Original ArticleMeta-analysis on the Performance of the EuroSCORE II and the Society of Thoracic Surgeons Scores in Patients Undergoing Aortic Valve Replacement
Section snippets
Methods
A literature review was performed through PubMed, Scopus, Science Direct and Google for any study published since 2011 and evaluating the performance of the ESII score and the STS score in the same population of patients undergoing SAVR or TAVR. The word employed in the search was “EuroSCORE II”. Reference lists of obtained articles were searched as well. This study was not financially supported.
Results
A literature search was performed on March 16, 2014 and yielded 138 articles of which 107, 8, 9, 10, 11, 12, 13, 14, 15, 16 reported on data of interest and fulfilled the inclusion criteria of the present study (Fig 1). No prospective study was available for this analysis.
Table 1 summarizes the main characteristics of these studies. These studies included 13,856 patients with 577 operative deaths. SVAR was performed in 11,791 patients and TAVR in 2,065 patients. The pooled operative mortality
Discussion
This pooled analysis showed that current O/E mortality ratios estimated by either the ESII score or the STS score approached 1.0 in patients undergoing aortic valve replacement. This is a remarkable improvement particularly for the ESII score, as the logistic EuroSCORE was shown to significantly and markedly overpredict the operative risk.17 In fact, the O/E mortality ratio estimated by the logistic EuroSCORE in patients undergoing aortic valve surgery with or without coronary surgery was shown
