Zusammenfassung
The ratio between early diastolic transmitral velocity (E, using pulsed Doppler) and early mitral annular diastolic velocity (Ea, using tissue Doppler imaging) (E/Ea) has been correlated with left ventricular (LV) filling pressure, but this is not relevant in all patients. We belive that combining the index of diastolic function (E/Ea) and a parameter that explores LV systolic performance (Sa, peak systolic velocity of mitral annulus) provides a close prediction of LV filling pressure. Aim: To evaluate the correlation between tissue Doppler velocities at different sites of mitral annulus and the left ventricular…
