Also known as transient left ventricular apical ballooning syndrome or stress cardiomyopathy. One of the hallmarks of this syndrome is that the apical ballooning is transient, typically resolving in days to weeks. Takotsubo cardiomyopathy typically arises in the context of acute emotional or physical stress. It often resembles an acute coronary syndrome. The pathognomic findings are ballooning (dilatation and akinesis) of the left ventricular apex, with compensatory hyperkinesis of the basal walls of the left ventricle. Coronary angiography reveals no obstructive coronary-artery lesions; in addition, the distribution of left ventricular dysfunction often extends beyond the distribution of a single coronary artery.
