lüll Which available transapical transcatheter valve fits into degenerated aortic bioprostheses?Ferrari E; Marcucci C; Sulzer C; von Segesser LKInteract Cardiovasc Thorac Surg 2010[Jul]; 11 (1): 83-5The transapical transcatheter aortic valve implantation (TA-TAVI) in degenerated aortic bioprosthesis is an emerging therapy for surgically non-amenable patients. However, the presence of different types of aortic bioprostheses (stented and stentless), available in different sizes (19-27 mm), can be at the origin of important mismatches between the malfunctioning, degenerated aortic valves and the inner stent-valves implanted through transapical accesses (23 and 26 mm Edwards Sapien transcatheter stent-valves). We report an emergency TA-TAVI treatment of a severely regurgitant degenerated 23 mm Mitroflow aortic bioprosthesis (Sorin Group, Milano, Italy) implanted seven years earlier in an 80-year-old lady, and we reviewed the current available literature about transapical 'valve-in-valve' procedures to analyze the hemodynamic results and the ideal 'prosthesis-to-prosthesis' match.|*Bioprosthesis[MESH]|*Heart Valve Prosthesis[MESH]|*Prosthesis Failure[MESH]|Aged, 80 and over[MESH]|Aortic Valve Insufficiency/diagnostic imaging/etiology/physiopathology/*therapy[MESH]|Aortic Valve/diagnostic imaging/physiopathology/*surgery[MESH]|Cardiac Catheterization/*instrumentation[MESH]|Echocardiography, Transesophageal[MESH]|Female[MESH]|Heart Valve Prosthesis Implantation/adverse effects/*instrumentation/methods[MESH]|Hemodynamics[MESH]|Humans[MESH]|Prosthesis Design[MESH] |
