Popis: Background Liver dysfunction increases post-surgical morbidity and mortality. The Model of End-stage Liver Disease (MELD) estimates liver function but can be inaccurate in patients receiving oral anti-coagulation. We evaluated the effect of liver dysfunction on outcomes after ventricular assist device (VAD) implantation and the dynamic changes in liver dysfunction that occur during VAD support. Methods We retrospectively analyzed 255 patients (147 with pulsatile devices and 108 with continuous-flow devices) who received a long-term VAD between 2000 and 2010. Liver dysfunction was estimated by MELD and MELD-eXcluding INR (MELD-XI), with patients grouped by a score of ≥ 17 or Results MELD and MELD-XI correlated highly ( R ≥ 0.901, p p p = 0.0193). However, if MELD-XI normalized during VAD support, post-transplant survival improved and was similar to that of patients with low MELD-XI scores. Conclusions MELD-XI is a viable alternative for assessing liver dysfunction in heart failure patients on oral anti-coagulation. Liver dysfunction is associated with worse survival. However, if MELD-XI improves during VAD support, post-transplant survival is similar to those without prior liver dysfunction, suggesting an important prognostic role. We also found evidence of a transient cholestatic state after LVAD implantation that deserves further examination.
