Tissue Doppler imaging is a fundamental echocardiographic technique for assessing myocardial velocities, aiding in the diagnosis of subclinical dysfunction and specific cardiomyopathies.
Tissue Doppler imaging (TDI) records velocities of myocardial tissue. Routinely longitudinal velocities of medial and lateral mitral annulus and lateral tricuspid annulus are evaluated in apical four chamber view. Commonly recorded waves include isovolumic contraction wave, systolic wave, isovolumic relaxation wave, early diastolic wave, and late diastolic wave. TDI is useful in detection of subclinical systolic dysfunction and early diastolic dysfunction. It is useful in differentiating athlete's heart from hypertrophic cardiomyopathy and pericardial constriction from restrictive cardiomyopathy.
