The Portico THV is a fully repositionable, self-expanding intra-annular valve within a nitinol frame. The valve cuff is made from porcine pericardium and is sutured to the stent frame. The valve and valve cuff are processed using Linx anticalcification technology. During the study, the Portico THV was available in 4 sizes (23, 25, 27, and 29 mm) that covered native aortic annulus diameters of 19 to 27 mm.
