Abstract

BACKGROUND
Heart failure is a rare condition of thyrotoxicosis. We report a case of thyrotoxicosis-inducing heart failure.
CASE REPORT
A 29-year old female had been suffered from thyrotoxicosis for 3 years without proper medication. She complained progressive dyspnea and palpitation with atrial fibrillation with rapid ventricular response. Marked cardiomegaly, and severe right ventricular dysfunction with biatrial enlargements were found on Two-dimensional (2D) echocardiography. We treated her with medications for heart failure and thyrotoxicosis, and the patient's symptoms and objective cardiac functions are improved after two weeks.
CONCLUSION
Severe heart failure caused by thyrotoxicosis could be reversible with proper management. Patients who have thyrotoxicosis should be assessed closely, and suitable treatment can markedly improve the patient's prognosis.

Figure

• 

  Fig. 1 Initial electrocardiography (ECG) and follow-up ECG. Initial atrial fibrillation (A) was converted to normal sinus rhythm (B).

• 

  Fig. 2 Initial chest X-ray and follow-up chest X-ray. Her initial chest X-ray (A) showed marked cardiomegaly with right side pleural effusion and follow-up chest X-ray showed improved cardiomegaly (B).

• 

  Fig. 3 Initial 2D echocardiography and follow-up 2D echocardiography. Initial biatrial enlargement, severe right ventricular dysfunction, moderate left ventricular dysfunction (A) were improved on follow-up 2D echocardiography (B).
