Takotsubo cardiomyopathy associated with hyperthyroidism treated with thyroidectomy.

Takotsubo cardiomyopathy is an uncommon clinical entity, also called apical ballooning syndrome, characterized by transient systolic dysfunction of the apical and/or mid segments of the left ventricle. We report a case that highlights takotsubo syndrome in the setting of thyrotoxicosis that required thyroidectomy. The association of takotsubo syndrome and hyperthyroidism has been reported before. We found 13 previously reported cases of thyrotoxicosis-induced cardiomyopathy, most associated with Grave's disease and none treated with thyroidectomy. Awareness of this possible association is important in establishing the diagnosis and instituting proper management.
