| Detailed Study Protocol Parameters |
| Study Objectives |
The study objective is to characterize the acute safety and effectiveness of the Navitor Transcatheter Aortic Heart Valve through 5 years post procedure in patients with symptomatic, severe aortic stenosis who are considered high or greater surgical risk. The study is a prospective, multi-center, single-arm study.
|
| Study Population |
Patients with symptomatic, severe aortic stenosis who are considered high or extreme surgical risk.
|
| Sample Size |
All living subjects enrolled under the IDE Portico NG Approval study, including all analysis, roll-in, and continued access cohorts
|
| Key Study Endpoints |
The safety and effectiveness endpoints include, but are not limited to: all-cause mortality, all-cause and disabling stroke, life-threatening and major bleeding events, stage 2 or 3 acute kidney injury, major vascular complications, paravalvular aortic regurgitation, myocardial infarction, re-operation for valve-related dysfunction, rehospitalization for valve-related symptoms or worsening congestive heart failure, new permanent pacemaker implantation, new-onset atrial fibrillation, functional status as evaluated by New York Heart Association (NYHA), health status as evaluated by Medical Outcomes Study Questionnaire Short Form 36 Health Survey (SF-36) through 1 year, and hemodynamic performance metrics by echocardiography.

| Interim or Final Data Summary |
| Interim Results |
Safety Results;
Site-reported K-M rates at 3 Years:
All-cause mortality: 23.9%
All-cause stroke: 9.0%
Myocardial infarction: 6.2%
Re-operation for valve-related dysfunction: 0.8%
Rehospitalization for valve-related symptoms: 3.2%
New permanent pacemaker implantation: 24.8%
New-onset atrial fibrillation: 10.6%
Effectiveness Results:
Mean aortic valve gradient: 7.3±3.3mmHg [24 months]
Effective orifice area (EOA): 2.0±0.5 cm2 [24 months]
Paravalvular Leak (moderate/severe): 0.6% [24 months]
New York Heart Association (NYHA) functional class (Class III/IV): 4.8% [36 months]

|
| Actual Number of Sites Enrolled |
26 sites in the United States, Australia, Denmark, Italy, and the United Kingdom (19 US, 7 OUS)
|
| Patient Follow-up Rate |
Patient status known at 3Y = 86.5% ((167 visits completed + 58 deaths) / 260 implanted)
