Takotsubo cardiomyopathy after microwave ablation of hepatocellular carcinoma

Abstract

Takotsubo cardiomyopathy is a form of stress cardiomyopathy that can clinically mimic an acute ST-segment elevation myocardial infarction (STEMI). It involves transient anomalies in left ventricular wall motion secondary to myocardial stunning. Specific causes have still not been elucidated, and several mechanisms have been proposed, including catecholamine surges following intense emotional or physical stress. We present a case of a 74-year-old woman, diagnosed with Takotsubo cardiomyopathy following percutaneous microwave ablation of hepatocellular carcinoma. Although Takotsubo cardiomyopathy comprises a small percentage of acute coronary syndrome presentations, it should be considered in the differential for acute cardiac events as its management varies compared to other more common forms of acute cardiac events.
