What is cyanosis?
A blue, gray, or dark purple discolouration of the mucous membranes caused by low oxygen (Severe hypoxia)
What is cyanosis caused by? 2
- Oxygenated blood mixing with unoxygenated blood
- Blood with low oxygen levels circulating to the body
What are S/S of cyanosis CHD? 9
- Cyanosis of lips, toes, fingers, Tips of nose

What is Truncus arteriosus?
Single large vessel arising from the base of the heart
What does this single large vessel of Truncus arteriosus supply?
The coronary, pulmonary, and systemic circulation
What are some findings of Truncus arteriosus? 3
- Large VSD
- Large common artery (As and PA)
- PFO
With Truncus arteriosus, the common trunk with a single semilunar valves arises from the heart, do what?
Overrides the VSD
The common valve may have how many cusps?
1-6
What are some things that arise from the single trunk of the Truncus arteriosus? 3
- Coronary arteries
- Main pulmonary artery
- Aortic arch
What is the incidence rate of complete transposition of the great vessels between men and women?
3:1 incidence
What is another way to refer to Complete transposition of the great arteries ?
D-TGA
With D-tga, the Ao and the PA arises from which ventricles?
- The morphological RV
- Morphological LV
Where in relation is the Ao and the PA to each other? (D-TGA)
They are parallel
What are some things that we would see with D-TGA? 3
- PFO/ASD
- Transposed PA and Ao
- PDA
What are important things to remember about D-TGA? 3
- Vessels run parallel
- Shunt dependent
- Fatal if not corrected
What are some echo features to know about D-TGA? 2
- AV anterior + to the RT of MPA
- Both seen in SAX in PSAX view and LAX in PLAX view
In terms of D-TGA, Conal ridges grow how?
In parallel rather than spiral fashion inside the Truncus arteriosus
In terms of D-TGA, the anterior aortic valve connects where?
The right ventricle
In terms of D-TGA, the posterior pulmonic valve connects to what?
The left ventricle
