Flashcards in MITRAL AND TRICUSPID VALVE DISEASE Deck (28):
dual-flap in the heart that lies between the left atrium (LA) and the left ventricle (LV).
mitral valve anatomy
The mitral valve ____ during diastole
opens, allows blood from A to V
The mitral valve _____ during systole
prevents regurg from LV to LA
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
Mitral valve stenosis leads to
increased pulm vasc, pressure, LA pressure, and right heart pressure
Most cases of Mitral valve stenosis are?
Acute Rheumatic fever
caused by group a strep
inflamtion involves heart, skin, and connective tissue
may lead to Mitral valve stenosis
Mitral valve stenosis presentation
-dyspnea (pulm edema)
-Hemoptysis (lung vessel rupture)
-R side heart failure
Mitral valve stenosis will show
Left atrial enlargement
Mitral valve stenosis Rx
Beta Blocker (slow)
Anti-coag (stroke risk)
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
Do patients with Mitral valve stenosis usually have rheumatic fever first?
No, but rheumatic is the most common form
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 can be caused by abnormalities of:
(any mitral anatomy)
etiology of mitral regurgitation
mitral valve prolapse
ischemic heart disease
rheumatic valve disease
LV enlargement (stretches out the valve)
the leaflets of the mitral valve bulge (prolapse) upward or back into the left atrium as the heart contracts.
Mitral valve prolapse
Mitral valve prolapse is usually
INDICATIONS FOR INTERVENTION IN MITRAL STENOSIS
– Atrial fib
– Pulmonary hypertension
mitral stenosis on PE
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.
Tricuspid valve has ___ leaflets
Tricuspid valve regurg
increased RA pressure
Tricuspid valve regurg causes
"functional" like increased volume or pressure (like pulm HTN)
Tricuspid valve regurg PE findings
Tricuspid valve regurg s/s
fatigue (dec. CO)
Tricuspid valve regurg Rx
treat the underlying cause
surgery (rare for CHF usually)
