Data provided by company:

• It is based on the ATS 3f® Aortic Bioprosthesis and a self-expanding Nitinol™ frame to hold the valve in its position
• Foldable into a small diameter, it can be implanted through a minimally invasive technique such as ministernotomy or thoracotomy. It has three equine pericardial leaflets giving it a tubular design that allows for decreased leaflet stress and preservation of aortic sinuses

Comments Echocardiography:

• The 2 year EOA and transvalvular gradient results of reference number 2 are not size-specific but based on a mixed group of 40 patients with 3f aortic bioprosthesis of sizes 21 to 29mm.

Comments Surgery:

• Three pericardial leaflets shaped in the form of a tube, design compensates naturally occurring changes in the aortic root, low incidence of central prosthetic regurgitation, design for even distribution of stresses
