The FlexNav Delivery System (small and large) is commercially available in Europe. The 23 mm, 25 mm, 27 mm, 29 mm, and 35 mm valves and their loading systems are currently CE Marked.\n\nThe Navitor Valve maintains several design features of the first-generation Portico Valve including same valve sizes and use range (except for the addition of the 35 mm valve to expand the use range), open stent cell design to provide easy coronary access and blood flow, repositionable with the ability to re-sheath and retrieve, leaflets derived from pericardial bovine tissue, and intra-annular placement of leaflets\u002Fcuff within the stent frame for early valve function to maintain hemodynamic stability during implant.\n\nThe Study will enroll subjects that, after comprehensive Heart Team evaluation, are scheduled for treatment with the Navitor\u002FNavitor Vision Valve according to standard of care at up to 25 experienced TAVI implant centers across Europe and UK. All sites must either have prior Portico or Navitor\u002FNavitor Vision TAVI system experience. Subjects who provide informed consent for the collection of their clinical data in this Study, will undergo Navitor\u002FNavitor Vision Valve implantation via a transfemoral or alternative access (subclavian or axillary) approach using the site's anesthesia protocol for TAVI procedures.\n\nIn the Study, the point of enrollment is defined as informed consent signing, whereas the point of registration is defined as the insertion of the FlexNav Delivery System (loaded with a Navitor\u002FNavitor Vision Valve) into the subject's vasculature (the subject is considered attempted with Navitor\u002FNavitor Vision Valve implantation at this point). Only registered subjects will be included in the analysis.\n\nThe endpoints of interest will be defined according to VARC-3 definitions. Subjects participating in the Study will be followed for a total of 5 years with data collected at, baseline, procedure, prior to hospital discharge, and follow-up at 30 days, 12 months and annually thereafter up to 5 years.\n\nThe expected duration of enrollment is 12 months, and the total duration of the Study including final data cleaning, reporting, and site close-out is expected to be approximately 6.5 years.\n\nThis Study will enroll subjects of all genders who have symptomatic, severe AS, either in native or in a surgical bioprosthetic valve and are indicated for TAVI implantation. The latter can also be predominantly regurgitant to be suitable for enrolment. Subjects must meet all general eligibility criteria for the TAVI procedure and provide written informed consent prior to sites collecting any clinical data for this Study.\n\nThe operative risk determination of study candidates will be done by the local heart team. The assessment of surgical risk will include the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Risk Calculator score and\u002For EuroSCORE II, indices of frailty, and comorbidities not captured by risk calculators, as described below, and current TAVI practice guidelines. A member of the site's clinical investigation team previously trained to the protocol must evaluate patients for the general eligibility criteria, and if applicable, will enter the patients into the site- specific Pre-Screening Log. A patient who does not satisfy all general eligibility criteria prior to informed consent is considered a screen failure and should not be enrolled in the Study.\n\nSites will ask patients meeting general inclusion criteria and no general exclusion criteria to sign an Informed Consent form following the established Informed Consent process if they wish to participate in the Study.\n\nA patient is considered enrolled in the Intensive Study from the moment the patient provides written informed consent.\n\nEach subject meeting all general eligibility criteria who is enrolled and receives the Navitor valveshall be followed up until completion of the recommended 5 year follow-up period; however, a subject's participation in any clinical study is voluntary and the subject has the right to withdraw at any time without penalty or loss of benefit. Conceivable reasons for discontinuation may include, but not be limited to, the following:\n\n* Subject death\n* Subject undergoes the interventional procedure but exits the operating room without an implanted Navitor Valve; in this case, follow-up is limited to 30 days post-procedure for safety assessment\n* After Navitor implantation, subject receives another aortic valve intervention during follow-up (eg, valve in valve intervention, surgical AVR, etc): in this case, follow-up is limited to 30 days after the additional procedure for safety assessment\n* Subject voluntary withdrawal\n* Subject lost-to follow-up as described below\n* Subject's follow-up is terminated Sites must collect and document the reason(s) for subject discontinuation. Investigators must also report this to their respective EC as defined by their institution's procedure(s).\n\nNo additional follow-up is required or data recorded from subjects once withdrawn from the Study, except for the status (deceased\u002Falive).\n\nIn case of subject withdrawal of consent, the site should make attempts to schedule the subject for a final follow-up visit. At this final follow-up visit, the subject will undergo the following assessments (routine assessments during follow-up visit) and related data will be collected when available:\n\n* Echocardiography to include comprehensive transthoracic echocardiogram, including assessment of aortic valve gradients (mean and peak), areas, indices, degree of regurgitation, cardiac output and cardiac index, left ventricle systolic function (global and segmental)\n* Adverse Event assessment","This Study will enroll subjects of all genders who have symptomatic, severe AS, either in native or in a surgical bioprosthetic valve and are indicated for TAVI implantation.
