We tested the hypothesis that tissue Doppler imaging (TDI)-derived assessment of positive preejection velocities (+VIC) can predict the recovery of contractile function after revascularization in 43 patients with a large recent myocardial infarction. A good quality TDI signal was obtained in 95.4 % of analyzed segments.
Sampling of all dysfunctional segments lasted 114 minutes per patient. Sensitivity and specificity of the +VIC to predict segmental recovery were 91 % and 71 %, respectively.
Assessment of +VIC by TDI echocardiography is a simple and accurate method to predict recovery of contractile function after revascularization
