ICE-Guided False Lumen Occlusion Following Combined TAVR and TEVAR.

ABSTRACT:

Background

Concomitant severe aortic stenosis and descending aortic pathology pose unique challenges for transcatheter treatment strategies.

Case summary

A 75-year-old man with end-stage renal disease and chronic descending aortic dissection presented with symptomatic severe aortic stenosis. Preprocedural imaging revealed a heavily calcified aortic valve and a large thoracic aortic aneurysm with dissection. He underwent successful transfemoral transcatheter aortic valve replacement using a 65-cm-long DrySeal sheath, immediately followed by thoracic endovascular aortic repair. Two weeks later, residual false lumen perfusion was treated with a custom-made false lumen occluder under intracardiac echocardiography guidance. The patient recovered uneventfully.
