Objective: To evaluate the course of left-sided infective endocarditis (LsIE) in patients with liver cirrhosis (LC) analyzing its influence on mortality and the impact of surgery.
Methods: Prospective cohort study, conducted from 1984 to 2013 in 26 Spanish hospitals.
Results: A total of 3.136 patients with LsIE were enrolled and 308 had LC: 151 Child-Pugh A, 103 B, 34 C and 20 were excluded because of unknown stage. Mortality was significantly higher in the patients with LsIE and LC (42.5% vs. 28.4%; p < 0.01) and this condition was in general an independent worse factor for outcome (HR 1.51, 95% CI: 1.23-1.85; p < 0.001). However, patients in stage A had similar mortality to patients without cirrhosis (31.8% vs. 28.4% p = NS) and in this stage heart surgery had a protective effect (28% in operated patients vs. 60% in non-operated when it was indicated). Mortality was significantly higher in stages B (52.4%) and C (52.9%) and the prognosis was better for patients in stage B who underwent surgery immediately (mortality 50%) compared to those where surgery was delayed (58%) or not performed (74%). Only one patient in stage C underwent surgery.
Conclusions: Patients with liver cirrhosis and infective endocarditis have a poorer prognosis only in stages B and C. Early surgery must be performed in stages A and although in selected patients in stage B when indicated.
