ABSTRACT

Background: Several models exist to predict results of patients who require surgery for valvular heart disease. Among these are database models with periodic upgrading. The EuroSCORE scale uses good discrimination and calibration to predict early and later mortality for patients undergoing heart valve surgery. The objective of this study was to validate use of the EuroSCORE scale in our hospital.
Methods: Two hundred six surgeries were carried out in patients ›18 years of age during the period from January 1 to June 30, 2006. Prior to surgery, the EuroSCORE scale was applied using the standard and logistical version, stratifying patients into risk groups and comparing with obtained results.
Results: Reported mortality was 7.2% (15 patients). Average time for cross-clamping was 41 min (range: 20-170 min). Average cardiopulmonary bypass time was 59 min (range: 32-210 min). Morbidity was attributed to cardiac arrhythmias (19.7%), pneumonias (8.1%), acute or increased renal failure (9.6%), postsurgical bleeding (3.8%), and perioperative myocardial infarction (4.8%). Area under ROC curve was 0.77 and 95% CI was 0.679-0.870 of the standard EuroSCORE to predict mortality. Area under ROC curve was 0.975 and 95% CI for the logistic version was 0.984-0.998.
Conclusions: The EuroSCORE risk scale is reliable when predicting morbidity and early mortality in patients undergoing heart valve surgery in the Department of Cardiothoracic Surgery of our hospital. Results obtained by our service are similar to other centers and to those results predicted by the EuroSCORE risk scale for heart valve surgery.
