Flashcards in  Heart Disease in Children Deck (14):
What causes Murmurs?
Turbulence of blood flow from high pressure chamber to low pressure chamber
Are there such a thing as innocent murmurs in children?
Yes, present in 40-60% of children and may not go away with age
What causes the innocent murmurs in neonates?
1. Closing Ductus Arteriosus
2. Pulmonic Flow
3. Tricuspid Regurgitation
Why is the main Pulmonary Artery large?
It used to be connected to the ductus arteriosus
Describe: Vibratory Still's Murmur
2-7 Years Old
Grade 1-2/6 Vibratory, Twanging, Honky, Groaning Systolic Murmur
Where can you hear Vibratory Still's Murmur the Loudest?
Loudest 3rd ICS, between LLSB and Apex
When in doubt, what kind of a murmur is it?
Differentiate Stenosis vs. Atresia
Stenosis: Obstructed but with forward flow
Atresia: No forward flow at all; structure may not have "opened up" at all
If your cyanosis lasts 6 months what do you get?
What are the values for a Hyperoxia Test if you have Cyanotic Heart Disease?
What if it's not a cardiac cause?
CHD: < 150 mmHg
Non-Cardiac: > 150 mmHg
Mechanisms of Cardiac Cyanossi
1. Decreased pulmonary blood flow
2. Right to left blood flow through a shunt lesion
3. Cardiac chamber / Structure discordance
4. Low Cardiac Output
Is chest pain in young children a problem?
No, it is usually benign
