A 60 years old female with hypothyroidism due to Hashimoto disease admitted to our hospital. Electrocardiogram showed low voltage in all leads and chest roentogenogram showed cardiomegaly and right pleural effusion. Echocardiogram revealed marked left ventricular symmetric hypertrophy and moderate hypertrophy of right ventricular free wall with moderate pericardial effusion. After administration of levothyroxine sodium, biventricular hypertrophy and pericardial effusion gradually decreased as her thyroid hormone level elevated to the normal range. Many reports of myxoedema heart were published and some of them showed that the administration of thyroid hormone improved ventricular hypertrophy. But symmetric hypertrophy of left ventriculum like this case is very rare.
