[Lipomatous hypertrophy of the atrial septum. Cardiac-induced syncope in hamartoma of the right heart atrium].
A previously well 40-year-old woman suddenly collapsed and had to be resuscitated by an emergency physician. Admitted to hospital she remained unconscious and needed artificial respiration. Diagnostic tests failed to find evidence for pulmonary embolism, myocardial infarction or myocarditis. ECG monitoring in the intensive care unit merely revealed occasional unifocal ventricular premature systoles. Echocardiography was within normal limits. She remained in coma without spontaneous respiration. Cranial computed tomography and serial electroencephalograms indicated brain death. Autopsy revealed lipomatous hypertrophy (hamartoma) of the atrial septum with extensive bleeding into it as the most likely cause of (unrecorded) malignant cardiac arrhythmias.
