MV (Mitral Valve)

Denition for the Mitral Valve

D: end of systolic, immediately before the opening of the Mitral Valve

E: the arterial leaet of the Mitral valve open, it peaks at E

F: lowest point of the initial diastolic closing

A: In atrial systole, blood is propelled through the Mitral orice and the Mitral leaets

reopen the peak of this phase of Mitral valve motion is indicated as A

C: complete closure occurs after the onset of ventricular systole

A-C interval (unit : msec)

The distance between the A point and the C point

Mitral Valve D-E Excursion (unit : cm)

Distance between the onset of the opening of the Mitral valve at D and the maximum

opening of the anterior Mitral valve leaet at E

Mitral Valve D-E Slope (unit : cm/sec)

Automatically calculated from the D-E excursion the rate of change that exists

between two point(D, E)

Mitral Valve E-F Slope (unit : cm/sec)

The rate of change that exists between two point(E, F)

EPSS ( Mitral Valve E Point Septal Separation ) ( unit : cm)

Distance between the Mitral Valve E point and posterior edge of the interventricular septum

at the same point in time

Ao/LA

Aortic Root Diameter (unit:cm) : Ao Root Dia.

The distance between the leading echo of the anterior aortic wall and the leading echo of

the posterior aortic wall at R wave of the electrocardiogram

Aortic Valve Cusp Separation (Ao Cusp Sep.)

The distance between the trailing echo of the anterior aortic valve leaet and the leading

echo of the posterior aortic valve leaet in early diastole

Left Atrial Diameter (unit:cm) : LA Dia.

The distance between the trailing edge of the posterior aortic wall echo and the leading

edge of the posterior left atrial wall echo at the level of aortic wall at the R wave of the

electrocardiogram.
