Cardiac amyloidosis is a restrictive cardiomyopathy with a potentially severe prognosis that can be life-threatening. It is linked in the vast majority of cases to a light chain deposition of immunoglobulin or transthyretin. Although myocardial involvement is predominant, other locations are possible: the atrioventricular conduction system, coronary arteries and valve leaflets. In systematic histological analyzes, deposits of amyloidosis infiltrating the aortic valve have been reported with a frequency of up to 74% for degenerative RA. The nature of these deposits has never been established because the immunostaining carried out all remained negative, probably due to decalcification prior to cutting. Currently, these deposits are considered to be local degenerative phenomena without clinical repercussions. However, the use of bone scintigraphy has shown a high prevalence, between 14 and
