Abstract 19408: Impact of Perioperative Liver Dysfunction on In-hospital Mortality and Long-term Survival in Infective Endocarditis Patients

Background: Infective endocarditis (IE) is a dangerous disease with high mortality (20-40%). A leading cause of death is multi-organ failure (MODS) with liver dysfunction (LD) as major contributor. Data on LD in IE patients are scarce. We assessed the impact of preoperative - and newly occurring LD on in-hospital mortality and long-term survival in IE patients. Methods: We retrospectively reviewed our database for surgery of left-sided endocarditis between 1/07 and 4/13. We used the hepatic Sepsis-related Organ Failure Assessment (hSOFA) score to assess the degree of LD. We performed Chi-Square, Cox regression and multivariate analyses. Results: The 308 patients had a mean age of 62 ±13.9. Preoperative LD (hSOFA > 0, Bilirubin > 32 μmol/L) was present in 1/4 (n=81) of patients and was associated with severely elevated in-hospital mortality (51.9% vs.14.6% without preoperative LD, p<0.001). Newly-occurring postoperative LD developed in another quarter (n=57 of 227 patients without LD) of patients and was a...
