Answer 1: The image above shows the mitral valve in M mode taken during the PLAX view at the MV leaflet tips.
Answer 2: During early diastole, the leaflets separate widely with the maximum early diastolic motion of the anterior leaflet termed the E-point
Answer 2: During early diastole, the leaflets separate widely with the maximum early diastolic motion of the anterior leaflet termed the E-point
Answer 3: During atrial contraction, the leaflets move towards each other in mid-diastole (F-point =diastasis) and then separate again with atrial systole, thus resulting in the late diastolic peak or the A point.
Extra Credit
F Point: marks the onset of diastasis slow flow
C Point: The point where the anterior and posterior leaflets of the mitral valve come together during systole.
D Point: Mitral valve opening at the beginning of diastole
F Point: marks the onset of diastasis slow flow
C Point: The point where the anterior and posterior leaflets of the mitral valve come together during systole.
D Point: Mitral valve opening at the beginning of diastole
Answer 4: EPSS = E-point septal separation and is defined as the distance between the anterior leaflet of the mitral valve and the interventricular septum.
