Truncated leaflet for prosthetic heart valves

A prosthetic heart valve comprising:

• a frame being radially collapsible and expandable between a collapsed configuration and an expanded configuration, the frame including an inflow end, an outflow end, and a central longitudinal axis;
• and
• a plurality of leaflets coupled to the frame, each leaflet including:
• a leaflet free edge portion configured to abut an adjacent leaflet free edge portion when the plurality of leaflets transition from an open position to a closed position to stop fluid flow through the prosthetic heart valve;
• first and second upper edge portions on opposing sides of the leaflet, the first upper edge portion being coupled to a commissure support portion of the frame, the second upper edge portion being coupled to another commissure support portion of the frame;
• a truncated leaflet base having first and second opposing ends, wherein a straight line extending from the first end to the second end lies in a plane that is transverse to the central longitudinal axis of the frame;
• a first leaflet side edge portion extending diagonally from the first end of the leaflet base to the first upper edge portion of the leaflet, wherein the first leaflet side edge portion is coupled to a first frame portion of the frame that extends diagonally from the first end of the leaflet base to the first upper edge portion of the leaflet;
• a second leaflet side edge portion extending diagonally from the second end of the leaflet base to the second upper edge portion of the leaflet, wherein the second leaflet side edge portion is coupled to a second frame portion of the frame that extends diagonally from the second end of the leaflet base to the second upper edge portion of the leaflet;
• and
• wherein the first and second leaflet side edge portions diverge away from each other in a direction from the leaflet base toward the leaflet free edge portion.

• a second leaflet side edge portion extending diagonally from the second end of the leaflet base to the second upper edge portion of the leaflet, wherein the second leaflet side edge portion is coupled to a second frame portion of the frame, wherein the second leaflet side edge portion extends diagonally along an entire length of the second frame portion from a first end of the second frame portion adjacent the inflow end of the frame to a second end of the second frame portion at the another commissure support portion;
