Valvular heart disease Flashcards
What are the four heart sounds?
S1
S2
S3
S4
What is the S1 heart sound?
closure of the mitral and tricuspid valve “lub”
What is the S2 heart sound?
closure of the aortic and pulmonic valve “dub”
What is the S3 heart sound?
suggests congestive heart failure
What is the S4 heart sound?
suggests poor ventricular compliance
Where should you listen for the aortic valve sounds?
right of sternal border at 2nd ICS
Where should you listen for the pulmonic valve sounds?
left of sternal border at 2nd ICS
Where should you listen for the mitral valve sounds?
left midclavicular line at 5th ICS
Where should you listen for the tricuspid valve sounds?
left of sternal border at 4th ICS
Which valvular diseases are associated with eccentric hypertrophy? (select 2)
a. mitral stenosis
b. mitral regurgitation
c. aortic stenosis
d. aortic regurgitation
b. mitral regurgitation
d. aortic regurgitation
The ____________________________ open to let blood flow from the atria to the ventricles
atrioventricular valves (mitral and tricuspid)
The ___________ open to let blood flow from the ventricles to the aorta and pulmonary artery respectively
semilunar valves (aortic and pulmonary)
Valvular stenosis is a ____________ to forward flow during systole
fixed obstruction
Stenosis results in
pressure overload–> concentric hypertrophy
Concentric hypertrophy means that the
sarcomeres are added in parallel
Valvular regurgitation occurs when the
valve is incompetent
Flow re-enters the chamber through the incompetent valve during
diastole
