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.
