Flashcards in MITRAL AND TRICUSPID VALVE DISEASE Deck (28):
1

dual-flap in the heart that lies between the left atrium (LA) and the left ventricle (LV).

mitral valve

2

mitral valve anatomy

annulus
leafletts
chordae
papillary muscle

3

The mitral valve ____ during diastole

opens, allows blood from A to V

4

The mitral valve _____ during systole

closes,
prevents regurg from LV to LA

5

a valvular heart disease characterized by the narrowing of the orifice of the mitral valve of the heart. Obstructs blood flow from LA to LV

Mitral valve stenosis

6

Mitral valve stenosis leads to

increased pulm vasc, pressure, LA pressure, and right heart pressure

7

Most cases of Mitral valve stenosis are?

Rheumatic

8

Acute Rheumatic fever

caused by group a strep
inflamtion involves heart, skin, and connective tissue
may lead to Mitral valve stenosis

9

Mitral valve stenosis presentation

-dyspnea (pulm edema)
-Hemoptysis (lung vessel rupture)
-Pulm HTN
-R side heart failure
-A-Fib
-Thrombotic event

-Loud S!

10

Mitral valve stenosis will show

Left atrial enlargement

11

Mitral valve stenosis Rx

Beta Blocker (slow)
Diuretics (CHF)
Anti-coag (stroke risk)
Valve replacement

12

a non-surgical procedure performed in the cardiac catheterization laboratory.

catheters placed into blood vessels in the groin and guided into the chambers of the heart.

The catheter is positioned so the balloon tip is directly inside the narrowed valve.

The balloon is inflated and deflated several times to widen the valve opening.

percutaneous balloon mitral valvuloplasty

13

Do patients with Mitral valve stenosis usually have rheumatic fever first?

No, but rheumatic is the most common form

14

disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood--> abnormal leaking of blood backwards from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts

mitral regurgitation

15

mitral regurgitation can be caused by abnormalities of:

annulus
leafletts
chordae
papillary muscle

(any mitral anatomy)

16

etiology of mitral regurgitation

mitral valve prolapse
ischemic heart disease
endocarditis
rheumatic valve disease
LV enlargement (stretches out the valve)

17

the leaflets of the mitral valve bulge (prolapse) upward or back into the left atrium as the heart contracts.

Mitral valve prolapse

18

Mitral valve prolapse is usually

asymptomatic
good prognosis

19

INDICATIONS FOR INTERVENTION IN MITRAL STENOSIS

– Symptoms
– Atrial fib
– Pulmonary hypertension

20

mitral stenosis on PE

-Load S1
-opening snap
-diastolic rumble

21

Tricuspid valve

on the right dorsal side of the mammalian heart, between the right atrium and the right ventricle. The function of the valve is to prevent back flow of blood into the right atrium.

22

Tricuspid valve has ___ leaflets

3

23

Tricuspid valve regurg

increased RA pressure
edema

24

Tricuspid valve regurg causes

"functional" like increased volume or pressure (like pulm HTN)

25

Tricuspid valve regurg PE findings

JVD
hepatomegaly

26

Tricuspid valve regurg s/s

fatigue (dec. CO)
Ab fullness
edema
palpitations
atrial stretch

27

Tricuspid valve regurg Rx

treat the underlying cause
Diuretics
surgery (rare for CHF usually)

28

Tricuspid valve stenosis

very rare
from rheumatic heart disease
s/s: dyspnea, edema
rx: diuretics, surgery
