Brief Summary:
Calcific aortic stenosis (CAS) is a disease characterized by progressive calcification of the aortic valve, obstructing the passage of blood from the left ventricle into the general circulation. It is the most frequent cause of valve disease in the elderly. To date, no means of preventing the disease has been discovered, and the only treatment available is valve replacement during cardiac surgery, or percutaneous implantation of a valve prosthesis when the narrowing becomes severe and causes symptoms.
The intestinal flora or microbiota, the reservoir of all the microorganisms in the gut, is implicated in numerous diseases, particularly of the intestine. But to date, no study has established a link between CAS and microbiota. The intestinal microbiota acts through molecules produced by itself or the host and passing into the bloodstream. In the pathophysiology of CAS, the valve leaflets are breached and do not heal. These molecules can enter and have beneficial or deleterious effects, in particular promoting calcification of aortic valve cells.
Concrete objectives:
Improve understanding of calcific aortic stenosis in humans Study the composition of intestinal flora in patients with aortic stenosis and compare it with healthy subjects Study the molecules in the intestinal flora likely to be involved in the development of aortic stenosis in humans.
