Abstract:
The purpose of this study was to evaluate the impact of surgical timing on survival in patients with left-sided infective endocarditis (IE). This was a retrospective study including 313 patients with left-sided IE between 2009 and 2017. Surgery was defined as urgent (US) or early (ES) if performed within 7 or 28 days, respectively. A multivariable Cox regression analysis including US and ES as time-dependent variables was performed to assess the impact on 1-year mortality. ES was associated with a better survival (aHR 0.349, 95% CI 0.135-0.902), as US (aHR 0.262, 95% CI 0.075-0.915). ES and US were associated with a better prognosis in patients with left-sided IE.
