Practical Approach to Transcatheter Aortic Valve Implantation and Bioprosthetic Valve Fracture in a Failed Bioprosthetic Surgical Valve
Table 1
Design, characteristics, and challenges of commonly used surgical aortic valves.
| | Leaflets mounted | Fracture potential [11] | Challenges |
| Stented valves | | | (i) Higher postprocedural gradients (ii) Coronary obstruction (externally mounted leaflets) | Sorin Mitroflow | Externally | Yes (19–21 mm) | St. Jude Trifecta | Externally | No | St. Jude Biocor Epic | Internally | Yes (21 mm) | Medtronic Mosaic | Internally | Yes (19–21 mm) | Medtronic Hancock II | Internally | No | Edwards Magna Ease | Internally | Yes (19–21 mm) | Edwards Magna | Internally | Yes (19–21 mm) | Edwards Perimount 2700 | Internally | No, but expandable | Edwards Perimount 2800 | Internally | Yes | Labcor Porcine | Internally | Yes |
| Stentless valves | | | (i) Lack of fluoroscopic markers (ii) Device malposition (iii) Coronary obstruction (iv) Paravalvular leak | Sorin Freedom | | | St. Jude Toronto | | | Medtronic Freestyle | Extended full porcine root | | Edwards Prima Plus | Extended full porcine root | |
| Sutureless | | | | Sorin Perceval | Internally | | Edwards Intuity | Internally | | Medtronic Enable | Internally | |
