Studies were stratified into two subgroups: the first consisting of those which included only patients undergoing valve surgery (n=19) and the second including TAVI or mixed (TAVI and surgical) populations (n=9). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were recorded or determined, and a summary diagnostic performance was obtained by a random effects model. Pooled forest plots and summary receiver operating characteristic curves were also analysed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The overall sensitivity of CCTA to diagnose significant CAD varied between 18 studies, ranging from 85% to 94%; the pooled sensitivity over all 28 studies was 91% (95% CI 88% to 93%) and the specificity was 88% (95% CI 84% to 91%). The pooled PPV was 78% (95% CI 72% to 83%), while the NPV was 95% (95% CI 93% to 97%).
