We sought to assess the prognostic impact of the PAPi in unselected patients with aortic stenosis (AS) undergoing aortic valve replacement (AVR).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We studied consecutive patients with severe AS (n = 487, 74 \u00b1 10 years, 58% males) undergoing right heart catheterization prior to AVR with post-AVR follow-up of several years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean PAPi was 4.7 \u00b1 3.3, and the mean values in the four PAPi quartiles were 2.1 \u00b1 0.5, 3.2 \u00b1 0.3, 4.5 \u00b1 0.5 and 8.9 \u00b1 4.2. Patients in the lowest PAPi quartile had similar AS severity, symptoms, B-type natriuretic peptide and surgical risk compared with patients in higher quartiles. The lowest PAPi quartile had the lowest PAPP and the highest mRAP and only a slightly reduced stroke volume index (SVI) but the highest pulmonary artery capacitance (PAC). After a median post-AVR follow-up of 45 months mortality did not differ across PAPi quartiles (log rank P = 0.50), which was independent of the AVR mode. However, all contributors of the PAPi equation, that is, higher PAPP, lower PAC (i.e., stroke volume divided by PAPP), lower SVI and higher mRAP were associated with increased mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In unselected patients with severe AS, the PAPi did not predict post-AVR mortality.
