Key result
Axillary conduit TAVR with passive carotid shunting enables successful valve deployment without neurologic complications.
Why the study?
Alternate access solutions are needed in patients where standard transfemoral delivery of TAVR devices is deemed prohibitive.

Using an axillary conduit combined with a TCAR sheath system provides a feasible alternative access strategy for TAVR that allows for passive cerebral perfusion and embolic protection in patients with prohibitive iliofemoral and aortic arch anatomy.
Alternate access solutions are needed in patients where standard transfemoral delivery of transcatheter aortic valve replacement (TAVR) devices is deemed prohibitive. We present a case of a 78-year-old male patient with a past medical history significant for severe aortic arch disease, peripheral artery disease, and symptomatic aortic stenosis requiring an alternative access solution for TAVR. The combination of an axillary conduit with a transcarotid arterial revascularization arterial and venous sheath was utilized to create an access point for the TAVR device and an avenue for cerebral embolic protection with passive cerebral perfusion.

Barber et al. (2026) conducted a case report in Symptomatic aortic stenosis with complex vascular anatomy (n=1). TAVR via axillary conduit with passive femoral to carotid cerebral perfusion shunt was evaluated on Procedural success and neurological complications. TAVR via an axillary conduit with a passive femoral to carotid cerebral perfusion shunt successfully facilitated valve deployment without neurologic complications.
