Key result

Transcarotid TAVI achieves successful deployment without complications in severe AS with double aortic arch.

n=1

Key Points

Describe transcarotid transcatheter aortic valve implantation in an elderly patient with severe aortic stenosis and a vascular ring caused by a double aortic arch.
Evaluated an 85-year-old woman with symptomatic severe aortic stenosis and a double aortic arch forming a complete vascular ring on preprocedural CT.
Selected transcarotid access via surgical cutdown of the left common carotid artery under regional anesthesia due to an unfavorable, angulated dominant left aortic arch and hypoplastic right aortic arch.
Successfully implanted a 23-mm SAPIEN 3 Ultra RESILIA valve without procedural complications.
Postprocedural 4D-flow MRI demonstrated a marked increase in flow volume with prominent streamline visualization of accelerated flow.

Population

An 85-year-old woman with symptomatic severe aortic stenosis and a double aortic arch vascular ring underwent transcarotid transcatheter aortic valve implantation.

I

Intervention

Transcarotid transcatheter aortic valve implantation (TAVI) via the left common carotid artery using a 23-mm SAPIEN 3 Ultra RESILIA valve, performed under regional anesthesia.

O

Outcome

Procedural success and procedural complicationssafety

Implication

Transcarotid access represents a feasible and less invasive alternative strategy for TAVI in patients with complex vascular anatomy such as a double aortic arch that precludes traditional transfemoral access.

Domoto et al. (2026) conducted a case report in Symptomatic severe aortic stenosis with vascular ring due to double aortic arch (n=1). Transcarotid transcatheter aortic valve implantation (TC-TAVI) was evaluated on Procedural success. Transcarotid transcatheter aortic valve implantation was successfully performed without procedural complications in a patient with severe aortic stenosis and a complex double aortic arch.
