Figure 1. (a) Right anterior oblique (RAO) view of contrast left ventriculography at peak diastole demonstrates a small diastolic out-pouching of contrast material at the left ventricular inferior/medial wall (dotted arrow). (b) RAO view of contrast left ventriculography at peak systole demonstrates almost complete collapse of the previously denoted small diastolic out-pouching of contrast material at the left ventricular inferior/medial wall (dotted arrow).
