Figure 3 Representative tissue Doppler imaging (TDI) tracing from akinetic anterior segments in two patients with large anterior infarction, one with marked recovery of segmental shortening at follow-up (P1) and one without significant improvement (P2). In P1, presence of the positive preejection velocity (+VIC) (arrow) in reperfused anterior segments was predictive of a recovery of contractile function at follow-up. In P2, absence of +VIC indicated nonrecovery despite revascularization. A large negative wave can be seen suggesting paradoxical outward bulging of this segment during preejection and early ejection.
