1. A valve prosthesis comprising:
an expandable annular support structure including:
a proximal frame portion having an inflow end and an outflow end, wherein the inflow end of the proximal frame portion flares radially outward with the proximal frame portion in a radially expanded configuration;
exactly three commissure posts, wherein each of the commissure posts includes:
a proximal end terminating at the outflow end of the inflow frame portion;
an elongated slit extending through the commissure post;
a first edge extending longitudinally;
a second edge extending longitudinally and disposed opposite the elongated slit relative to the first edge;
