Reoperations for deteriorated stentless bioprostheses are quite challenging procedures. Calcification of the aortic annulus and of the subcoronary root makes often impossible the removal of the failed valve, living a complex Bentall operation or a high-risk transcatheter aortic valve implantation valve-in-valve procedure as the only options, particularly in cases of small-size prostheses. The Perceval sutureless prosthesis (LivaNova PLC, London, UK) can be a valid alternative for failed stentless valve replacement. We report our experience with 3 complex cases of degenerated Sorin Pericarbon Freedom prosthesis treated successfully by means of Perceval sutureless implantation and demonstrating the reproducibility and the safety of this surgical approach.
