Figure 1 Four-chamber view showing an akinetic septum and apex (a) with absent contrast opacification in this region at short triggering intervals (b) but homogeneous opacification with delayed triggering (c) and normal resting function six months later (d).
Figure 2 Four-chamber view showing an akinetic septum and apex (a) with no contrast opacification in this area with early (b) or delayed (c) triggered imaging and failure of recovery of systolic function at follow-up (d).
