Abstract

BackgroundThe optimum timing of surgical intervention in complicated left-sided infective endocarditis is not well established. Guidelines from various professional societies are not consistent regarding this. Data concerning this remains limited with conflicting results. MethodsThe national inpatient database (NIS) was used to identify patients hospitalized from the year 2016 to 2020 for infective endocarditis and who underwent surgical intervention for complicated left-sided endocarditis. Primary and secondary outcomes were analyzed in patients who had surgical intervention within 7 days (early surgery group) and after 7 days (late surgery group) of the index hospitalization. ResultsPrimary outcome [composite of all-cause death, acute cerebrovascular accident (CVA), peripheral septic emboli, intracranial or intraspinal abscess, and cardiac arrest] was better in the early surgery group compared to the late surgery group 32.6 % vs 45.1 % [adjusted Odds ratio (aOR) = 0.59, 95 % Confidence interval (CI) = 0.52–0.67, P value ≪ 0.001]. This was mainly due to better incidence of acute CVA (15.7 %vs 24 %, aOR = 0.59, CI = 0.50–0.69, P value ≪ 0.001), peripheral septic emboli (18.5 % vs 27.3 %, aOR = 0.60, CI = 0.52–0.70, P value ≪ 0.001) and intracranial/intraspinal abscess (1.2 % vs 4.74 %, aOR = 0.24, CI = 0.14–0.38, P value ≪ 0.001). There is no difference in the incidence of all-cause in-hospital death (7.57 % vs 7.75 % aOR = 0.97, CI = 0.77–1.23, P value = 0.82) or cardiac arrest (3.4 % vs 3.54 %, aOR = 0.96, CI = 0.68–1.35, P value = 0.80). ConclusionSurgical intervention within 7 days of index hospitalization is associated with a better incidence of acute CVA, peripheral septic emboli, and intracranial or intraspinal abscess but not with a better incidence of all-cause in-hospital death.
