Difference between LA pressure in MS vs MR? MS - LA pressure rises during systole and diastole MR - LA pressure rises during systole only. So when patietn has significant symptoms of raised LA pressure… MS is more likely than MR
Passive elevation of PAH - due to elevation of Pulmonary VENOUS Pressure Protective and Reactive Vasoconstriction of arterioles Obliterative arteriopathy - hypertrophy of tunica media

MR - LA pressure rises during systole only.

Thank you a ton sir and Doc Hafeesh
Causes of Acute MR?
1. Ischemia
2. Infective Endocarditis
3. Iatrogenic or Trauma
4. Post BMV
Conditions
in which a MS patient becomes ASYMPTOMATIC?
1. Associated ASD
2. Development of Severe PAH
Development of RV dysfunction.
What is the effect of pregnancy on MS vs MR?
1. Increased HR - less diastolic filling
2. Increase in Blood Volume - more pulmonary congestion - more pulmonary venous congestion
3. Decrease in PVR -
Mechanisms of PAH in MS?
Passive elevation of PAH - due to elevation of Pulmonary VENOUS Pressure
Protective and Reactive Vasoconstriction of arterioles
Obliterative arteriopathy - hypertrophy of tunica media
1. Passive
2. Reactive
3. Obliterative
Hemodynamic changes of pregnancy?
Four increases
HR
Blood Volume
BP
CO
SV
One decreases
PVR
