Transapical Access for Antegrade Catheterization of the Inner Branches of an Arch Stent-Graft Deployed Distal to an Ascending Arch Stent-Graft

Abstract

Propose: To describe a technique for antegrade cannulation and bridging of the supra-aortic branches through a transapical access in the treatment of an arch aneurysm using combined ascending and branched arch stent-grafts. Technique: An 81-year-old man with a past history of open infrarenal aortic repair, emergent endovascular aortic repair for thoracic aortic rupture, and later perivisceral 4-vessel branched endovascular repair of type I thoracoabdominal aneurysm presented for repair of a concomitant 7.5-cm arch aneurysm. Because of a 44-mm ascending aorta, a tapered 50/44-mm ascending stent-graft was delivered through a transapical access to establish an adequate landing zone before implantation of a 46-mm inner branched arch device via a transfemoral route. Innominate and left subclavian arteries were antegradely cannulated and bridged through the existing transapical path. Conclusion: Our case demonstrates the feasibility of transapical access for cannulation of an arch branched device, while introducing the theoretical possibility of completing the entire procedure through a transapical access.
