Tissue Doppler echocardiography predicts an ejection fraction >50% with 88% sensitivity and 97% specificity when the six-site average peak systolic mitral annular velocity is >5.4 cm/sec.
Tissue Doppler echocardiography provides quantitative assessment of myocardial function, allowing for accurate estimation of ejection fraction and ventricular filling pressures, as well as differentiation between constrictive and restrictive cardiomyopathies.

TDE may refine noninvasive myocardial assessment; leaves open standardization and outcome validation before routine adoption.
John Gorcsan (2000) reported a review. Tissue Doppler echocardiography was evaluated. Tissue Doppler echocardiography predicts an ejection fraction >50% with 88% sensitivity and 97% specificity when the six-site average peak systolic mitral annular velocity is >5.4 cm/sec.
