Flashcards in [5] Heart Disease in Children Deck (14):
1

What causes Murmurs?

Turbulence of blood flow from high pressure chamber to low pressure chamber

2

Are there such a thing as innocent murmurs in children?

Yes, present in 40-60% of children and may not go away with age

3

What causes the innocent murmurs in neonates?

1. Closing Ductus Arteriosus
2. Pulmonic Flow
3. Tricuspid Regurgitation

4

Why is the main Pulmonary Artery large?

It used to be connected to the ductus arteriosus

5

Describe: Vibratory Still's Murmur

2-7 Years Old
Grade 1-2/6 Vibratory, Twanging, Honky, Groaning Systolic Murmur

6

Where can you hear Vibratory Still's Murmur the Loudest?

Loudest 3rd ICS, between LLSB and Apex

7

When in doubt, what kind of a murmur is it?

Systolic

8

Differentiate Stenosis vs. Atresia

Stenosis: Obstructed but with forward flow

Atresia: No forward flow at all; structure may not have "opened up" at all

9

If your cyanosis lasts 6 months what do you get?

Clubbing

10

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

11

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

12

Is chest pain in young children a problem?

No, it is usually benign

13

Top Causes of Chest Pain in Children

Idiopathic (21%)
Musculoskeletal (16%)
Cough (10%)
Costochondritis (9%)
Cardiac (4%)

14
