Inverted Takotsubo Cardiomyopathy Induced by Dobutamine Stress Echocardiography with Atypical Presentation

Abstract EN

A 48-year-old woman was scheduled by our lab to perform a standard dobutamine/atropine stress echocardiogram.

During the test, the patient referred to a slight chest discomfort and developed a progressive left ventricle akinesia of all midbasal LV segments, thus mimicking a midbasal ballooning.

ECG persisted without significant abnormalities and with no raise of Troponin I.

Coronary angiography showed normal coronary arteries and ventriculography a severe EF reduction and apical hypercontractility.

Echocardiography showed a progressive improvement with a complete recovery 48 hours later.

This is a rare case of inverted takotsubo syndrome induced by dobutamine stress echocardiography that occurred with atypical presentation.
