valve at the medial part of the anulus fibrosus, obtained by echocardiography
(EC)
Reconstructed M-mode (M42) registration.
Event lines
a'-h' added.
- a' :
Point immediately prior to atrial contraction affecting the valve plane
- b' :
Point at maximum displacement of the valve plane by atrial systole
- c':
Closing of the mitral valve
- d' :
End of the supposed isovolumetric ventricular contraction
- e' :
Point at which the valve plane has reached the same position, as prior to atrial
systole
- f' :
Amplitudinal maximum (closest approach to apex)
- g' :
End of rapid return of the valve plane, in atrial direction
- h' :
Slight rebound movement, due to overshooting
