초록
Transient left ventricular apical ballooning syndrome is also known as takotsubo cardiomyopathy, and this is characterized by transient wall-motion abnormalities involving the left ventricular apex without significant stenosis on the coronary angiogram. We report here on a new variant of transient left ventricular ballooning in which only the mid-ventricle was affected. The patient initially presented with dyspnea and she had wall-motion abnormalities involving the mid-ventricle with hypercontractility of the apical and basal segments in the absence of a significant coronary artery stenosis. Emotional or physical stress or other preceding triggering factors might play a key role in this cardiomyopathy, but the precise etiology remains unknown. So far, the cases of this syndrome have been reported only among the North America Caucasian population and the Japanese population. (Korean J Med 74:321-324, 2008)
