[Value of total thyroidectomy in amiodarone-induced hyperthyroidism].

The potential severity of amiodarone-induced hyperthyroidism, particularly in severe cardiopathy cases, necessitates a regular clinic and biologic thyroid control. The break in amiodarone and a medical treatment (synthetic antithyroid drugs, steroids, perchlorate of potassium) can be ineffective. The authors report the case of a patient with an right ventricle arythmogenic dysplasia, without thyroid history, who came back 3 years after the introducing of amiodarone with major hyperthyroidism.
