Aortic Valve Repair: Does it Work? (1276 words) |
 | Functional anatomy: Because of increasing experience in aortic valve sparing surgery, and with the stentless aortic valve (xenograft, autograft and homograft), the aortic valve is now considered not only valve cusps, but a functional unit comprising the aortic annulus, the cusps, the Valsalva sinuses, the commissures, and the sino-tubular junction. |
| Patho-physiology of the aortic regurgitation: Aortic regurgitation may be secondary to a pathology of the aortic wall (aneurysm or dissection) or the cusps (prolapse, perforation, bicuspid valve or cusp retraction). |
| The aortic root with its components is considered as a functional unit, its two borders the inner (aorto-ventricular junction) and the outer (sino-tubular junction) are considered “the functional aortic annulus” (FAA) (equivalent to the mitral annulus). |

Aortic Valve Replacement - Definition, Purpose, Demographics, Description, Diagnosis/Preparation, Aftercare, Risks, ... (1797 words) |
| Aortic valve replacement is the insertion of a mechanical or tissue valve in place of the diseased native aortic valve. |
| Structural valve deterioration can occur and is higher in mechanical valves during the first five years; however, biological tissue and mechanical valves have the same failure incidence at 10 years, with a 60% probability of death at 11 years as a result of a valve-related complications. |
| Aortic valve repair by direct commisurotimy may also be successful for some cases of aortic stenosis. |
