Key result
Valve-in-valve implantation of the Allegra transcatheter heart valve into a degenerated sutureless surgical aortic bioprosthesis was successful and yielded excellent hemodynamic results.
Why the study?
The Allegra transcatheter heart valve had never been used for transcatheter valve-in-valve implantation inside the latest-generation sutureless surgical aortic valve bioprosthesis.
Does the Allegra transcatheter heart valve provide successful valve-in-valve implantation in a degenerated sutureless surgical aortic bioprosthesis?
Case Report
Does the Allegra transcatheter heart valve provide successful valve-in-valve implantation in a degenerated sutureless surgical aortic bioprosthesis?
This case report provides the first evidence of successful valve-in-valve implantation of an Allegra prosthesis into a degenerated sutureless surgical aortic valve.
Demonstrates Allegra VIV feasibility in sutureless SAV; leaves open durability, safety, and generalizability in larger cohorts.
Transcatheter aortic valve-in-valve implantation (VIV) is increasingly being used to successfully treat degenerated surgical aortic valve bioprostheses (SAVs). The new self-expanding transcatheter heart valve Allegra, from New Valve Technology with its special implantation mechanism, has proven its safety and feasibility for patients with degenerated SAVs, but it has never been used in the latest-generation sutureless SAV. To the best of our knowledge, this is the first description of the successful VIV of the Allegra prosthesis into a degenerated sutureless SAV, and the procedure yielded an excellent postinterventional hemodynamic results.

Vondran et al. (2021) conducted a case report in Degenerated sutureless surgical aortic valve bioprosthesis. Allegra transcatheter heart valve was evaluated on Postinterventional hemodynamic results. Valve-in-valve implantation of the Allegra transcatheter heart valve into a degenerated sutureless surgical aortic bioprosthesis was successful and yielded excellent hemodynamic results.
