Amido‐amine‐functionalized multiwalled carbon‐nanotube fillers fundamentally alter the fracture and fatigue behavior of a thermosetting epoxy by initiating crazing in the material (see image). The crazing results in over an order of magnitude reduction in fatigue crack growth rates and significant improvements in fracture toughness and ductility without any softening of the material.

Stent grafting of the ascending aorta is technically feasible but should be reserved for selected high-risk patients only, preferably in centers where vascular specialists cooperate closely with interventional cardiologists. Cardiac surgery with cardiopulmonary bypass is still the gold standard to treat ascending aortic aneurysms. Stent graft exclusion of more advanced and complex ascending aortic pathology should be performed only in centers with the necessary experience in transvalvular cardiac procedures.
