1

Trace blood through body: RA -> superior vena cava

RA
Tricuspid valve
RV
Pulmonic valve
R or L pulm artery
Pulm arterioles
Pulm capillaries
Pulm venules
1 of 4 pulm veins
LA
Bicuspid valve
LV
Aortic valve
Aorta
Peripheral arteries --> arterioles --> capillaries --> venules --> inf/sup VC

2

If you pass a catheter from the inf vena cava into RA, where can the catheter go from there?

1. Tricuspid --> RV --> pulm art
2. SVC
3. Patent foramen ovale --> LV
4. Coronary sinus

3

What route would you take to place pacemaker wire in the RV?

Sup VC
RA
RV - wedged into trabeculae of RV apex

4

What route would you take to place pacemaker wire in the LV?

Sup VC
RA
Cornary sinus which lies behind LV

5

How can you tell the RV from LV?

RV = more trabeculae + tricuspid valve
LV = smoother + mitral valve

6

How can a clot from the legs cause stroke?

It's going to cause a PE... duh
Stroke:
- Septal defect
- Increased R sided P
= Paradoxical embolus

7

If the pt is in AFib, where is a thrombus likely to form?

No atrial contraction --> clots in atria
Increased risk for PE
**LA appendage

8

Name the associated L and R coronary arteries.

From sinus of valsalva = outpouching from aorta
L main coronary art from L coronary cusp sinus of Valsalva
- LAD
- L circumflex
R coronary art from R coronary cusp of sinus Valsalva

9

Describe the path of the LAD - what pts of the heart does this supply

Ant interventricular groove
Supplies:
- Ant septum
- Ant wall LV (largest pt of LV)

10

Describe the path of the L circumflex - what parts of the heart does this supply

Post AV groove = between LA & LV in back of heart
Supplies LV lat wall

11

Describe path of RCA - what parts of the heart does this supply?

Ant AV groove = bet RA & RV anteriorly
Supplies inf wall of LV & RV

12

Why is it difficult to bypass directly to the main circumflex art in surgery?

Coronary sinus is in post AV groove on top of main circumflex art
Branches of circumflex can easily be bypassed

13

How do you est RA pressure?

Int jugular vein catheter

14

If the P wave vector (direction of atrial depol) is abnormal, what are the possible sites of pacemaker?

Normal atrial depol = bet 0 --> +90 degrees
Abnormal means pacemaker cannot be the SA node
Other options:
- Somewhere else in atrium = ectopic atrial rhythm, atrial flutter
- AV node = junctional rhythm
- The ventricle
