    • Durability starts with design.

    With its supra-annular, self-expanding valve frame, Evolut™ TAVR is built on the original CoreValve™ platform which has consistently shown strong effective orifice areas (EOAs) and low gradients over time.

    How did we design for durability?

    More height

    By decoupling the native annular plane where the sealing occurs, from the working portion of the prosthetic leaflets, you can facilitate circularity and maximize leaflet coaptation.

    More surface

    Taller leaflet mounting allows for a greater distance between the commissure and the edge of the leaflet, distributing stress over a greater distance.

    More room

    The tall valve keeps the working portion above and unconstrained by the native annulus (supra-annular), allowing for a large EOA.

    Supra-annular design benefits

    Large EOAs mean less restriction of blood through the valve.

    Less restriction leads to low gradients (mean systolic gradient).

    Large EOAs have been correlated to less prosthesis-patient mismatch (PPM).

    Less PPM and low gradients after aortic valve replacement have been linked to:

    • Better survival1,2
    • Less heart failure rehospitalization2,3
    • Better valve durability4,5

    The data make the case.

    CoreValve™ and Evolut™ TAVR systems are the only platform to demonstrate a durability benefit over SAVR at five years.†,6

    Medtronic TAVR platforms demonstrated significantly lower rates of structural valve deterioration (SVD)‡ versus SAVR at five years.

    Structural valve deterioration out to 5 years

    † In pooled analysis of intermediate and high-risk patients. Devices used: CoreValve™ 88.5%/Evolut™ R 11.5%.

    ‡ Structural valve deterioration (SVD) was defined as an increase in mean gradient ≥ 10 mmHg over five years with a mean gradient ≥ 20 mmHg at last echo OR new onset/increase of central AR of ≥ moderate in severity.

    TAVR risks may include, but are not limited to, death, stroke, damage to the arteries, bleeding, and need for permanent pacemaker.
