    Video Sequences

    Video Clip 1
    Figure 1: Normal exercise echocardiogram including parasternal (1a), apical 4- and 2-chamber (1b) and apical long axis views (1c).  Resting images (left) are compared with post-stress images (left). All segments show augmentation of wall motion and thickening and there is a reduction of LV volume and increment of ejection fraction with stress. Parasternal images are of excellent quality. Although the apical images are of imperfect quality, these are still sufficient for interpretation.

    Figure 2: Exercise echocardiogram (same orientation as figure 1) showing inducible wall motion abnormality in the distal anterior and lateral walls. The parasternal images show no evidence of ischemia in the posterior wall, making the changes more likely due to diagonal than circumflex vessel disease.

    Figure 4: Loss of contractile reserve in the presence of severe valvular regurgitation and normal resting function. The LV volumes after stress (right) are larger than at rest. As end-diastolic volume increases less than end-systolic volume, this corresponds to a decrement in ejection fraction, signifying decompensation of LV function with stress.
