Ventricular Arrythmia
Conditions
Brief summary
This study is designed to evaluate the energy requirements of two different Nonvascular ICD (NV-ICD) electrode configurations for achieving successful defibrillation of ventricular arrhythmias.
Interventions
PROCEDURETemporary implantation of defibrillation coils and pulse generator
Each subject will undergo temporary implantation of defibrillation coils and pulse generator according to the NV-ICD electrode configurations.
PROCEDUREDefibrillation following induction of VA (Configuration A first)
Ventricular arrhythmia (VA) will be induced via an EP catheter placed in the right ventricle. After VA is confirmed, a defibrillation shock will be attempted to terminate the arrhythmia. Up to two defibrillation energies will be tested for Configuration A. Then up to two defibrillation energies will be tested for Configuration B.
PROCEDUREDefibrillation following induction of VA (Configuration B first)
Ventricular arrhythmia (VA) will be induced via an EP catheter placed in the right ventricle. After VA is confirmed, a defibrillation shock will be attempted to terminate the arrhythmia. Up to two defibrillation energies will be tested for Configuration B. Then up to two defibrillation energies will be tested for Configuration A.
PROCEDURERemoval of defibrillation coils and pulse generator
Defibrillation coils and pulse generator will be removed from the subject after the defibrillation tests are completed.

Inclusion criteria
1. Patient that is scheduled to undergo surgery requiring midline sternotomy or implantation of a commercially-available TV-ICD or S-ICD system per local guidelines 2. Patient must be at least 18 years of age 3. Subject must provide written informed consent prior to any clinical investigation-related procedure.
Exclusion criteria
1. Pacemaker dependency 2. Chronically implanted cardiac implantable electronic device or other device which delivers an electrical current 3. Currently taking amiodarone or a Class IC antiarrhythmic drug 4. Hypertrophic cardiomyopathy 5. Anticipated high risk of stroke 6. Anticipated high surgical risk or risk of infection 7. Severe aortic stenosis 8. Severe proximal three vessel coronary disease (over 70% in each vessel) 9. Greater than 50% left main stem disease 10. Prior surgery or anatomical abnormality that significantly increases implant risk per physician's discretion 11. Medical conditions that preclude defibrillation testing 12. Chronic renal insufficiency including patients on dialysis 13. Subject is currently participating in another clinical investigation. 14. Pregnant or nursing subjects and those who plan pregnancy during the clinical investigation follow-up period. 15. Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with the 1-month phone follow-up requirements of the clinical investigation results.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The rate of successful defibrillation of induced VA using each of the two NV-ICD electrode configurations | During the study procedure | Successful defibrillation is defined as termination of the induced VA to sinus rhythm or other non-life threatening ventricular or escape rhythm (such as atrial fibrillation) as determined by the implanting physician. |
Other
| Measure | Time frame | Description |
|---|---|---|
| The number of acute adverse events associated with the temporary implant and defibrillation testing with the two NV-ICD electrode configurations under investigation | Within 1 month of the study procedure | Descriptive outcome summarizing possible acute adverse events with the temporary implant and defibrillation testing |
