Takotsubo syndrome after cardiac surgery.

We have not found any reports to date of Takotsubo syndrome after cardiac surgery. Recently described Takotsubo syndrome is characterized by acute reversible left ventricular dysfunction with apical ballooning in the absence of coronary artery disease, and with chest pain and electrocardiographic changes mimicking acute anterior myocardial infarction, but with minimal release of myocardial enzymes. We describe Takotsubo syndrome that developed after elective mitral valve replacement and tricuspid annuloplasty in a 62-year-old woman. On supportive therapy with vasopressors, left ventricular function gradually improved with an ejection fraction returning to 50%. Takotsubo cardiomyopathy should be considered as a possible complication of the cardiac surgery.
