Transient midventricular ballooning syndrome. An atypical presentation of takotsubo cardiomyopathy

Abstract

A 72-year-old woman without cardiovascular history presented with acute substernal chest pain and dyspnoea. The electrocardiogram was normal, but the blood test analyses showed an elevated troponin T level. Emergency coronary angiography revealed normal epicardial coronary arteries, but the left ventriculogram demonstrated midventricular dilatation and akinesis with well-preserved contractility of the apex and base. The patient was diagnosed as having an atypical presentation of takotsubo cardiomyopathy. She was treated with a beta blocker and an ACE inhibitor and recovered well. A follow-up echocardiogram at 2 months showed normalization of the wall motion abnormality.

Key Words:

• takotsubo cardiomyopathy
• stress cardiomyopathy
• transient ventricular ballooning.
