Of these, 70 articles were analysed, and their data were extracted. The total number of patients included was 108\u00a0182 who underwent surgical aortic valve replacement. The incidence of PPM after surgical aortic valve replacement was 53.7% (58\u00a0116 with PPM and 50\u00a0066 without PPM). Perioperative mortality [odds ratio (OR) 1.491, 95% confidence interval (CI) 1.302\u20131.707; P\u2009&lt;\u20090.001], 1-year mortality (OR 1.465, 95% CI 1.277\u20131.681; P\u2009&lt;\u20090.001), 5-year mortality (OR 1.358, 95% CI 1.218\u20131.515; P\u2009&lt;\u20090.001) and 10-year mortality (OR 1.534, 95% CI 1.290\u20131.825; P\u2009&lt;\u20090.001) were increased in patients with PPM. Both severe PPM and moderate PPM were associated with increased risk of perioperative mortality, 1-year mortality, 5-year mortality and 10-year mortality when analysed together and separately, although we observed a higher risk in the group with severe PPM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Moderate\/severe PPM increases perioperative, early-, mid- and long-term mortality rates proportionally to its severity.
