RV DIMENSIONS:
1)What basal and mid RV diameter measurements classify the RV as dilated?
2) What longitudinal dimension classifies the RV as enlarged?
1) basal > 42mm
mid > 35mm
2) longitudinal > 86mm
RA DIMENSIONS:
What 1) area 2) length 3) diameter classify the RA as enlarged?
1) > 18 cm^2
2) > 53 mm
3) >44 mm
RVOT DIMENSIONS:
1) What are the upper cut-offs for RVOT measured from PSAX (distal RVOT) and PLAX (prox RVOT)?
2) What is the most accurate sight to use and why?
1) PSAX - distal >2.7cm
PLAX - prox >3.3 cm
2) Distal - just before the PV - more reproducible
RV WALL THICKNESS:
1) What is the upper cut off for RV wall thickness?
2) What can cause RVH or wall thickening?
3) Sight of measurement and why?
1) > 0.5 cm
2) PHTN - RVH
thickening - infiltrative disorders like amalyoid
3) subcostal
- better beam alignment - ax res > lat res
RV SYSTOLIC FUNCTION:
1) Name 5 ways to assess RV systolic function and there cut off values.
1) TAPSE - m-mode - <1.6 cm
2) DTI lat annulus - < 10 cm/s
3) PW MPI - > 0.4
4) DTI MPI - >0.55
5) FAC - < 35 %
RV DIASTOLIC FUNCTION:
1) How is this performed?
2) What 3 values are used as indicators of RV diastolic dysfunction.
1) PW at TV leaflet tips for tricuspid inflow
2) a; E/A <0.8 or >2.1
b; E/E' >6
c: DT <120 ms
1) Name 5 views that the RV can be assessed from.
2) Why is it important to use so many views?
1) PLAX, RV PLAX (inflow), PSAX, Ap 4C, RV focused 4C, subcostal
2) Complex morphology, cant see all structures from one view
R. HEART CORONARY SUPPLY:
1) What is the main coronary artery that supplies the RV?
2) what branch is this via?
3) What branch supplies the posterior 1/3 of the ventricular septal wall? Via what?
1) RCA
2) acute marginal branch
3) Posterior descending artery via posterior septal perforators.
4) What branch supplies the moderator band?
5) In 30% of patients the ______ _______ arises for a separate coronary ostium and supplies the ______.
4) first septal perforating branch o f the LAD CA
5) conus artery, infundibulum
6) 10% of hearts, the____________ branch of the _______ ____________ supplies a portion of the RV free wall.
7) What may supply the RV apex?
6) posterolateral, circumflex artery
7) LAD
