A prosthetic heart valve () which includes a stent () having three leaflets () attached thereto is provided. The stent () is compressible so as to be capable of being introduced into a patient's body through a minimally invasive procedure and has a ring-like body () defining in its height three arch-shaped elements (). Each element () includes an arc () and a pair of haunches () extending from opposite sides thereof, with three commissural posts () formed by the haunches () of adjacent elements (). The leaflets () each have an attachment edge () and a free edge () with a belly () extending therebetween. The leaflets () are movable between a coapted condition, in which the free edges () abut and prevent fluid flow through the valve (), and an open condition, in which fluid flow through the valve () is permitted. The leaflets () are made from a polymeric material and are moulded directly onto the stent () so as to provide for continuous attachment thereof.
