Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, randomized controlled (1:1) multicenter trial. The pilot study will be conducted up to three clinical sites in the United States. The primary purpose of this study is to compare the overall safety and efficacy between the leadless pacemaker and left bundle area pacing.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, randomized controlled (1:1) multicenter trial. The pilot study will be conducted up to three clinical sites in the United States. This study is designed to compare the safety and effectiveness of two types of pacemaker treatments: leadless pacemakers and left bundle area pacing. Patients who's heart rhythm indicate a degree of heart block that slows the heart beat and decreases the amount of blood the heart is pumping to the rest of the body will be identified by physicians to participate. This study seeks to improve our understanding of heart rhythm disorders to allow us to provide the best treatment for our patients.

6. Life expectancy \> 1 year
7. Female subject of childbearing potential is not pregnant, not breast feeding, does not plan to be pregnant during the course of the study, and agrees to use a highly effective contraceptive method (i.e. IUD, birth control, vasectomized partner, sexual abstinence, etc.) during the course of the study.

7. History of mitral or tricuspid valve surgery
8. Preexisting implanted pacemaker or ICD or lead
9. Subject is allergic to titanium
10. Life expectancy \< 1 year
11. Recurrent or high risk of infections
12. Active malignancy requiring systemic chemotherapy or local chest radiation
13. Subject has myocardial infarction, unstable angina, cerebrovascular accident, or heart failure admission within 3 months of the baseline visit
14. CABG, valve surgery or PCI within the last 3 months except TAVR
15. Other major cardiac surgery within the last 6 months
16. Persistent and permanent atrial fibrillation diagnosed by a healthcare provider
17. NYHA class 3 or 4 Heart Failure

18. Evidence of renal injury (12 hours post-TAVR)
19. Access site complication(s) post-TAVR
20. Suspicion of stroke/cerebrovascular accident (CVA) or transient ischemic attack (TIA) within 12 hours post-TAVR
21. Physician suspicion that ambulation to pre-TAVR activities post-pacemaker implantation would be unattainable
22. Other post-TAVR complications that in the opinion of the investigator may seriously confound study outcomes
