Abstract:
The antegrade approach for aortic valve interventions is well known but has not been widely used for transcatheter aortic valve replacement (TAVR) procedures. We encountered a patient with no possibility of retrograde access due to a totally occluded abdominal aorta who had a failed attempt at apical TAVR. We describe antegrade TAVR despite occlusion of the abdominal aorta, with the arterial limb of the requisite veno-arterial loop created using bilateral arm access, a novel version of the previously described antegrade approach.
