Broken heart syndrome is characterized by transient left ventricular dysfunction with chest pain, electrocardiographic changes, and release of myocardial enzymes mimicking acute myocardial infarction. Physical and emotional stress usually precede the onset of symptoms. This dysfunction, known as takotsubo cardiomyopathy (TC), has been observed predominantly in women older than 60 years of age but very rarely reported in younger adults or children. Here we describe a 17-year-old girl with TC.
