Independent investigators collected outcome data and information. The primary study outcome was the difference in \u0394LAS (postTAVR\u2013preTAVR) between patients those met the main clinical endpoint (a composite of cardiovascular mortality and heart failure hospitalisation) and those not meeting the endpoint.<\/jats:p>\n                  <jats:p>During a median follow-up of 31 months, 35 patients (35%) met the combined clinical endpoint. The difference between LAS post-TAVR and LAS pre-TAVR (\u0394LAS) was significantly larger in patients who met the combined endpoint (HR=0.76 (0.67\u20130.86); p&lt;0.001). Multivariate logistic regression analysis including \u0394LAS, EuroSCORE II and left ventricular ejection fraction showed that \u0394LAS (HR=0.80, p&lt;0.001) was the only independent predictor of the combined clinical endpoint. Finally, a Kaplan-Maier analysis showed that patients with a \u0394LAS above its median value had a significantly better event-free survival compared with those below the median
