Takotsubo cardiomyopathy as the primary manifestation of decompensated Graves' disease

Abstract

Takotsubo cardiomyopathy (TCM) is characterized by transient left ventricular dysfunction with apical ballooning, usually observed in postmenopausal women after a stressful event. We discuss a rare presentation of TCM induced by thyrotoxicosis secondary to Graves' disease. This case raises interesting questions about the pathogenesis, diagnosis, and management of TCM.

Learning objectives

1. To recognize hyperthyroidism as a possible etiology of takutsubo cardiomyopathy.

2. To identify the effect of radioiodine contrast on diagnosis of some types of takutsubo cardiomyopathy.
