Abstract

Hyperthyroidism can be a cause of congestive heart failure. Left heart failure is occasionally complicated in patients with hyperthyroidism. However, predominant right heart failure without LV systolic dysfunction rarely develops in patients with hyperthyroidism. We present herein a case of reversible severe tricuspid regurgitation with predominant right heart failure associated with thyrotoxicosis.

Figure

• 

  Fig. 1 Initial 2D-echocardiography reveals marked dilatation of the right atrium and right ventricle and severe tricuspid regurgitation (A and C) due to incomplete coaptation of the tricuspid valve (B). LV: left ventricle, LA: left atrium.

• 

  Fig. 2 Follow-up 2D-echocardiography performed 3 months after treatment of hyperthyroidism. The size of the RA and RV is normal, and there is a markedly decreased tricuspid regurgitation (A and C) with complete coaptation of the tricuspid valve (B). LV: left ventricle, LA: left atrium.
