Other Imaging Findings

Cardiac Catheterization

Coronary angiography usually demonstrates normal coronary arteries or mild coronary atherosclerosis. The left ventriculogram usually reveals characteristic regional wall motion abnormalities which involve the mid and usually the apical segments. There is sparing of the basal systolic function, and the wall motion abnormality extends beyond the distribution of any one single coronary artery.

Left ventriculogram during systole displaying the characteristic apical ballooning with apical motionlessness in a patient with Takotsubo cardiomyopathy.

The diagnosis is made by the pathognomic wall motion abnormalities, in which the base of the left ventricle is contracting normally or are hyperkinetic while the remainder of the left ventricle is akinetic or dyskinetic. This is accompanied by the lack of significant coronary artery disease that would explain the wall motion abnormalities.
