Abstract Objectives: We report our experience with transcatheter valve‐in‐valve implantations in patients degenerated bioprostheses aortic and mitral position. Background: Xenograft degeneration is a potential problem after biological valve replacement. Reoperation remains the gold standard very good short‐ long‐term results. In selected not suitable for surgery however, interventional techniques implantation repair may be valuable alternative treatment options regard to results of native stenosis. Methods: Five presented significant xenograft 15.4 ± 5.2 years ( n = 4) 1) Mean patient age was 82.0 6.5 predicted operative mortality 55.8% 18.9% (logistic EuroSCORE). Transcatheter performed successfully through transapical access all patients. A 23‐mm Edwards Sapien deployed into prosthesis. Results: transvalvular gradients were reduced from 31.2 17.4 19.0 12.4 mm Hg 9 3 position without regurgitation any these Two died within 30 days due low cardiac output acute hemorrhage, respectively, one whom EuroSCORE 88.9%. Conclusions: With growing need reoperative replacement elderly disproportional risks, offers an option. Although function patients, two high risk postoperative period their comorbidities, underscoring bail‐out character this procedure. © 2010 Wiley‐Liss, Inc.
