IVC is larger, and more “flat”
Coronary Sinus is smaller and angled more vertical “up” on the screen

What % of CPB circ failure is due to RV failure?
20%
Why doesn’t retrograde cardioplegia protect the Right heart well?
- Right heart drains into Thebesian Veins, which drain into the right ventricle (Not into the coronary sinus)
- When ice is placed on the heart, doesn’t cool the right heart as much
- Air shoots down the RCA is air embolism occurs
What % of patients have severe refractory RV failure in:
- Cardiotomy?
- Heart Transplantation?
- LVAD?
0.1% cardiotomy
2-3% of heart transplantation
20-30% of patients receiving LVAD
Mechanically, how does an LVAD make RV function worse?
LVAD sucks the septum towards the device and the septum no longer participates in RV contraction
How does an IABP cause RV dysfunction?
IABP Causes decrease in RV afterload
Due to RV afterload reduction, septum shifts toward LV
RV can then not help as much participate in contraction

Resistance = Low

TAPSE doesn’t stratify low normal vs. normal
What is the normal value for IVA?
IVA = Isovolumetric Acceleration
1.4 +/- 0.5 m/s2

How does your eccentricity index change with worsening RV failure?
A > B as the RV turns into a “D” shape and your eccentricity index will rise

What will you see in isolated pressure overload of the RV?
- Paradoxical Septal Motion
- Late systolic Septum –> Left
- RVH = Thickness > 5mm

How do you differentiate between isolated pressure overload vs. isolated volume overload in regard to septal shifting of the RV?
Volume Overload = Max septal shift in late diastole
Pressure overload = Max septal shift in late systole
What is apex forming?
When the RV forms the apex image of the heart, you have RV dysfunction
(Normal = LV forms your apex)

What will you see during pulmonary embolism on the mid-esophageal 4 chamber?
What is this called?
Apex of the RV moves, but the base of the RV doesn’t move?
