Quantitative analysis of tissue Doppler data is essential for assessing myocardial velocity gradients and regional contraction, which cannot be adequately evaluated by visual qualitative analysis alone.
Answers are grounded in this paper and cite their sources.
May warrant quantitative tissue Doppler over visual analysis for regional contraction; leaves open prospective validation before practice change.
A visual qualitative analysis of color Doppler myocardial images cannot show the low velocity changes in myocardial walls, and a quantitative analysis of tissue Doppler data is mandatory for an analysis of color Doppler myocardial recordings, including an assessment of myocardial velocity gradient across the thickness of the wall. Measurement of myocardial velocity in each pixel should provide access to a broader pathophysiological insight into regional contraction across wall thickness and into all myocardial segments throughout the cardiac cycle.
