Abstract OBJECTIVES Cardiac surgery in patients with infective endocarditis (IE) and preoperative intracranial haemorrhage (pre-ICH) is a highly debatable issue, and guidelines are still not well defined. The goal of this study was to investigate the effect of cardiac surgery and its timing on the clinical outcomes of patients with IE and pre-ICH. METHODS We did a single-centre retrospective analysis of data from patients with preoperative brain imaging who had surgery for left-sided IE between January 2007 and May 2018. RESULTS Among the 363 patients included in the study, 34 had pre-ICH. Hospital mortality was similar between the patients with and without pre-ICH (29% vs 27%, respectively; P = 0.84). Unadjusted, postoperative neurological deterioration appeared higher in patients with pre-ICH (24% vs 17%; P = 0.35). In multivariable analysis, pre-ICH did not qualify as an independent predictor for either postoperative neurological deterioration [odds ratio 1.10, 95% confidence interval (CI) 0.44–2.73; P = 0.84] or hospital mortality (odds ratio 1.02, 95% CI 0.43–2.40; P = 0.96). Postoperative partial thromboplastin time was significantly elevated in 4 patients with relevant post-ICH compared with those patients without relevant post-ICH (65.5 vs 37.6, respectively; P = 0.004). CONCLUSIONS Pre-ICH was not an independent predictor for postoperative neurological deterioration or hospital mortality in patients with IE. Postoperative coagulation management seems to be crucial in patients with IE with ICH. Although this is to date the largest monocentric study addressing surgical decision and timing, the number of patients with pre-ICH was low. Therefore, these conclusions should be regarded with caution; randomized clinical trials are needed. Infective endocarditis (IE) is a life-threatening disease often associated with neurological complications in 20–50% of the patients [1, 2].
