Two-dimensional speckle-tracking echocardiography was used to assess LS. RASP was defined as an apical-to-basal LS ratio &amp;gt;3.0 in \u22653 out of six left ventricular walls. The primary endpoint was 2-year cardiovascular (CV) mortality. RASP was present in 19.2% of patients and independently predicted 2-year CV mortality (hazard ratio [HR] 2.01, 95% CI 1.22\u20133.29, P = 0.006). Low serum albumin (&amp;lt;4.0 g\/dL; HR 2.40, 95% CI 1.50\u20133.84, P &amp;lt; 0.001) and low BMI (\u226425.5 kg\/m2; HR 1.71, 95% CI 1.07\u20132.73, P = 0.025) were also independent predictors. A composite risk score (0\u20133 points) was constructed using these three factors. Two-year CV mortality increased progressively with higher scores: 6.3% for score 0, 11.4% for score 1, 27.2% for score 2 and 35.3% for score 3 (log-rank P &amp;lt; 0.001). High-risk patients (score \u22652) had a more than threefold increase in adjusted mortality risk (HR 3.42, 95% CI 2.14\u20135.48, P &amp;lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>RASP, particularly when combined with hypoalbuminemia and low BMI, identifies a high-risk phenotype associated with adverse outcomes after TAVR.
