This study used the German registry of acute aortic dissection type A (GERAADA) score to predict thirty-day mortality in an aortic center in the United States. Six-hundred-eighty-five patients who underwent surgery for acute type A aortic dissection were included. Thirty-day mortality was 12 percent. The GERAADA score had very good discrimination power (area under the receiver operating characteristic 0.762). The observed versus estimated mortality ratio was 0.543, indicating the model overestimated risk. The authors concluded the GERAADA score is a good tool to estimate thirty-day mortality, although it may overestimate the risk in experienced aortic centers.
