Composite porcine valve that preserves the natural shape of the tissue collagen. The valve is mounted on a low-profile stent with which a zero pressure fixation is applied, making the TLPB Porcine Heart Valve Bioprosthesis a stronger, more elastic and durable implantable device. Low-Profile Stent TLPB projection in the aorta is between 6-9 mm. In the left ventricle it is between 8-10 mm; Reduced interference from the coronary ostia or rupture of the left ventricle; Allows for supra-annular implantation.
