systole when the valve is closed

Question 36

When looking at m-mode, how do we know there is MV prolapse?

Answer 36

bowing of the leaflet (not-mirror image)

at the commissural edges

Question 39

What is the mitral valve B notch?

Answer 39

When the MV doesn't close. Indicates elevated LV end diastolic pressure. LV dilated

Question 40

What indicates HOCM

Answer 40

Asymmetric septal hypertrophy (ASH), Mid systolic closure of the aortic valve, and systolic anterior motion of the MV (SAM)

Question 41

What is HOCM?

Answer 41

Hypertrophic obstructive cardiomyopathy. When the LA pressure is lower than the LV pressure. Pulls the AMVL into the outflow tract
