Takotsubo cardiomyopathy and coronary vasospasm during orthotopic liver transplantation: separate entities or common mechanism?

摘要

TAKOTSUBO CARDIOMYOPATHY (idiopathic or transient left ventricular apical ballooning syndrome [ABS]) is a reversible condition frequently precipitated by a stressful trigger that clinically mimics an acute ST-elevation myocardial infarction.1 Characteristically, hypokinesis or akinesis occurs in the mid and apical segments of the left ventricle in the absence of epicardial coronary lesions. Preserved (or hyperdynamic) function of the basal myocardial segments results in apical ballooning, assuming the shape of a Japanese pot used to catch octopus (a takotsubo).
