Abstract/OtherAbstract:
Transient apical ballooning syndrome or Takotsubo cardiomyopathy (TC) is a novel acute cardiac syndrome, characterized by regional systolic dysfunction involving the apex and mid-ventricular segments, with hyperkinesis of the basal segments. Mid-ventricular ballooning cardiomyopathy (MVBC) is a recently recognized variant of TC. Both disorders share the same precipitating factors, clinical features and course; however, unlike TC, MVBC is characterized by ballooning and akinesis of the mid-ventricular segments with hypercontractility of the basal and apical segments. While the precise pathogenetic mechanism of this disorder remains elusive, microvascular dysfunction from excessive catecholamine release has been implicated. We report findings on regional contractile dysfunction (strain imaging), myocardial blood flow (semi-quantitative), and perfusion kinetics using myocardial contrast echocardiography in a series of three illustrative cases of TC.
