- •Prior abdominal surgery in the epigastric region
- •Planned sternotomy
- •Prior chest radiotherapy
- •Or any other prior/planned medical intervention not listed that precludes their participation in the opinion of the Investigator.
- •Patient has previous pericarditis that:
- •Was chronic and recurrent, or
- •Resulted in pericardial effusion [v], or
- •Resulted in pericardial thickening or calcification [vi].
- •Patients with these medical conditions or anatomies are excluded from participation in the study:
- •Hiatal hernia that distorts mediastinal anatomy
- •Marked sternal abnormality (e.g., pectus excavatum)
- •Decompensated heart failure
- •COPD with oxygen dependence
- •Gross hepatosplenomegaly Or any other known medical condition or anatomy type not listed that precludes their participation in the opinion of the Investigator.

- •Recent stroke or transient ischemic attack (within the last 6 months)
- •Known inadequate external defibrillation
- •LVEF <20%
- •LVEDD >70 mm Or any other known medical condition not listed that precludes their participation in the opinion of the Investigator.
- •Patient with any evidence of active infection or undergoing treatment for an infection.
- •Patient is contraindicated from temporary suspension of oral/systemic anticoagulation
- •Patient with current implantation of neurostimulator or any other chronically implanted device that delivers current in the body.
- •Patient meets ACC/AHA/HRS or ESC clinical guideline Class III criteria for an ICD (e.g., life expectancy of less than 12 months).
- •Patient 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.
- •Patient with any exclusion criteria as required by local law (e.g., age or other).
- •Pregnant women or breastfeeding women, or women of child bearing potential and who are not on a reliable form of birth regulation method or abstinence.

Outcomes
Primary Outcomes
Safety Outcome - Freedom From Major Complications Related to the EV ICD System and/or Procedure at 2 Weeks Post-implant
Time Frame: 2 weeks (14 days) post-implant
The endpoint is defined as a subject's first occurrence of a major complication related to the EV ICD System and/or procedure, as determined by an independent Clinical Events Committee (CEC), that occurs on or prior to 2 weeks (14 days) post-implant.
Efficacy Outcome - Defibrillation Efficacy at Implant of the EV ICD System
Time Frame: At Implant
Each subject will demonstrate a successful defibrillation outcome if either 2 successive induced ventricular fibrillation episodes are terminated by the subject's device delivering a shock at the required energy level, or if one such episode is successfully terminated by the subject's device delivering a shock at a lower energy level. Up to 6 such episodes may be induced to test device efficacy.
Secondary Outcomes
No secondary outcomes reported
