Only patients who had undergone RHC and vasodilator challenge with sodium nitroprusside were analyzed. We collected all available clinical, instrumental, and haemodynamic parameters, at baseline and after nitroprusside infusion and evaluated potential associations with post-LVAD RVF. Of the 54 patients analyzed, 19 (35%) developed RVF after LVAD implantation. Fractional area change (FAC) (OR: 0.647, CI: 0.481\u20130.871; P\u2009=\u20090.004), pulmonary artery systolic pressure (PASP) (OR: 0.856, CI: 0.761\u20130.964; P\u2009=\u20090.010), and post-sodium nitroprusside (NTP) PAPi (OR: 0.218, CI: 0.073\u20130.653; P = 0.006) were independent predictors of post-LVAD RVF. The model combining FAC, PASP, and post-NTP PAPi demonstrated a predictive accuracy of 90.7%. Addition of post-NTP PAPi significantly increased the predictive accuracy of the European Registry for Patients with Mechanical Circulatory Support right-sided heart failure risk score [79.4 vs. 70.4%; area under the curve (AUC): 0.841 vs. 0.724, P\u2009=\u20090.022] and the CRITT score (79.6% vs. 74%; AUC: 0.861 vs. 0.767 P = 0.033).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Post-NTP PAPi has observed to be an independent predictor of RVF following LVAD implantation.
