VI2Ta2 S2C2Ore: A new score system for in hospital mortality in acute aortic dissections

INTRODUCTION: Aortic dissections classification systems have always been an argument of debate. It is well known that none of the described classifications is complete and easy at the same time. While the more used classification is currently the Stanford classification, it is clear that type A and B dissections prognosis can dramatically vary, depending on many different characteristics that they can present. The aim of this study was to propose a new severity score system that could reflect the risk of in hospital mortality of acute aortic dissections EVIDENCE ACQUISITION: Through a review of the literature, studies describing significant predictors of in hospital mortality of any type of aortic dissection were searched and selected by predefined selection criteria. EVIDENCE SYNTHESIS: Nine studies met the criteria and were finally analyzed. The Odds Ratios of the reported predictors were the basis to the drawing of the score system. Sixteen main in hospital mortality predictors were found, 14 of which described in more than one study. They were combined into a new severity score system that we named VI2TA2 S2C2ORE. CONCLUSIONS: This is a simple risk score that we propose as a first assessment risk-evaluating tool. We look forward to validate it and to describe specific in hospital mortality risk ranges once it will be adopted.
