Abstract
BackgroundCerebral infarction (CI) remains one of the most common and fatal complications of infective endocarditis (IE), and the timing of surgery for IE with neurologic complications is controversial. As outcomes beyond the perioperative period have not been assessed with a meta-analysis previously, we conducted a meta-analysis comparing mid- to long-term outcomes of early and late surgery in patients with IE and neurologic complications.MethodsAll studies that investigated early and late surgery in patients with IE and neurologic complications were identified. The primary and secondary endpoints were all-cause mortality and recurrence, respectively. Hazard ratios (HRs) for all-cause mortality and recurrence were extracted from each study.ResultsOur search identified five eligible studies, which were all observational studies consisting of a total of 624 patients with IE and neurologic complications. Pooled analyses demonstrated that all-cause mortality was similar between the early and late surgery groups (HR [95% confidence interval [CI]] = 0.90 [0.49–1.64]; P = 0.10; I2 = 49%). Similarly, the recurrence rates were similar between both groups (HR [95% CI] = 1.86 [0.76–4.52]; P = 0.43; I2 = 0%).ConclusionsOur meta-analysis showed similar mortality and recurrent rates between the early and late surgery groups. The optimal timing of surgery should be individualized on a case-to-case basis.

Our search identified five eligible studies [13,14,15,16,17], which were all observational studies consisting of a total of 624 patients with IE complicated with neurologic events assigned to the early surgery (n = 252) or late surgery groups (n = 372) (Fig. 1)
Pooled analyses demonstrated that all-cause mortality was similar between the early and late surgery groups (HR [95% confidence interval [CI]] = 0.90 [0.49–1.64]; (2021) 16:49
Summary
Cerebral infarction (CI) remains one of the most common and fatal complications of infective endocarditis (IE), and the timing of surgery for IE with neurologic complications is controversial. As outcomes beyond the perioperative period have not been assessed with a meta-analysis previously, we conducted a metaanalysis comparing mid- to long-term outcomes of early and late surgery in patients with IE and neurologic complications. Cerebral infarction (CI) is still one of the most common and fatal complications of infective endocarditis (IE). The timing of surgery for IE with neurologic complications remains controversial since early surgery might result in conversion into hemorrhagic stroke as a result of systemic anticoagulation during cardiopulmonary bypass, or the exacerbation of an ischemic stroke from hypotension By using this method and updating the available studies, we conducted a meta-analysis comparing mid- to long-term
