Genetics of Aortic Stenosis: From Family Forms to the Common Forms

The association study will compare the allele frequencies of polymorphisms of a single nucleotide (SNP) in the population of individuals with aortic stenosis compared to a control population. Patients will be included only if they are suffering from a typical form of tight and surgical tricuspid aortic stenosis. Patients will therefore only included if they are suffering from aortic stenosis, the surface is less than 1 cm² and if histological analysis or failing intraoperative findings of the surgeon showed a tricuspid aortic stenosis.
