Eligibility
Inclusion criteria
Inclusion criteria: 1. Subject is 18 years or older 2. Subject is symptomatic for aortic stenosis (AS) or mixed aortic stenosis and aortic insufficiency (AS/AI) disease for which isolated surgical aortic valve replacement without concomitant procedures is indicated according to International guidelines. 3. Surgery starts with and is intended to be completed via a minimal invasive surgical approach. MIS is defined as a non-full sternotomy approach such as partial hemi-sternotomy, right anterior thoracotomy. 4. Subject has signed and dated the investigation informed consent forms prior to any study-specific procedures are performed. 5. Subject is geographically stable and agrees to attend follow-up assessments as specified in the protocol and informed consent.
Exclusion criteria
Exclusion criteria: 1. Subject is diagnosed with pure aortic insufficiency. 2. Subject requires multiple valve replacement/repair 3. Subject has Type 0 congenital true bicuspid aortic valve (i.e. absence of raphe and commissures are positioned about 180 degrees apart) or unicuspid aortic valve. 4. Subject has severe ventricular dysfunction defined as LVEF
