Does the distal anchor balloon technique facilitate transcatheter aortic valve delivery in patients with challenging anatomy such as a surgical tissue prosthesis with a Dacron conduit?
The distal anchor balloon technique can be a useful alternative strategy to facilitate transcatheter aortic valve delivery in challenging anatomies such as a surgical tissue prosthesis with a Dacron conduit.
Transcatheter aortic valve replacement has been established as an advanced therapeutic modality for severe aortic stenosis. Despite procedural advancements, anatomical variations may hinder successful prosthetic valve delivery in certain cases. Delivering a relatively bulky prosthesis through a constricted and extensively stenosed surgical bioprosthetic valve remains challenging. Such cases require alternative procedural strategies to enable smooth device navigation. In this case, the presence of a surgical tissue prosthesis with a Dacron conduit resulted in stacking of the delivery system within the aortic arch. An anchor balloon (20/45 mm) over a buddy wire was used to assist in guidewire compression and effective valve advancement.
Loncar et al. (2026) conducted a case report in Severe aortic stenosis (n=1). Distal anchor balloon technique was evaluated on Effective valve advancement. The use of a distal anchor balloon (20/45 mm) over a buddy wire successfully facilitated guidewire compression and transcatheter aortic valve advancement in a challenging anatomical case.
