Abstract

Abstract Introduction Even after advances in medical and surgical treatment, infective endocarditis is associated with substantial morbidity and mortality. The aim of this study was to evaluate postoperative mortality in surgically treated infective endocarditis patients and its correlation with the European System for Cardiac Operative Risk Evaluation (EuroSCORE) I. Methods This retrospective observational study included 43 patients treated surgically for infective endocarditis, between 2014 and 2019, at a tertiary care center. Mortality in surgically treated infective endocarditis patients was determined in terms of frequency (%). Patients were divided into two groups—survivors and nonsurvivors (died within 30 days of surgery). Mean EuroSCORE I of survivors and nonsurvivors was compared using the unpaired t-test with equal variance. A correlation was sought between mortality and EuroSCORE I as well. The prediction ability of EuroSCORE I for mortality was determined by the area under receiver operating characteristic curve. Results Out of 43 patients who underwent surgery for infective endocarditis,11 patients (25.58%) died. Mean EuroSCORE I was 15.90 ± 2.02 in nonsurvivors and 7.84 ± 3.19 in survivors. EuroSCORE I was significantly higher in nonsurvivors (p < 0.05). The area under curve value was 0.9744 (p < 0.001), thus showing that EuroSCORE I predicts mortality in surgically treated infective endocarditis patients. Conclusion The 30-day mortality in patients who underwent surgery for infective endocarditis was 25.58%. There is a significant correlation between EuroSCORE I and mortality. A EuroSCORE I value >14 predicts mortality in surgically treated infective endocarditis patients with sensitivity and specificity of 90.91 and 90.63%, respectively.
