Primary outcomePrimary: Percentage of Subjects Who Are Inappropriate Shock Free — 98.5; 97.5 percentage of patients
Summary
The purpose of the study is two-fold. In Phase I (Protecta Clinical Study), system performance will be evaluated. In Phase II (PainFree SST), the inappropriate shock-free rate at one year of subjects implanted with a Medtronic Protecta implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) will be evaluated.

Eligibility Criteria
Inclusion Criteria
- Patients meeting one of the following criteria can be included in Phase I of the study:
- Patients indicated (per local indications) for a dual chamber implantable cardioverter defibrillator (DR-ICD)/cardiac resynchronization therapy defibrillator (CRT-D)
- Patients undergoing a device replacement or upgrade to DR-ICD or CRT-D and with the protocol required leads (patients must be enrolled prior to implant)
- Patients meeting one of the following criteria can be included in Phase II of the study:
- Patients indicated for a DR-ICD/VR-ICD/CRT-D device and intended to receive a Protecta device
- Patients undergoing a DR-ICD/VR-ICD/CRT-D device replacement or an upgrade to a Protecta DR-ICD/VR-ICD or CRT-D
- Patients indicated for a DR-ICD/VR-ICD/CRT-D already implanted with a Protecta device and the protocol required leads, who have not yet been discharged after implant
Exclusion Criteria
- Patients with a mechanical tricuspid heart valve
- Patients enrolled or intended to participate in any concurrent drug and/or device study, which would confound the results of this trial as determined by Medtronic, during the course of this clinical study
- Patients with medical conditions that preclude the testing required for all patients by the study protocol or that otherwise limit study participation required for all patients
- Patients with exclusion criteria required by local law (e.g. age, pregnancy, breast feeding, etc)
- Patients anticipated not being able to complete the study
- Patients unwilling to provide written informed consent
