Stress Cardiomyopathy Precipitated by Withdrawal of Epoprostenol.

We describe a case of stress-induced cardiomyopathy following epoprostenol withdrawal. A patient with pulmonary arterial hypertension presented with a malfunctioning Hickman catheter. Inappropriate withdrawal of epoprostenol resulted in shock. Evaluation confirmed stress-induced cardiomyopathy. Restarting epoprostenol resolved the electrocardiographic and echocardiographic abnormalities. This case meets Taskforce on Takotsubo Syndrome Stress-Induced Cardiomyopathy criteria.
