Open TAVI after resection of degenerated leaflets may be a beneficial alternative to conventional re-do surgery in high-risk patients with degenerated bioprosthetic aortic conduits.
The degeneration of bioprosthetic aortic Conduit with hemodynamic dysfunction mostly requires a re-do surgery, which is associated with an increased perioperative risk. Considering this, an open implantation of a transcatheter aortic bioprothesis (TAVI) after resection of the degenerated valve leaflets could be of great benefit, reducing cross-clamp and cardiopulmonary bypass duration, especially in combined surgery in high-risk patients. This is a case of a high-risk female (78 years, EuroScore 59%) treated with an open TAVI as an alternative to conventional valve or aortic conduit replacement for degenerative aortic valve due to endocarditis lente, 2 years following a bio-Bentall procedure.

Elghannam et al. (2018) conducted a case report in Degenerated bioprosthetic aortic conduit due to late endocarditis (n=1). Open transcatheter aortic valve implantation (TAVI) was evaluated on Procedural success and clinical recovery. Open transcatheter aortic valve implantation (TAVI) was successfully performed on a degenerated bioprosthetic valve conduit in a high-risk patient, achieving stable hemodynamics and discharge after 13 days.
