtronic study manager.
Subject with any exclusion criteria as required by local law (e.g., age or other).
Pregnant women or breastfeeding women, or women of childbearing potential and who are not on a reliable form of birth regulation method or abstinence
Subject with an existing pacemaker (including transcatheter pacing system), ICD, or CRT device or leads
Subject with any evidence of active infection or undergoing treatment for an infection
Recent (or planned) cardiac surgery or stenting less than 1 month before implant
End stage renal disease

LEADR LBBAP Inclusion Criteria:
Subject meets current local clinical practice guidelines for implantation of ICD (single or dual chamber) or CRT-D system and will undergo one of the following:

Subject is 12 years of age or older and also is greater than 30 kg in weight at time of enrollment, has cardiac anatomy conducive to RV coil placement, and is allowed to participate in study per local law and requirements. Subjects from 12 years of age until adult also have a separate indication for pacing or CRT or are anticipated to develop one.

Subject has a life expectancy of less than 12 months
For subject undergoing defibrillation testing the following medical conditions exclude them:
Subject is enrolled or planning to enroll in a concurrent clinical study that may confound the results of this study, without documented pre-approval from a Medtronic study manager

Subject with any evidence of active bacterial infection or undergoing treatment for a bacterial infection within the last 30 days
