1. A low profile balloon expandable artificial prosthetic heart valve, adapted for transcatheter implantation comprising:
a valve frame of cylindrical structure which consists of a first section, a supporting section, defining a frame interior; and
a single piece of continuous polymer material attached to the valve frame by electrospinning wherein an excess of the continuous polymer material forms a cuff of the polymer material which is inseparably integrated with the valve frame so that the valve frame supporting section is embedded and covered from inside of the valve frame and further covers an outside of the frame with the cuff material; further, a portion of the cuff is folded into the frame the frame interior and in the frame first section, it the cuff is formed into a valve leaflets in bicuspid or tricuspid configuration and in the said supporting section the continuous polymer is attached to the frame and to frame posts, each frame post having a central opening and longitudinal openings, an excess of the cuff material is pressed into the longitudinal openings in at least one of the posts to secure the cuff to the frame.
