La configuration de l'anastomose proximale n'est pas aussi importante que son emplacement. In addition to human valves, Rajamannan and colleagues83 discovered that osteochondrogenic differentiation and signaling could be found in cultured valvular cells and rabbits with high cholesterol. Dans ce cas, ces feuillets se sont rigidifiés (sténose aortique sévère) ce qui entraine un . Because osteoprotegerin serves as a decoy receptor for the pro-osteoclastic factor receptor activator of nuclear factor-B, it is a natural anti-osteoproliferative factor. This condition is also known as aortic calcification. It is still critical to take care of it on a regular basis to ensure that the condition does not worsen. L'une des causes les plus fréquentes de sténose de la valve aortique est la calcification dégénérative de la valve aortique liée à l'âge. Le traitement chirurgical des anévrysmes supravalvulaires consiste au replacement de l'aorte par un tue supracoronaire alors que les anévrysmes de la racine de l'aorte peuvent nécessiter en plus un geste sur la valve aortique. It is assumed that an aortic valve calcification will increase by 24.5% per year on average. If any of these symptoms occur, your doctor will need to examine your calcium level and determine whether you have chronic kidney disease (CKD). If vascular calcification causes arteries to harden, the heart will have to pump more blood in order to maintain blood pressure.
