|
|
List the etiology of TS: |
Rheumatic (*)-tethered leaflet Congenital- Carcinoid- fixed body leaflet
|
|
|
What are the physical signs of TS: |
Diastolic murmur that varies with respiration Symptoms of RV failure (ascites, peripheral edema)
|
|
|
What affect does TS have on the Atria? |
typically no affect unless mod/severe |
|
|
What is the effect on Atria when mod/severe TS is present? |
increase RA pressure causes RA dilation |
|
|
What else does the increase in RA pressure cause? |
Peripheral edema
and pressure in IVC gets backed up |
