BackgroundEuroSCORE II is a mortality risk score for cardiac surgery in adults. This version is widely validated and compared with other scores in Europe, North America, and Asia.AimTo determine the performance of the EuroSCORE II for the prediction of mortality in cardiac surgeries in Latin America.Material And MethodsA systematic review was carried out of studies from Latin American countries evaluating the performance of EuroSCORE II in cardiac surgery. The inclusion criteria were patients older than 18 years, from Latin America, published in English, Spanish and/or Portuguese, between the years 2012 to 2020, with the term "EuroSCORE II" in the title. Observed mortality and estimated mortality data by EuroSCORE II were extracted. The calibration was determined by the observed/estimated mortality ratio and the discrimination was evaluated using receiver operating characteristic (ROC) curves.ResultsFour articles met the inclusion criteria, including 8372 patients. The average patients' age was 62 years and 34% were women. The observed and Euroscore II estimated mortality figures were 7.08 and 3.89%, respectively. The average area under the curve of ROC curves was 0.77 and the observed/ estimated mortality ratio was 2.04.ConclusionsIn these studies, EuroSCORE II underestimated mortality in cardiac surgery.
