Summary
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.
Eligibility Criteria
Inclusion Criteria
- The subject has been successfully implanted with a commercially approved LivaNova bioprosthetic valve according to the instructions for use (IFU)
- The subject has signed the informed consent.
- The subject is at least 18 years of age at the time of implant and consent signature
- The subject will be available for post-operative follow-up through one year
Exclusion Criteria
- The subject has a planned concomitant cardiac procedure other than coronary artery bypass graft (CABG) and septal myectomy, including MAZE procedures, atrial fibrillation surgery, and left atrial appendage exclusion or resection, or has a prosthetic heart valve or annuloplasty ring in any position
- The subject has any medical condition requiring long term (> 6 months) anticoagulation or dual antiplatelet therapy
- The subject has any clinical condition precluding the use of CT imaging with contrast
- The subject had a stroke or myocardial infarction (STEMI and NSTEMI) within 30 days of the planned valve implant surgery
- The subject has active endocarditis, myocarditis, or sepsis
- The subject is in cardiogenic shock manifested by low cardiac output and needing hemodynamic support
- The subject is already included in another clinical trial that could confound the results of this clinical investigation
