Cite This Study

Fujita et al. (2015) conducted a case report in Degenerated Perceval aortic sutureless prosthesis requiring a valve-in-valve procedure (n=1). Algorithm for planning and in vitro simulation (3D printing, hydrodynamic measurements, X-ray imaging) was evaluated on Feasibility and procedural success. A novel algorithm utilizing 3D printing and in vitro simulation successfully guided a transcatheter valve-in-valve procedure in 1 patient with a degenerated Perceval prosthesis.
