Summary

This is an early-stage feasibility study. This study seeks to characterize the performance of the new electrode shock configuration with the S-ICD

Eligibility Criteria

Key Inclusion Criteria

  • Subject is scheduled to receive a de novo S-ICD system implant per labeled indication.
  • Passing S-ICD screening ECG performed per applicable user's manual.
  • Subject is willing and capable of providing informed consent specific to local and national laws.
  • Subject is age 18 or above, or of legal age to give informed consentspecific to local and national law.

Key Exclusion Criteria

  • Subject has an unusual chest anatomy (eg. pectus excavatum and pectus carinatum) that might impede the ability to temporarily insert a second S-ICD electrode.
  • Subject has a left ventricular ejection fraction ≤ 20% within 3 months prior to enrollment.
  • Subject has NYHA Class IV or unstable Class III heart failure.
  • Subject that, in the opinion of the investigator, cannot tolerate the DFT testing required by this protocol.
  • Subject is morbidly obese, defined as BMI ≥ 35.
  • Subject has an active infection or has been treated for infection within the past 30 days.
  • Subject that, in the opinion of the investigator, has an increased risk of infection.
  • Subject is currently requiring/receiving dialysis.
  • Subject has insulin-dependent diabetes.
  • Subject had/has any prior or planned other surgical procedure within ±30 days of enrollment.
  • Subject that, in the opinion of the investigator, has an increased risk for thromboembolic event.
  • Subject that, in the opinion of the investigator, has an increased risk of excessive bleeding.
  • Subject is currently on an active heart transplant list.
