An arteriovenous loop can facilitate transseptal mitral valve-in-valve implantation when massive biatrial enlargement precludes standard delivery.
An arteriovenous loop technique may facilitate transseptal mitral valve-in-valve implantation when massive biatrial enlargement precludes standard delivery.
Transseptal mitral valve-in-valve (ViV) implantation is an established therapy for failed surgical bioprostheses. However, massive biatrial enlargement can preclude delivery, leading to procedural failure.
Li et al. (2026) studied this question. An arteriovenous loop can facilitate transseptal mitral valve-in-valve implantation when massive biatrial enlargement precludes standard delivery.
