Flashcards in Valvular PrOblems Deck (24):
1

systolic

120 mm Hg

2

diastolic

80 mm Hg

3

peak atrial pressure

15 mm Hg

4

SYSTOLIC MURMUR

- aortic stenosis
- mitral insufficiency

5

DIASTOLIC MURMUR

- mitral stenosis
- aortic insufficiency

6

stethoscope

- screening tool for murmur
- investigation ventricular pressure tracing

7

pressure changes occur

ventricle
atrium

8

ventricular

- peak ventricular pressure>120 mm Hg aortic valve pathology

9

aortic valve pathology

- pressure gradient between peak ventricular pressure and aortic pressure
- is caused by obstruction
- causing aortic stenosis

10

aortic valve pathology

- no pressure gradient involved
- regurgitation is taking place
- causing atrial insufficiency

11

atrial pressure >15mm Hg

- mitral valve pathology

12

mitral valve pathology

- increase in diastole- obstruction of the mitral valve, causing mitral stenosis
- increase in systole- regurgitation, mitral insufficiency

13

aortic stenosis

- obstruction of aortic valve
- peak ventricular pressure gradient of 160 mm Hg
- systolic murmur

14

aortic insufficiency/regurgitation

- peak ventricular pressure 160 mm Hg
- aortic valve
- pressure gradient between the peak aortic pressure and ventricular pressure-NONE

15

MITRAL STENOSIS

- peak ventricular pressure normal rule out aortic valve
- INCREASE ATRIAL PRESSURE and falling during systole
- DIAGNOSTIC OF MITRAL VALVE PATHOLOGY
- pressure is INCREASE IN DIASTOLE>15 mm Hg
- obstruction of mitral valve
- LEFT ventricular volume will shift to the LEFT
- impaired filling to the ventricle causing DECREASE IN EDV
- DECREASE pressure

16

mitral insufficiency/regurgitation

- normal peak ventricular pressure RULE OUT AORTIC VALVE
- atrial pressure > 30 mm Hg (normal 15 mm Hg)
- mitral pathology
- pressure is INCREASE IN SYSTOLE
- causing regurgitation of the mitral valve causing mitral insufficiency

17

S1

- mitral valve closes
- first heart sound
- isovolumetric contraction

18

S2

- aortic valve closes
- second heart sound

19

SYSTOLIC MURMURS between S1 and S2
ejection murmur

- aortic stenosis
- pulmonic stenosis
- crescendic-decrescendic
- increase then decrease in intensity

20

SYSTOLIC MURMURS between S1 and S2
pansystolic murmurs

- mitral regurgitation
- tricuspid regurgitation

21

SYSTOLIC MURMURS between S1 and S2
late systolic murmur

- mitral valve prolapse
- common in young women
- late systolic click

22

DIASTOLIC MURMUR

- between S2 and S1

23

DIASTOLIC MURMUR
early aortic and pulmonic regurgitation

- intensity that decrease in early diastole

24

DIASTOLIC MURMUR
mid to late: mitral stenosis and tricuspid stenosis

- decrease in intensity in mid to late diastolic interval
