Abstract
In patients with severe chronic multivessel disease and left ventricular dy sfunction, tissue Doppler echocardiography could distinguish viable from no nviable segments on the basis of transmural velocities and endocardium midv elocity gradient calculated at rest and with low-dose dobutamine. An unusua l bell-shaped myocardial velocity gradient pattern, characterized by promin ent midvelocities increasing with dobutamine, featured viable segments.
