1

Aortic Stenosis

Calcification of aortic valve cups restricts forwards flow of blood during systole; LV hypertrophy develops

2

Pulmonic Stenosis

Calcification of pulmonic valve restricts forwards flow of blood

3

Mitral Regurgitation

Stream oxblood regurgitates back into LA during systole through incompetent mitral valve. In diastole, blood passes back into LV again along with new flows; results in LV dilation and hypertrophy

4

Tricuspid Regurgitation

Black flow of blood through incompetent tricuspid valve into RA

5

Mitral Stenosis

Calcified mitral valve does not open properly, impedes forward flow oxblood int JV during diastole. Results in LA enlarged and LA pressure increased

6

Tricuspid Stenosis

Calcification of tricuspid valve impedes forward flow into RV during diastole

7

Aortic Regurgitation

Stream of blood regurgitates back through incompetent aortic valve into LV during diastole. LC dilation ad hypertrophy caused by increased LV stroke volume. Rapid ejection of large stroke volume into poorly filled aorta, then rapid run off in diastole as part of blood pushed back int LV

8

Pulmonic Regurgitation

Black flow oxblood through incompetent pulmonic valve from pulmonary artery to RV
