Background: The introduction of endovascular aortic arch repair (EAR) represents a paradigm shift in the management of complex arch pathologies usually treated with open surgical repair (OSR). This shift in treatment of aortic arch disease has also been accompanied with a rise in commercial interest in EAR resulting in the development of several endografts. However, the RELAY™ Branched by Terumo Aortic can be considered the prime endograft choice. In this international original study, a retrospective comparative analysis of international prospective outcomes data on the single- and double-branch RELAY stent grafts is provided. Methods: International data on EAR procedures carried out from January 2019 to January 2022 using the single- and double-branch RELAY endograft configurations were collected prospectively. Follow-up data were collected at 30 days, 6 months, 12 months, and 24 months postoperatively. Retrospective descriptive analysis, logistic regression, and Kaplan-Meier analysis were performed. Results: A total of 125 patients were included, out of which 17 (13.6%) received the single-branch RELAY and 108 the double-branch device. In the single-branch group, no mortalities, strokes, or reinterventions were recoded over 24 months of follow-up. The rates of these outcomes were higher in the other group; however, the differences did not reach significance. Target vessel patency was maintained at 100% throughout the study period with the single-branched RELAY. Overall, our Kaplan-Meier analyses proved that both configurations of RELAY Branched yield excellent short- and mid-term survival and freedom from reintervention. Conclusions: Our series has clearly demonstrated that EAR using RELAY Branched is a highly efficacious strategy that yields very favorable results which can be considered superior to other EAR devices as well as OSR. Nevertheless, it seems that clinical outcomes with the single-branch RELAY are more optimal than with the double-branch device.

Abstract

Background: The introduction of endovascular aortic arch repair (EAR) represents a paradigm shift in the management of complex arch pathologies usually treated with open surgical repair (OSR). This shift in treatment of aortic arch disease has also been accompanied with a rise in commercial interest in EAR resulting in the development of several endografts. However, the RELAY™ Branched by Terumo Aortic can be considered the prime endograft choice. In this international original study, a retrospective comparative analysis of international prospective outcomes data on the single- and double-branch RELAY stent grafts is provided. Methods: International data on EAR procedures carried out from January 2019 to January 2022 using the single- and double-branch RELAY endograft configurations were collected prospectively. Follow-up data were collected at 30 days, 6 months, 12 months, and 24 months postoperatively. Retrospective descriptive analysis, logistic regression, and Kaplan-Meier analysis were performed. Results: A total of 125 patients were included, out of which 17 (13.6%) received the single-branch RELAY and 108 the double-branch device. In the single-branch group, no mortalities, strokes, or reinterventions were recoded over 24 months of follow-up. The rates of these outcomes were higher in the other group; however, the differences did not reach significance. Target vessel patency was maintained at 100% throughout the study period with the single-branched RELAY. Overall, our Kaplan-Meier analyses proved that both configurations of RELAY Branched yield excellent short- and mid-term survival and freedom from reintervention. Conclusions: Our series has clearly demonstrated that EAR using RELAY Branched is a highly efficacious strategy that yields very favorable results which can be considered superior to other EAR devices as well as OSR. Nevertheless, it seems that clinical outcomes with the single-branch RELAY are more optimal than with the double-branch device.
