Abstract
The clinicopathologic findings of reversible ampulla-like ventriculogram of
the left ventricle were studied in 8 elderly women and one middle-aged man
. Their coronary arteriograms were normal, even in the 7 patients who had S
T elevation on electrocardiogram. Coronary spasm was positive in only 2 of
the 7 patients who received provocation rests. Biopsy specimens revealed fo
cal myocyte injury. Normal coronary arteriograms during ST elevation and th
e presence of pathologic myocardial lesions were not consistent with a conc
ept of stunned myocardium. The presence of myocardial lesions suggested tha
t focal and disseminated myocardial damage had occurred.
