[Tako-tsubo: a rare form of transient left ventricular dysfunction].
The authors report the case of a 67 year old caucasian female admitted for suspected acute coronary syndrome with ST segment elevation. Coronary angiography did not show any coronary lesion but ventriculography revealed akinesia of the middle and apical segments with hyperkinesia at the base. An isolated moderate elevation of troponine Ic was noted. On the 10th day the methergin test was negative and ventriculography showed complete recovery of the left ventricular segmental kinetics. Left ventricular transient apical ballooning, or tako-tsubo syndrome, is characterised by reversible akinesia of the middle and apical segments with no associated coronary lesion or enzymatic elevation concordant with the extent of the akinetic areas. It mainly affects women between 50 and 60 years old and follows emotional or physical stress. The prognosis is excellent in survivors with a rapid return of normal systolic function. The pathophysiology remains debatable, excluding myocarditis in favour of sideration.
