Key result
Tissue Doppler imaging (E/Em ratio) was a highly sensitive (82%) and specific (94%) predictor of left ventricular end-diastolic pressure, outperforming conventional Doppler (E/A ratio).
Why the study?
Does tissue Doppler imaging (E/Em) accurately predict left ventricular end diastolic pressure compared to conventional Doppler and catheterization in patients referred for left heart catheterization?

Tissue Doppler imaging (E/Em ratio) is a highly sensitive and specific non-invasive predictor of left ventricular filling pressure, outperforming conventional Doppler.
Parvathaneni et al. (2013) conducted an observational in Left ventricular diastolic dysfunction (n=100). Tissue Doppler imaging (E/Em ratio) vs. Conventional Doppler (E/A ratio) and catheterization (LVEDP) was evaluated on Correlation between E/Em and LVEDP (p=<0.0001). Tissue Doppler imaging (E/Em ratio) was a highly sensitive (82%) and specific (94%) predictor of left ventricular end-diastolic pressure, outperforming conventional Doppler (E/A ratio).
