Abstract:
The BioValsalva (Vascutek Terumo, Renfrewshire, Scotland, UK) conduit is the first commercially available prefabricated bioprosthetic aortic valved conduit. We present a case of chronic dissection of a BioValsalva valved conduit presenting as a 7.5-cm aortic root aneurysm 1 year after a Bentall operation. Intraoperatively, the conduit was found to have dissected from the annulus upward, and the coronary buttons were avulsed from the inner layers while remaining attached to the outer layer. Both the outer layer and the coronary buttons were grossly dilatated.
