Conclusion
Studies evaluating the durability of the RA as a conduit after TR
intervention are very limited, and few have demonstrated that injury
remains after many years. We demonstrate that after multiple years
following TR intervention, the RA shows persistent injury and should not
be utilized as a conduit for CABG. Unfortunately, chronic injury to the
RA prevents future use as a surgical revascularization conduit, thereby
depriving the patient of its well documented benefits of improved
patency and prolonged survival.
