Polymeric valvular structure and method of preparation thereof

A prosthetic heart valve, comprising:

• a frame (101);
• one or more sealing means (102) attached to the frame (101);
• and
• a polymeric film cut to a predefined shape to yield a valvular structure (103), the valvular structure (103) attached to the frame (101);
• wherein, the polymeric film is made from a polymer solution, the polymer solution including a polymer dissolved in at least one solvent, the polymer solution subjected to a drying technique at a first pre-defined temperature(s) and a first pre-defined pressure(s) for a first pre-defined time period(s);
• wherein the polymer is dehydrated;
• wherein, the at least one solvent is anhydrous;
• wherein the polymeric film subjected to a drying technique at a second pre-defined temperature(s) for a second pre-defined time period(s).
