Background: Takotsubo cardiomyopathy (TC) is defined as a temporary and
reversible systolic abnormality of the left ventricle’s apical area
resembling myocardial infarction (MI) in the nonexistence of coronary
artery disease (CAD).Only a few cases have been reported after
cardiac operations or after pericardiocentesis. Aims: To emphasize the
need to be aware of the possibility of the occurrence of this
potentially fatal complication after cardiac surgery. Materials and
methods: A-66-year old man underwent pericardiectomy.Postoperative he
endured TC and progressed exacerbation of hemodynamic
instability.finally, he had to be supported by intra-aortic balloon
pump（IABP),extracorporeal membrane oxygenation（ECMO).
Results: Patient’s left ventricle function recovered fully in two weeks.
Discussion: we discussed the pathogenesis and treatment of postoperative
TC. Conclusion:TC has to be carefully considered in differential
diagnosis in case of acute left ventricle dysfunction following cardiac
surgery. Keywords: pericardiectomy; takotsubo cardiomyopathy.
