简要总结
To evaluate safety and performance outcomes following treatment with the study device in subjects at high surgical risk, as determined by the heart team who require replacement of their native aortic valve due to symptomatic, severe, aortic valve stenosis (AS).High surgical risk is defined as predicted risk of surgical mortality ≥8% at 30 days, based on the Society of Thoracic Surgeons (STS) risk score and other clinical comorbidities unmeasured by the STS risk calculator. The total planned study duration is 20 months, which includes an initial recruitment period of 6 months and follow-up period of 12 months and 02-month’s time for post study analysis and site close outs.
