The receiver operating characteristic and Kaplan\u2013Meier curves were generated to assess the predictive value of preoperative LVEDD dilation for poor patient prognosis (readmission or death within 1 year postoperatively), as well as its effects on the readmission risk owing to heart failure, and complications and survival rates within 1 year postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Significant differences were observed between the two groups in B\u2010type natriuretic peptide, creatinine, aortic valve area, transfemoral access, aortic valve peak velocity, mean transvalvular pressure gradient, LVEDD, left ventricular end\u2010systolic dimension, left atrial dimension, interventricular septal thickness, relative wall thickness, left ventricular mass index, left ventricular ejection fraction, E\/A ratio, E\/e\u2032 ratio, and stroke volume index.
