PEP/TS correlations may support mitral annular intervals as LVEF surrogates in CAD; hypothesis-generating and requires prospective validation before clinical use.
Do mitral annulus time intervals measured by pulsed Doppler tissue imaging correlate with left ventricular ejection fraction in patients with coronary artery disease?
Pulsed Doppler tissue imaging of mitral annulus time intervals (PEP and TS) provides a promising quantitative index for assessing global left ventricular systolic dysfunction in patients with coronary artery disease.
