Implication

Supports noninvasive mitral velocity for LV assessment; leaves open prospective outcome validation before practice adoption.

Does noninvasive measurement of final anterior mitral leaflet closing velocity correlate with invasive measures of left ventricular performance in dogs and humans?

Population

18 open-chest dogs, 6 normal human subjects, and 40 patients with coronary artery disease

Intervention

Noninvasive measurement of peak final closing velocity (ds/dt) of the anterior mitral valve leaflet using echocardiography

Comparator

Invasive hemodynamic measurements including peak aortic ejection velocity (V), peak aortic acceleration (dV/dt), peak LV dp/dt, resting LVEDP, and angiographic ejection fraction

Outcome

Correlation between echocardiographic ds/dt and invasive measures of LV performancesurrogate

Final mitral valve closing velocity measured by echocardiography provides a simple, noninvasive method to assess left ventricular performance that correlates well with invasive hemodynamic parameters.
