Abstract
Sutureless aortic bioprostheses (SAB) are increasingly being used to provide shorter cross-clamp time. Valve-in-valve transcatheter aortic valve replacement (VIV-A) is shown to be effective and safe in the vast majority of patients with degenerated bioprosthetics, yet its' use in SAB failure is infrequent. We present a case of balloon-expandable VIV-A in an 80-year-old woman who suffered severe symptomatic aortic regurgitation in a failed Perceval S 21-mm valve. Computed tomography scan demonstrated a deformed valve. Our heart team favored a percutaneous VIV-A over reoperation due to the patients' high surgical risk. An Edwards-Sapien XT 23 mm was successfully deployed with excellent results. The patient remained asymptomatic following 6 months. As other bioprosthesis, some sutureless valves are condemned to structural valve degeneration. Because VIV-A is being established for managing degenerative bioprosthesis in high risk patients, it is cardinal to identify its role in novel degenerative sutureless valves. SAB were introduced to the clinical market only 5-7 years ago. The absence of sutures may theoretically impose risk for valve instability when adding a transcatheter sutureless valve inside the first one. Our successful experience was very reassuring. We report its feasibility because we believe it should provide support for further investigation on VIV-A within novel SAV.Entities:
