Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: September 25, 2018

Detailed Description

This is an international multicenter, prospective, non-randomized clinical investigation without concurrent or matched control, designed to assess the mid-term safety and performance of the Portico valve in patients with severe symptomatic aortic stenosis whom are high risk for surgical valve replacement. The primary endpoint is 1 year all-cause mortality. In addition, the performance and safety profile of the Portico valve will be further evaluated at 30 days, 1 year, and annually through 5 years post-implant. The investigation will be conducted at approximately 65 centers in approximately 15 countries in Europe, Middle-East, Africa, Canada, Australia and New Zealand.

    • The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying the extent of heart failure. It classifies patients in one of four categories based on their limitations during physical activity: Class I – No symptoms and no limitation in ordinary physical activity; Class II – Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity; Class III – Marked limitation in activity due to symptoms; Class IV – Severe limitations.

  • Mean Quality of Life Assessment
    • Time Frame: 30 days and 1 year post implant
    • EuroQuol-5 Dimensions (EQ5D) is a standardized instrument for use as a measure of health outcome applicable to a wide range of health conditions and treatments. A visual analog scale (VAS) for health is also included in the measure as a patient-reported estimate of overall health status. This scale ranges between 0-100, where 0 is ‘the worst health you can imagine’ and 100 is ‘the best health you can imagine’.

Exclusion Criteria:

  • Any case in which the Portico Valve would not be indicated for the patient as per current instructions for use (i.e any "off-label" use). – Patient has any other aortic valve than tricuspid one. – Patient has a prosthetic valve or ring in the aortic position. – Patient needs a concomitant structural heart procedure.. – Patient needs the usage of an embolic protection device. – Patient is unwilling or unable to comply with all clinical investigation-required follow-up evaluations. – Patient is pregnant
