Abstract: Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and/or one or more retaining portions. The valve seat can include radiopaque markers affixed to a frame or an impermeable member. The radiopaque markers can indicate a deployment location of the valve. The docking stations can be deployed from a catheter including one or more radiopaque markers. Relative positioning of two or more radiopaque markers can provide an indication of the amount of deployment of the docking station.

Abstract: A method of implanting a prosthetic heart valve includes selecting a prosthetic heart valve. The selected prosthetic heart valve has a nominal diameter that is greater than a native annulus diameter of a native annulus by up to forty percent. The method further comprises compressing the selected prosthetic heart valve to a radially compressed configuration in which the selected prosthetic heart valve has a first diameter that is less than the nominal diameter, positioning the selected prosthetic heart valve within the native annulus, and expanding the selected prosthetic heart valve from the radially compressed configuration to a radially expanded configuration in which the selected prosthetic heart valve has a second diameter which is less than the nominal diameter by up to ten percent and which is greater than the first diameter.

Abstract: A method of implanting a prosthetic heart valve includes determining from a set of expandable prosthetic heart valves a first prosthetic heart valve. The first prosthetic heart valve has a first nominal diameter less than a native annulus diameter. The method further includes determining a first suggested expanded diameter for the first prosthetic heart valve based on the native annulus diameter, wherein the first suggested expanded diameter is greater than the first nominal diameter, and determining a pressure gradient across the first prosthetic heart valve at the first suggested expanded diameter based at least in part on pressure values from hemodynamic data of the first prosthetic heart valve. The method further includes selecting the prosthetic heart valve from the set of expandable prosthetic heart valves with the suggested expanded diameter resulting in the lowest pressure gradient for implantation from the set of prosthetic heart valves.
