Prosthetic replacement of the aorta is a risk factor for aortic root aneurysm development

Background. Noncompliant prostheses are used in aortic replacement. We hypothesized that this leads to increased distension and wall stress in the aortic root because of the loss of ventriculo arterial coupling. Methods. Pressure relations in the aortic root caused by changes of aortic elasticity si...
