Official Title: Estimation of Myocardial Iron Overload by 3 Tesla MRI and Cardiac Functional Consequences in Patients With HFE Hereditary Haemochromatosis. Pilot Study

Brief Summary:

Hereditary haemochromatosis (HHC) is a frequent disease in Brittany (5 to 7‰), responsible first for biological disorder in blood iron parameters and minor clinical disorders, before evolving to potential life-threatening consequences such as diabetes, liver cirrhosis and congestive heart failure.

The improvement of screening and treatments made those severe affections rare enough not to evaluate myocardial iron overload a systematic part of the starting check-up. Nonetheless this myocardial iron overload might have severe implications on cardiac function on a long term basis.

A single trial was conducted on limited number of patients with 1.5 Tesla MRI, which showed a myocardial iron overload (defined by a myocardium T2* value <20ms) in 19% of the subjects.

The main objective of this study is to precisely estimate cardiac iron overload in treatment naive patients with newly diagnosed HFE hereditary haemochromatosis with a 3 Tesla MRI, more sensitive than the 1.5 Tesla one, in order to later appreciate its correlation with cardiac morbidity in HHC.
