This is a prospective, interventional, multi-center trial to report the overall incidence of reduced leaflet motion identified by CT imaging in patients receiving a commercially approved LivaNova bioprosthetic aortic heart valve up to 1 year post implant, on patients that are off anticoagulation for at least 30 days. A minimum of 200 subjects with evaluable 4D CT scans will be enrolled at approximately 15 investigational sites where the devices are commercially available. For asymptomatic subjects, PIs and subjects will be blinded from the CT imaging results and from the Core Lab findings.
