SAT-225 A Rare Cause of Cardiogenic Shock

Abstract

Background: Rare cases of pheochromocytoma are associated with stress induced Takotsubo cardiomyopathy, occurring in approximately 3% of secreting pheoochromocytoma and paraganglioma (PPGL). Case: A 39-year-old female with a history of hypertension and anxiety disorder, re-presented to the ED within 24 hours with headache, vomiting and severe hypertension (BP 205/70 mmHg). She rapidly developed acute pulmonary oedema and cardiogenic shock. ECG revealed dynamic ST-segment abnormalities and troponin rise peaked at 38,000 ng/L (N < 16ng/L). The coronary angiography excluded any coronary artery lesion. Echocardiography revealed severe global hypokinesis with an ejection fraction of 5% and evidence of apical ballooning. A bedside abdominal ultrasound revealed 7cm left adrenal mass confirmed by computed tomography (CT). Investigations revealed a metanephrine level of > 13,760 pmol/L (N < 900 pmol/L) and normetanephrine of > 60,780 pmol/L (N < 500 pmol/L). Her clinical status deteriorated despite on diuretics, inotropes and mechanical ventilation. Extra-corporeal membrane oxygenation (ECMO) was implanted. Alpha adrenergic blockades were initiated followed by beta blockers, during which control of blood pressure was achieved. Her haemodynamic status improved and ECMO removed 8 days post-implantation. Two weeks after discharge from hospital, she underwent uncomplicated open adrenalectomy; histologic examination of the mass confirmed the pheochromocytoma diagnosis. Reference 1.
