Key result
Echocardiography of the anterior leaflet of the mitral valve correlates well with hemodynamic indicators of mitral valve opening and closure, though motion is unpredictably delayed compared to cineroentgenography.
Why the study?

Supports echocardiography for mitral timing in canine models; leaves open human validation accounting for delays.
Does the echocardiogram of the anterior leaflet of the mitral valve accurately correlate with hemodynamic and cineroentgenographic indicators of mitral valve motion in dogs?
Echocardiography of the mitral valve anterior leaflet correlates well with hemodynamic indices of opening and closure, validating its use as a noninvasive reference for timing intracardiac events.
Pohost et al. (1975) studied Dogs on right heart bypass. Echocardiogram of the anterior leaflet of the mitral valve vs. Hemodynamic and cineroentgenographic data was evaluated on Timing of mitral valve opening and closure. Echocardiography of the anterior leaflet of the mitral valve correlates well with hemodynamic indicators of mitral valve opening and closure, though motion is unpredictably delayed compared to cineroentgenography.
