Infective endocarditis (IE) is often associated with multiorgan dysfunction and mortality. The impact of perioperative liver dysfunction (LD) on outcome remains unclear and little is known about factors leading to postoperative LD. We performed a retrospective, single-center analysis on 285 patients with left-sided IE without pre-existing chronic liver disease referred to our center between 2007 and 2013 for valve surgery. Sequential organ failure assessment (SOFA) score was used to evaluate organ dysfunction. Chi-square, Cox regression, and multivariate analyses were used for evaluation. Preoperative LD (Bilirubin > 20 mu mol/L) was present in 68 of 285 patients. New, postoperative LD occurred in 54 patients. Hypoxic hepatitis presented the most common origin of LD, accompanied with high short-term mortality. In-hospital mortality was higher in patients with preoperative and postoperative LD compared to patients without LD (51.5, 24.1, and 10.4%, respectively, p < 0.001). 5-year survival was worse in patients with pre- or postoperative LD compared to patients without LD (20.1, 37.1, and 57.0% respectively). A landmark analysis revealed similar 5-year survival between groups after patient discharge. Quality of life was similar between groups when patients survived the perioperative period. Logistic regression analysis identified duration of cardiopulmonary bypass and S. aureus infection as independent predictors of postoperative LD. Perioperative liver dysfunction in patients with infective endocarditis is an independent predictor of short- and long-term mortalities. After surviving the hospital stay, 5-year prognosis is not different and quality of life is not affected by LD. S. aureus and duration of cardiopulmonary bypass represent risk factors for postoperative LD.
