EuroSCORE II underestimates mortality after cardiac surgery for infective endocarditis

Abstract : OBJECTIVES: To better select for patients who most likely will benefit from cardiac surgery among those with infective endocarditis (IE), we aimed to identify preoperative markers associated with poor outcome after cardiac surgery for IE, and to evaluate the accuracy of European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict mortality. METHODS: We enrolled all adult patients who underwent cardiac surgery during the acute phase of definite IE (Duke Criteria) in two referral centres for cardiac surgery. Patients were identified through intensive care unit (ICU) electronic databases, and data were collected from medical charts on standardized questionnaire. RESULTS: Between 2002 and 2013, 149 patients (117 males), with a median age of 64 years [interquartile range 52-73], fulfilled the inclusion criteria. Main complications before surgery were left ventricular dysfunction (23%), central nervous system symptomatic events (34%) and septic shock (24%). Most patients (95%) presented with valve regurgitation, and 49% had perivalvular abscess. Surgery was performed with a median delay of 12 days [5-24] after IE diagnosis, and mean EuroSCORE II was 15.8 (13.4-18.1). In-hospital mortality was 21%. Preoperative variables associated with mortality in multivariate analysis were obesity [odds ratio (OR) 3.67 [1.10-12.19], P = 0.03], vegetation \textgreater15 mm (OR 6.72 [1.46-30.98], P = 0.01), septic shock (OR 4.87 [1.67-14.28], P = 0.004) and mechanical prosthetic valve IE (OR 4.99 [1.72-28.57], P = 0.007). EuroSCORE II underestimated mortality in patients with predicted mortality over 10%. CONCLUSION: Factors independently predictive of mortality after cardiac surgery for IE are obesity, septic shock, large vegetation and a mechanical prosthetic valve IE.
