Does anterior mitral leaflet motion on echocardiography accurately reflect transmitral blood flow in patients undergoing cardiac catheterization?
Anterior mitral leaflet motion on echocardiography can noninvasively approximate the relative velocity of transmitral flow and the percent of stroke volume entering the left ventricle.
Laiken et al. (1979) conducted an observational in Patients undergoing cardiac catheterization (n=11). Anterior mitral leaflet echogram vs. Invasive measurement of transmitral blood flow via left ventriculography was evaluated on Correlation between anterior mitral leaflet motion and transmitral blood flow. Anterior mitral leaflet motion on echocardiography closely approximated the percent of stroke volume entering the left ventricle, allowing noninvasive estimation of transmitral flow velocity.
