Massive Pericardial Effusion: A Rare Cardiac Manifestation in Hypothyroidism

Pericardial effusion is a common finding in hypothyroidism patients. We had three cases of hypothyroidism with cardiac manifestations of massive pericardial effusion accompanied by echocardiographic evidence of tamponade. After diagnosis, pericardiocentesis and treatment with hormonal drugs were commenced, as a result of which the symptoms were alleviated. Tamponade is a serious, albeit rare, clinical manifestation of hypothyroidism. It is, therefore, advisable that hypothyroidism be considered in all patients with pericardial effusion (Iranian Heart Journal 2010; 11 (3):43-46).
