Multicenter StudyEarly and intermediate outcome after aortic valve replacement with a sutureless bioprosthesis: Results of a multicenter study.
The aim of this study was to evaluate the outcome of aortic valve replacement with the sutureless Perceval S aortic valve bioprosthesis (Sorin Biomedica Cardio Srl, Saluggia, Italy). ⋯ The sutureless Perceval S valve is associated with excellent early survival in high-risk patients, particularly among those undergoing an isolated procedure. Further studies are needed to prove the durability of this bioprosthesis.

Use of balloon expandable transcatheter valves for valve-in-valve implantation in patients with degenerative stentless aortic bioprostheses: Technical considerations and results.
Transcatheter valve-in-valve is an accepted treatment in high-risk patients with degenerative stented bioprostheses in the aortic position. Experience in treating stentless valves is, however, limited. Our aim was to determine the feasibility and single-center outcome of balloon expandable SAPIEN valve placement in degenerated stentless aortic valve bioprostheses. ⋯ Transcatheter aortic valve implantation after previous stentless aortic valve replacement is technically demanding but a safe and feasible approach. The early results were excellent, with consistent improvement in hemodynamics. Prospective long-term follow-up in larger series is needed to evaluate this technique further.

Acute type A aortic dissection extending beyond ascending aorta: Limited or extensive distal repair.
The aim of our study was to delineate the effect of aortic arch surgery extension on the outcomes in acute type A dissection extending beyond the ascending aorta. ⋯ Limiting the extent of surgery for type A aortic dissection to ascending aortic replacement was associated with low perioperative mortality. Thus, aortic arch repair can be deferred, because it can be performed electively with a lower mortality risk.
