Valvular heart disease Flashcards
Stenosis leads to what kind of hypertrophy?
Concentric
In concentric hypertrophy, do the myocytes multiply in series or parallel?
Parallel
Regurgitation leads to what kind of hypertrophy?
Eccentric
In eccentric hypertrophy, do the myocytes multiply in series or parallel?
Series
Normal thickness of IV septum?
1 cm
Acute vs. chronic regurg.. In this type, you have a loud murmur with no hypertrophy
Acute
What two parameters determine the severity of stenotic lesions?
Gradient, CO
What two parameters determine severity of stenotic lesions?
Gradient, CO
One more time.. What two parameters are gonna tell you about the stenosis?
Gradient (pressure difference between two chambers) and CO
Most common cause of mitral stenosis?
Rheumatic fever
What heart sounds are you gonna hear in mitral stenosis?
Loud S1; diastolic rumble
What kind of heart sounds are you gonna hear in mitral regurg?
Systolic murmur
The most common cause of mitral regurg is progression from MVP. What replaces the leaflets in MVP?
Myxomatous tissue
Which valve disorder has a murmur that sounds like someone clearing their throat on systole?
Aortic stenosis
With aortic stenosis, you are gonna get pulsus tardus and pulsus parvus. What does that mean?
Delayed and weakened arterial pulse
Symptoms of aortic stenosis?
SAD: syncope, angina, dyspnea
What happens to the preload in aortic regurg?
Increases
What happens to the pulse pressure in aortic regurg?
Gets wider
Big sign of aortic regurg?
Bounding pulse with head bobbing
2 requirements for IE?
Bacteremia, diseased valve
MV vegetation can lead to?
stroke
TV vegetation can lead to?
pulmonary embolism
If you have diseased valve, what should you do before you see the dentist?
Take an antibiotic prophylaxis
