| Detailed Study Protocol Parameters |
| Study Objectives |
The purpose of the post-approval study (PAS) is to evaluate the long-term safety of the dual-chamber Aveir Leadless Pacemaker device (aka DR LP) using real-world evidence (RWE) methods. The study utilizes a real-world evidence method merging multiple real-world datasets from Abbott and CMS to assess the Aveir DR LP safety in a large patient population.
|
| Study Population |
All de novo patients implanted with the Aveir DR LP who successfully link to Medicare FFS data will be included in the analysis, starting at market approval and continuing for approximately one year or longer, if necessary, to include a minimum of 1,805 subjects. Patients implanted with an Aveir atrial LP only (i.e., without a ventricular LP) will be analyzed in additional analysis and not in the primary and secondary analyses.

| Key Study Endpoints |
Primary Endpoints:
1. Acute complications through 30 days post implant procedure
2. Freedom from chronic complications from 31 days through 5 years post implant procedure
Secondary Endpoints:
1. Complication rate of the Aveir DR LP for key individual acute and chronic complications
2. Care of subjects at the end of device service
Descriptive Endpoints and Analyses:
1. Rates of other procedure-related acute complications
2. Survival at 5 years
3. Device longevity
4. Device longevity by device (atrial, ventricular)
5. Acute complications by device (atrial, ventricular)
6. Chronic complications by device (atrial, ventricular)
Additional analyses include:
1. Cohort demographics and comorbidities
2. Device-device interaction
3. Effect of implanter experience with DR leadless pacemakers
4. Acute and chronic complications in patients with an atrial LP only
5. Battery performance
6. i2i performance
7. Acute and chronic complications in all Aveir patients (de novo and non de novo)

| Follow-up Visits and Length of Follow-up |
The study completion is 5 years after the final implant.

| Interim or Final Data Summary |
| Actual Number of Patients Enrolled |
345
|
| Actual Number of Sites Enrolled |
147
|
| Final Safety Findings |
Freedom from key acute complications through 30 days post implant was 91.2% (95% CI 87.6%-93.8%) as of the cut-off date for the 345
enrolled subjects. Enrolled subjects include patients with prior Cardiovascular Implantable Electronic Devices (CIED) as well as de
novo patients (patients with no prior CIED implants).
Freedom from key chronic complications from 31 days to 10 years post implant was 99.7% event-free survival rate through a maximum
follow-up time of 150 days.
