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.
