A prosthetic heart valve made of hyperelastic material not limited to Neoprene or Silicon Rubber, to be used in place of heart valves affected by valvular disease. The invention comprises of two rings, the outer one for mounting and affixing the valve in place in whichever position as may be required, and the inner one which makes up the body of the valve. The valving mechanism is made up of flap means affixed to the body at the root, and shaped in such a way that the valve automatically closes when reverse flow is encountered. The proposed invention provides better haemodynamic conditions and reduces the regurgitation of blood to a minimum.
