1

Know all the coronary arteries!!!

Left main coronary artery = LAD + Circumflex + Ramus Intermedius
LAD = LAD + Diagonals + Septal perforators
Circumflex = Obtuse Marginals +  Circ

 

Right main Coronary artery = Nodal + RCA
RCA = RCA + Acute/Rt Marginals + AVN +PDA + PL

2

Know where the artery serves on the heart

3

Know where the arteries arise for pulmonary circulation

Supply nutrients and circulation to lung tissue


The left bronchial arteries (superior & inferior) usually arise directly from the thoracic aorta.

 

The single right bronchial artery usually arises from:


-----Thoracic aorta at a common trunk with the right 3rd posterior intercostal artery
OR

---the superior bronchial artery on the left side

 

4

Know the basics about coronary circulation, especially the formulas!

Sinus of Valsalva - Coronary arteries – capillaries – Coronary Veins – Coronary Sinus
Coronary Artery Perfusion – Left vs Right ventricle timing

Coronary Perfusion Pressure = DBP – LVEDP
CaO2=  (1.34 x SaO2 x Hgb) +(0.003 x PaO2)
DaO2= C.O. x CaO2
VO2 =  C.O.(CaO2 – CvO2)     (3.5L/min or 45ml/kg/min)
Darkest Blood in the Body is in the C.S.

5

Know these number about MAP 

MAP = 1/3 SBP + 2/3 DBP= 1/3 PP + DBP= C.O. x SVR
C.O. – 4-6.5 L/min
SVR – 900-1500 dynes x sec/cm5
PVR – 50-150 dynes x sec /cm5

Hypotension and Hypertension ranges

 

6

Know the relationship between ventricular end diastolic volume and cardiac output

AKA the Frank Starling Curve

7

Know how afterload would affect the cardiac index and stroke volume

8

Know the normal LVEF, and factors can alter the EF

Normal LV Ejection Fraction = 55% to 70%
Percentage of LV reduction in size after systole
Variable
Valvular Dysfunction
Anesthesia Dysfunction
Other: LV mass, LV Fractional Shortening, Regional Wall Motion, LV Torsion, Cardiac Output and MAP and Stroke Volume

 

9

Awear of the regional wall motion abnormalities and the definition of all the different "kinesis"

10

What's the gold std for cardiac test?

stress test with EKG/Echo test

11

Here comes the money shot!

12

This is looking down to aortic valve

13

This is looking down to mitral valve

14

I think this might be the most important picture for TEE

15

Here's an easy 4 chamber view

16

A 2 chamber view

17

a long axis view

18

And the coronary perfusion for the money shot!
