ABSTRACT
We present a 58-year-old female with a past history of a pituitary adenoma resected two years prior to admission who developed polymorphic ventricular tachycardia and cardiogenic shock requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO). We noted that the patient had stopped taking all of her medications six months prior to presentation. An extensive workup revealed acute panhypopituitarism with secondary hypothyroidism, secondary adrenal insufficiency, and central diabetes insipidus. She was immediately initiated on thyroid and adrenal hormone replacement therapy as well as fluid replacement. Within five days of her medical treatment, the patient's cardiac function improved and she was successfully weaned from VA-ECMO and subsequently discharged home with appropriate hormone replacement therapy.
