Peds Cardio Flashcards
What are the 3 “innocent” murmors?
Systolic, musical
- Stills murmur (systolic)
- Venous hum (continuous)
- Peripheral pulmonary stenosis (systolic)
What are the 3 pathological heart murmurs?
- Systolic
- Diastolic
- Continuous
Eval murmur by radiation…
Neck > _____
Back > _____
Axilla > ______
Neck > Aortic Stenosis
Back > Pulm valve stenosis
Axilla > Peripheral Pulmonary Murmur
Does the following describe an innocent or pathological murmur?
- Systolic
- Musical
- Not assoc. w/ adventitious sounds (S3 or S4)
- No assoc. sxs/findings
- Louder with stress
Innocent
Does the following describe an innocent or pathological murmur?
- Diastolic or continuous
- Harsh
- Clicks or S3/S4
- h/o syncope
Pathologic
Does the intensity of a HCM murmur increase or decrease during standing/valsalva?
Increase
Does the intensity of an innocent heart murmur increase or decrease during valsalva?
decrease
Does the intensity of a mitral valve prolapse murmur increase or decrease during standing?
Increase
Does the intensity of an Aortic Stenosis murmur increase or decrease during standing?
Decrease
What is the most common innocent heart murmur?
Still’s Murmur
Which murmur?
- 3-6 y/o
- Normal EKG
- low freq, vibratory, musical sound
-
Loudest in supine and stress (fevers)
*
Still’s murmur
When is the Still’s Murmur loudest? when does it change intensity?
- Loudest in supine and stress (fevers)
- Changes intensity w/ sitting position
Do you need an echo for a Still’s Murmur? Why?
No. They outgrow it in adolescent years
Which murmur?
- 3-6y/o
- Turubulence due to jugular venous drainage
- Continuous (R>L), base of heart, Diastolic louder than systolic
Venous Hum Murmur
When is a venous hum murmur loudest? Whe is it decreased (2)?
- Loudest- upright position
- Decreased w/ supine or turning neck
Is an echo needed for a Venous Hum Murmur?
No
What is the MC congenital abnormality causing morbidity and mortality in the 1st year of life in the US?
Congenital Heart Defects
Peripheral or central cyanosis?
- Low saturations and PaO2?
Central cyanosis
(these would be normal in peripheral cyanosis)
T/F: Peripheral cyanosis is normal transitional newborn physiology
True
Does acrocyanosis have normal or abnormal pulses?
normal pulses
(blue baby would NOT have normal pulses)
What are 3 sxs of CHD?
- Tachypnea
- Cyanosis
- “Grey Baby”
CHD sxs: what does tachypnea indicate?
L-R shunt
What is the difference b/w “blue baby” and “grey baby”
blue baby= cyanosis
grey baby= decreased or no systemic blood flow
Does the following describe a grey or blue baby?
- No pulse or capillary refill
- lactic acidosis
Grey baby
Cardiac physiology: 3 components?
- Volume overload (L-R shunt- ASD, VSD, PDA, etc)
- Pressure overload (Outflow obstruction, etc)
- Cyanotic lesion (R-L shunt, etc)
Types of CHD:
What are the 3 Acyanotic defects?
Volume issue!
- ASD
- VSD
- PDA
Types of CHD:
What are the 3 Cyanotic defects?
- TOF (Tetralogy of Fallot)
- TGA (Transposition of the Great Arteries)
- TA (Truncus Arteriosus)
Are prostaglandins required to treat Acyanotic defects?
NO
What are teh 4 sxs of L-R shunting?
- Tachypnea
- Poor feeding
- exercise intolerace
- Poor growth
(Large ASDs= asymptomatic)
RA, RV and PA can become ______ as a result of ASD
enlarged
Physical Exam findings of what?
- Precordial bulge
- Hyperdynamic precordium
ASD
If you hear the following on auscultation, which CHD is it?
- Normal S1
- Fixed split of S2
- 2-3/6 systolic ejection murmur at LUSB
- +/- diastolic “rumble” at RLSB
- DOESN’T change w/ position
ASD
Which CHD might have right axis deviation and right vent conduction delay seen on EKG?
ASD
How do you tx ASD?
- May close spontaneously in first few yrs of life
- +/- closure depending on RA/RV dilation–> Sx vs percutaneous closure
- No medical therapy
The goal of treatment for ASD is to prevent which 3 long term complications
- Pulmonary vascular disease
- Arrhythmias
- Embolic events
What’s the MC congenital heart defect?
VSD
