VitaFlow LIBERTY Europa
Klinische Nachbeobachtungsstudie zum VitaFlow Liberty™ Transkatheter-Aortenklappensystem nach dem Inverkehrbringen
This is a prospective, single-arm, multi-center, observational, post-market clinical investigation to document the clinical safety and performance of MicroPort CardioFlow VitaFlow Liberty™ Transcatheter Aortic Valve System in the routine practice for the treatment of severe aortic valve stenosis. The primary endpoint is the composite rate of all-cause mortality and stroke with disability at 12 months.
Patients will receive transcatheter aortic valve replacement and examinations at the screening, procedure, discharge, and follow-up per local standard of care.

Patients with symptomatic, severe calcified aortic stenosis who are at high surgical risk.
Beschreibung
Inclusion Criteria:
- Subjects of age≥ 18 years
- Subjects with severe, symptomatic, calcific aortic stenosis who are considered at high risk for surgical aortic valve replacement (AVR).
- Subject can understand the purpose of the clinical investigation, has signed voluntarily the informed consent form and is agreeing to the scheduled follow up requirements.
Exclusion Criteria:
- Pre-existing mechanical heart valve in aortic position
- A known hypersensitivity or contraindication to all anticoagulation /antiplatelet regimens (or inability to be anticoagulated for the index procedure), to nickel or titanium, to nitinol, to dairy products, to polyethylene terephthalate (PET) or contrast media
- Ongoing sepsis, including active endocarditis
- Anatomically not suitable for the VitaFlow Liberty TAV system
- LVEF<20%
- Estimated life expectancy of less than 12 months
- Any medical, social or psychological condition that in the opinion of the Heart Team precludes the subject from receiving transcatheter aortic valve replacement
- Currently participating in another drug or device trial (excluding registries) for which the primary endpoint has not been assessed
- Inability to comply with the clinical investigation follow-up or other clinical investigation requirements
- Patients temporally unable to provide written informed consent (e. g. unconscious emergency patients)
