Abstract
Takotsubo syndrome or broken-heart syndrome is a rare form of nonischemic cardiomyopathy characterized by regional systolic dysfunction of the left ventricle without evidence of coronary artery disease or acute plaque rupture. This transient impairment in myocardial contractility leads to symptoms and signs that can mimic a myocardial infarction. We present a case of Takotsubo syndrome in a 47-year-old premenopausal woman with complex congenital heart disease who initially presented with acute onset of shortness of breath and chest tightness after a verbal altercation. Extremely rare cases of Takotsubo syndrome have been described in the congenital heart disease population in premenopausal women. This case emphasizes the need to highlight acquired cardiac disease in patients with adult congenital heart disease as this cohort continues to age.
