Key result
Ross plus ascending aorta replacement shows no difference in autograft outcomes versus Ross alone.
Why the study?
The impact of ascending aorta replacement combined with the Ross procedure on autograft root distensibility and valve function was unclear.
Does replacement of the ascending aorta combined with a Ross procedure affect autograft root distensibility and function compared to a Ross procedure alone?
Cohort (n=40)
Does replacement of the ascending aorta combined with a Ross procedure affect autograft root distensibility and function compared to a Ross procedure alone?
Replacement of the ascending aorta with a noncompliant prosthesis during a Ross procedure does not appear to negatively impact autograft root dimensions, distensibility, or valve function.
Autograft parameters similar after Ross with or without ascending aorta replacement; leaves open long-term durability in larger cohorts.
In this study we aimed to assess the autograft root dimensions, distensibility, and autograft valve function in patients after Ross operation combined with replacement of the ascending aorta compared to patients that underwent Ross operation only. Forty patients received a Ross operation, and in 12 of them an additional replacement of the ascending aorta was performed. Autograft root dimensions, distensibility, and valve function were assessed by echocardiography. There were no differences in root size, distensibility, and valve function between groups. Our preliminary results indicate that replacement of the ascending aorta with a noncompliant prosthesis has no effect on the autograft root.

Leyh et al. (2003) conducted a cohort in Combined pathology of the aortic valve and ascending aorta (n=40). Ross operation combined with replacement of the ascending aorta vs. Ross operation only was evaluated on Autograft root dimensions, distensibility, and autograft valve function. Replacement of the ascending aorta combined with a Ross procedure showed no differences in autograft root size, distensibility, and valve function compared to a Ross procedure alone.
