The association study will compare the allele frequencies of polymorphisms of a single

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.
