PVR was defined by echocardiography as mild (63), moderate (18), or severe (19). We found no differences according to AVA, left ventricular function, deployed stent size, calcification rate of the aortic valve, and stent position. Anatomically, the annular size and the angle between the left ventricular outflow tract (LVOT) and the ascending aorta demonstrated significant (P\u2009&lt;\u20090.05) differences in the severity of the PVR: an LVOT: ascending aorta angle &gt;12.6\u00b0, annulus area &gt;8.9\u2009cm<\/jats:italic><jats:sup><jats:italic>2<\/jats:italic><\/jats:sup><jats:italic>, and annulus diameter difference &gt;3.9\u2009mm.
