How Does the Ascending Aorta Geometry Change When It Dissects?

The purpose of this study is to delineate changes in aortic geometry and diameter due to dissection.Aortic diameter is the major criterion for elective ascending aortic replacement for dilated ascending aortas to prevent aortic dissection. However, recommendations are made on the basis of clinical experience and observation of diameters of previously dissected aortas.Six tertiary centers on 2 continents reviewed their acute aortic dissection...
