Cardiac catheterization. Coronary angiography revealed intact left anterior descending, circumflex (A), and right coronary arteries (B). Left ventriculography in the right anterior oblique view showed the typical features of apical ballooning (arrowhead), and basal hyperkinetics (asterisk), and an end-diastolic volume of 145 mL, an end-systolic volume of 106 mL, an ejection fraction of 27% (C and D). Left ventriculography in left anterior oblique view (E and F) showed concentric circles caused by apical ballooning (arrowhead), and basal hyperkinetics (asterisk) in systolic phase (F).
