Cardiac tamponade revealing hypothyroidism was reported in our department in 3 cases. Clinical, electrocardiographic, echocardiographic and biological data were examined. These patients were characterized by a cardiovascular risk factor of smoking, clinically by polypneic dyspnea (25, 30 cycles/min) vs. 19 cycles/min respectively, low blood pressure (70/50, 90/60) vs. 100/75 mmhg, significantly higher heart rate (120, 135) vs. 87 beats/min, normal sinus rhythm, microvoltage, flat T wave, and clear yellowish pericardial fluid (2 of 3). Biologically, anemia with hb respectively (6g, 9g and 9.8g); Tsh (15.9µUI, 90µUI, 110µUI); T3 (0.17; 0.20; 0.26) One patient (33%) had echocardiographic evidence of tamponade without a paradoxical pulse and was successfully treated with thyroxine without pericardial drainage. Tamponade with sinus tachycardia, hypothyroidism should be strongly suspected, although an urgent pericardiocentesis should be performed.
