[Left ventriculoplasty in a patient with suspected takotsubo cardiomyopathy followed by a left ventricular aneurysm]

Abstract

A 42-year-old woman was admitted with chest pain. Coronary angiography did not reveal any significant stenosis, but left ventriculography showed akinesis and ballooning of the apex with a hyperkinetic basal segment indicating Takotsubo cardiomyopathy. Cerebral embolism occurred after one and a half years because of a left ventricular thrombus. The apical akinesis had worsened to a left ventricular aneurysm (maximum diameter 43 mm). The left ventricle was reconstructed to avoid repeated thrombus formation and cerebral infarction despite anticoagulant therapy. A pathological assessment revealed a fibrotic myocardium, but the cause of the cardiac aneurysm remained unknown. Although the outcome of Takotsubo cardiomyopathy is relatively good, careful observation and appropriate treatment are needed considering the possibility of aggravation.
