RVSF Flashcards
What are the 2 types of PHTN?
- primary - idiopathic or may be genetic
- secondary - heart or lung disease
What may we witness in PRIMARY PHTN?
increase in the smooth arterial lining
Give examples of SECONDARY PHTN?
- COPD
- sleep apnea
- pulmonary emboli
What are the SIGNS of RVSF?
- overload volume to peripheral
- decreased cardiac output
What are the symptoms of OVERLOAD VOLUME TO PERIPHERAL?
- JVD
- ascites
- hepatomegaly
- peripheral edema
What are the symptoms of DECREASED CARDIAC OUTPUT?
- SOB
- fatigue/weakness
- hypotension
What MURMUR is heard with RVSF?
Right sided murmur (S3,S4)
What is the difference of RV to LV cross sectionally?
RV is U shaped
LV is spherical
RV wraps around LV in the U shaped manner
How should a NORMAL RV appear in A4 view?
appear somewhat triangular with broad base and narrow apex
What is the difference of RV to LV in A4 view?
- RV apex is slightly closer to the base than the LV apex
- RV apex is either closer to or encompasses the LV apex
What views are preferred for RV?
A4 & subcostal
What are the ECHO FINDINGS of RVSF?
- RVH
- RVD
- paradoxic septal motion with D shaped LV
- reduced contractility
- dilated RA and IVC
- premature closure of PV
RVH is a response to what?
initial response to pressure overload from PS, primary or secondary PHT
What measurements are done in A4 RV FOCUSED? & What are the NORMS?
- Basal ≤ 4.1 cm
- Mid ≤ 3.5 cm
- Length ≤ 8.3 cm
What measurements are done for RA in A4? & What are the NORMS?
- RA Area ≤ 19 cm2
- RA Major ≤ 5.3 cm
