CARDIO-Valve Flashcards
What is blood difficulty through stenosed mitral valve from LA to LV?
Mitral Stenosis- 60% reduction in opening DX
What is MCC of mitral stenosis?
Rheumatic Fever- Women
How does mitral stenosis limit CO?
Obstruction of LV filling to valve damage⇾blood builds up into LA⇾backflow to PV⇾pulmonary restrictin and limited LV filling =DEC CO
What is result of MS?
chronically will cause RF damage⇾pulmonoary v. affect pulmonary aa.
What will precordium be like w/ MS?
Quiet apical impulse⇾less fill. Parasternal lift⇾pulmonary engorded
IF S1 mitral+tri, loud snap, and S2 is split what is DX?
Mitral Stenosis. S1- is harden valve snapping, S2 split bc Aortic+Pulmonic close, + late close of mitral valve. No S3- less fluid hitting LV. No S4 d/t LV not enlarged
Why is hand grip exercises inc murmur?
Pressure incrase to open valve. Murmur-low pitched and rumbling early in diastolic relax. Waiting to be filled, but valve slow grudgin to open
What are clinical presenstion of MS?
JVD, edema, ascites. RHF
What is indicative of MS on EKG?
Afib- no filling, blood pools. Thrombus risk. MI
What occurs when blood flows back to LA d/t floppy valve?
Mitral Regurgicaton
What would someone with CHF sx poss have recurgitatino?
Volume overload. Blood flows back to LA⇾INC vol. in LA⇾LV dialtes⇾more blood flows in LV d/t floppy valves
What are SX of mitral regurgitation?
- SOB, 2, orthopnea 3. PND 4. fatige. Cant breath d/t fluid in heart and lungs
What would an echo show with MR?
Dialated LV and hyperdyname impulse. Filling more and working hard to get BV out
What can be heard at axilla and neck in MR?
Pansystolic long murmur as blood flow back
Where is PMI located for MR?
downward and left, d/t dialated enlarged LV
Why is S1 sound not heard w/ MR?
Valves not closing. S2 and S3 split bc of extra filling and splashing on LV
If blood flows into LA what happens?
Acute MR⇾wastes SV⇾overload of LV⇾LVED inc
What is MR when LVESV is reduced?
Chronic MR⇾forward stroke dec. due to flow going back into LA
Despite LV contractlity, CO is low bc…
regurginat Vol. INC LA pressure and pulmonary congestion.
