Describe the effect of Acute MR on the left atrium and ventricle |
|
Definition
Left atrium Increased LA vol lead to increased LA pressure to prevent reguritation, this pressure is transmitted bdack to the pulmonary cirulation resulting in pulmonary congestion & edema Left ventricle Increasing sarcomere stretch to accommodate increase in volume, this results in increase LV volume and decrease AL |
|
|
Term
What happens in chronic compensated MR |
|
Definition
left ventricle gets bigger |
|
|
Term
Describe the effects of Chronic compensated MR on the left atrium |
|
Definition
the left atrium increases in size & compliance to lessen the effects of reguritation on pulmonary circulation this leads to near normal LA & pulmonary pressure but low CO |
|
|
Term
Describe the effects of Chronic compensated MR on the left ventricle |
|
Definition
Hypertrophy leads to increase in diastolic volume at low P and increase CO to near normal levels |
|
|
Term
What happens in Chronic decompensated MR |
|
Definition
Left ventricle can no longer push blood foward and LA cannot strech so you get decline in CO and signs of HF |
|
|
Term

|
Term
What's the pathphysiology in Aortic Stenosis |
|
Definition

|
|
Term
Describe the LV compensation in aortic stenosis |
|
Definition
1. Decreased compliance (LA hypertrophy) 2. Angina 3. Decrease coronary blood flow |

|
Definition
1. Degenerative aortic dilation 2. Cystic medial necrosis 3. Aortic dissection |
|
|
Term
Describe the pathophysiology of Acute Aortic regurgitation |
|
Definition
Left Ventricle Pressure rises transmitting P to the LA & pulmonary circulation this leads to dyspnea, pulmonary edemia & decrease CO |
|
|
Term
what's the pathophysiology was Chronic Aortic Regurgitation |
|
Definition
LV undergoes compensatory adaptation increasing LV end diastolic Pressure and LV hypertrophy |
