In this section we will
learn about the effect of mitral stenosis, mitral regurgitation, aortic
stenosis and cardiac failure on aortic regurgitation.
Effect
of mitral stenosis on AR
1. Mitral
stenosis will decrease the symptoms of AR
2. There is
decrease in length and intensity of early diastolic murmur of AR and masking
of peripheral signs of aortic regurgitation.
3. There is
increased chance for
·
Atrial fibrillation
·
Pulmonary artery hypertension
4. Due to
co-existent MS – There will be loud S1 and opening snap.
What is the effect of MR on AR
Mitral regurgitation will decrease the
symptoms of AR. It will decrease the length and intensity of EDM of AR and
mask the peripheral signs of AR. Due to the coexisting mitral regurgitation
there is increased chance for atrial fibrillation and pulmonary artery
hypertension.
What is the effect of aortic stenosis on
aortic regurgitation
If the patient has coexisting AS or AR
pulse character and pulse pressure may be normal. There will be increased
length and intensity of ejection systolic murmur.
What are the effect of cardiac failure on AR
If the patient has coexisting AS or AR pulse character and pulse pressure may be normal. There will be increased length and intensity of ejection systolic murmur.
What are the effect of cardiac failure on AR
In patients with
cardiac failure pulse volume decrease and pulse pressure decreases. Early
diastolic murmur will become softer and shorter. Ejection systolic murmur and
mid diastolic murmur disappears.
