    Analysis population for this measure includes only patients who had the assessment completed. Patients who completed a visit but were unable to have NYHA Class assessed are not presented.

    9 months post index procedure

  • EuroQol 5-dimension, 5-level (EQ-5D-5L) Quality of Life Questionnaire

    Patients are asked to rate their perception of their health on the day they complete the assessment on a scale of 0 to 100. A score of 100 means the patient has the best health they can imagine, and a score of 0 means the worst health they can imagine. The reported value is the average of all patient scores reported at the specified time point for the specified patient group.

    30 Days

  • EuroQol 5-dimension, 5-level (EQ-5D-5L) Quality of Life Questionnaire

    Patients are asked to rate their perception of their health on the day they complete the assessment on a scale of 0 to 100. A score of 100 means the patient has the best health they can imagine, and a score of 0 means the worst health they can imagine. The reported value is the average of all patient scores reported at the specified time point for the specified patient group.

Study Arms (1)

Analysis Population

EXPERIMENTAL

The analysis population will include patients considered at high or extreme surgical risk, who have met all inclusion criteria, have not met any exclusion criteria, have signed an Ethics Committee (EC) approved Informed Consent, and, at the minimum, the FlexNav delivery system entered his/her vasculature for an attempted Portico or Navitor Valve implant

Device: Transcatheter Aortic Valve Replacement

Interventions

Transcatheter Aortic Valve Replacement for the treatment of patients with severe aortic stenosis

Analysis Population

Eligibility Criteria

Age60 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject must provide written informed consent prior to any clinical investigation-related procedure.
  • Are \>60 years of age in host country, have severe symptomatic (NYHA class ≥ II) aortic stenosis (AS), at high or extreme surgical risk and have been identified as a candidate for a Portico or Navitor valve implant.
  • Subjects must have a Society of Thoracic Surgeons (STS) score of ≥7% OR documented heart team agreement of high or extreme risk for surgical aortic valve replacement due to frailty or co-morbidities not captured by the STS score.

You may not qualify if:

  • Have tested positive for the Corona Virus Disease 2019 (COVID-19) virus at any time AND currently have residual signs or symptoms associated with the COVID-19 virus (eg. evidence of thrombosis, damaged/inflamed heart muscle, damaged/inflamed lung tissue, etc.)
  • Have sepsis, including active endocarditis
  • Have any evidence of left ventricular or atrial thrombus
  • Have vascular conditions (i.e. caliber, stenosis, tortuosity, or severe calcification) that make insertion and endovascular access to the aortic valve improbable
  • Have a non-calcified aortic annulus
  • Have congenital bicuspid or unicuspid leaflet configuration
  • Are unable to tolerate antiplatelet/anticoagulant therapy
  • Are pregnant at the time of signing informed consent
  • Are currently participating in a drug or device study that may impact this study (unless prior sponsor approval for co-enrollment is granted)
