Parasternal Access for ShockS and Pacing With an acUtely Placed Less-invasive Lead for EV-ICD (PASS PULL EV-ICD) Study

Parasternal Access for ShockS and Pacing With an acUtely Placed Less-invasive Lead for EV-ICD (PASS PULL EV-ICD) Study

The PASS PULL EV-ICD Study is a prospective, multi-center, single-arm study without concurrent or historical controls. This initial concept feasibility study is primarily intended to demonstrate that the EV-ICD Lead can be safely positioned within the anterior mediastinum as intended using the AtaCor delivery system. The study will secondarily characterize the ability for the EV-ICD Lead to facilitate VF sensing and defibrillation.

The primary objective of the study is to demonstrate that the AtaCor EV-ICD Lead can be safely positioned within the anterior mediastinum as intended using the EV-ICD Dilator and EV-ICD Delivery Tool. The study will secondarily characterize the ability for the EV-ICD Lead to facilitate VF sensing and defibrillation.

Up to 3 Investigational Sites will participate with up to 65 subjects enrolled in the study. Patients undergoing de novo or replacement ICD procedure will be eligible for participation. Study participation requires acute evaluation of the EV-ICD Lead during the index procedure. Echocardiography will be used to evaluate any new or worsening pericardial effusions. A follow-up visit will occur 7-10 days post-removal via phone, video call, or in-person. Participation will end after completion of the 7-10 days post-removal visit. The Study is expected to last up to 3 months for enrollment.

9. Inability to give an informed consent to participate in the Study

   Known prior history for any of the following:

10. Structural abnormalities of the heart that may increase risk of the study procedure or an obstructed/restricted pathway into the mediastinum for the EV-ICD Dilator, EV-ICD Delivery Tool and EV-ICD Lead as assessed from available CT or Echocardiography.

11. Uncontrolled paroxysmal, persistent or permanent atrial fibrillation

12. Median or partial sternotomy

14. Significant anatomic derangement of or within the thorax (e.g., pectus excavatum, significant scoliosis)

15. Thoracic radiation therapy, pneumothorax, pneumomediastinum or other medical treatments/conditions which may complicate the EV-ICD Lead insertion procedure

16. Pericardial disease, pericarditis and mediastinitis

17. Medical treatments, surgeries or conditions that increase the potential for pericardial adhesions

18. FEV1 < 1.0 Liter

19. Surgically corrected congenital heart disease (not including catheter-based procedures)
