The finite elements analysis showed that the stress exerted on the outer surface of the ascending aorta in
the wrapping model (0.05–0.8 MPa) was similar to that observed in the normal aorta (0.03–0.7 MPa) and was lower
than in the model of a moderately dilated aorta (0.06–1.4 MPa). The stress on the inner surface of the ascending
aorta ranged from 0.2 MPa to 0.4 MPa in the model of the normal aorta, from 0.3 to 1.3 MPa in the model of the
dilated aorta and from 0.05 MPa to 0.4 MPa in the wrapping model.
