[Acute pulmonary edema as a first manifestation of hyperthyroidism in a pregnant woman. Report of one case]. / Edema pulmonar agudo como primera manifestación de hipertiroidismo en una mujer embarazada.

We report a 36 year-old pregnant woman who presented with acute pulmonary edema in the absence of preexisting cardiac disease. On admission she was on sinus rhythm and her blood pressure was mildly elevated. No cardiac abnormalities were detected by color Doppler echocardiography and no ischemic changes were seen on the electrocardiogram. Cardiac enzymes were normal. Thyroid function tests were diagnostic for hyperthyroidism. She was treated with propylthiouracil and propranolol and discharged in good conditions seven days after admission. This case emphasizes the need to consider hyperthyroidism as the cause of unexplained pulmonary edema in young patients with no history of heart disease who present with heart failure.

[Right ventricular assistance with a centrifugal pump. Report of two cases]. / Asistencia ventricular derecha con bomba centrífuga.

Acute right ventricular failure after cardiac surgery occurring in the first postoperative hours is associated with a bad prognosis. We have used a centrifugal pump either for left, right or biventricular assistance. However, the use of this device for pure right ventricular assistance is rare. We report a 30 year-old female undergoing a mitral valve replacement and a 42 year-old male undergoing a cardiac transplantation, who had a successful right ventricular assistance using a centrifugal pump, due to a failing right ventricle, as the result of insufficient myocardial protection and severe pulmonary hypertension. These two cases illustrate the value of the mechanical ventricular assist device for the treatment of right heart failure.
