Degenerated aortic valve with indication for aortic valve replacement
mosaic Ultra
Need a aortic valve replacement

Primary Outcome Measures :
  1. Pressure gradients [ Time Frame: 240 days ]
    Investigators want too look at the effient opening area and pressure gradients of the two valves we are implanting on patients with the same size of the annulus.
