[Reversible left ventricular dysfunction manifesting as hyperkinesis of the basal and the apical areas with akinesis of the mid portion: a case report].
A 60-year-old man underwent emergent cardiac catheterization because of anterior chest oppression. He had been treated with calcium antagonist and nitrate. Coronary angiography showed no organic stenosis. However, left ventriculography revealed that the basal and the apical areas were hyperkinetic and the mid portion was akinetic. Echocardiography showed that the bizarre-shaped left ventricular dysfunction had completely recovered after a week. Serial electrocardiography demonstrated initial ST-segment elevation in the precordial leads followed by T-wave inversion in II, III, a VF and V4-V6. Coronary artery spasm provocation tests were negative. Endomyocardial biopsy revealed focal myocardial depletion and mild fibrosis. The present case may be an atypical form of tako-tsubo-like left ventricular dysfunction in which the left ventricular contraction is symmetric with both hyperkinetic and akinetic areas.
