Aortic root replacement (ARR) is a well-described and highly efective technique for treating aortic root pathologies with excellent long-term outcomes and reported mortality ranging between 4-10% in specialized aortic centers [1-3]. Coronary button reimplantation is arguably one of the most challenging aspects of ARR operations, requiring mobilization and reattachment of the coronaries to the root graft. Reimplantation can be complicated by damage to the coronary buttons, coronary occlusion or malperfusion, and bleeding. The dissected arch is subject to a very low rate of complications after type A dissection repair The residual dissected aorta is subject to higher rate of degeneration and lifethreatening complications Computational Fluid Dynamics Analysis of Hemodynamics Stress to Guide Treatment Strategy in Aortic Dissections Domenico Calcaterra, Liza Shrestha2 , Kevin Harris, Amit Sharma, Mohammad Bashir1, Kalpaj Parekh1, Jesse Manunga, Panos Vardas and Sarah Vigmostad2
