what is the most common congenitial pediatric heart condition?
VSD
Ventricular septal defect
what is this?
where are the 2 locations these can occur?
2 types?
opening in the septum that separates the two ventricles
80% involve the thin membraneous septum
20% involve the muscular septum
can be isolated or compllex lesions (can be associated with other cardiac issues)
ventricular septal defect:
small “restrictive” VSD
what is this?
what is normal? what is abnormal that occurs?
2 key sxs to know?
MOST COMMON SIZE
large resistance through small hole
normal right ventircular pressure and pulmonary artery pressure
small left to right shunt (since left side of hear it high pressure and right is low pressure)
**aka no enough blood is going left to right that it increases the pressure on the right side of the heart*
SXS:
- harsh holosystolic murmur along left sternal border, present about 36 hours after birth
**think about it, there is a bunch of blood trying to fit through a tinny hole, so the whole time it is pumping you get a murmer
2. possible systolic thrill at left lower sternal border
ventricular septal defect:
mod-large ventricular SD
what happens in this?
what are 5 things that can happen that are bad as an effect?
sxs resemble?
increase the pressure in the RV and pulmonary ateries because enough blood is pumping over to increase it
can cause as a result:
- pulmonary artery Hypertension
- pulmonary vascaulr obstructive disease
- if large, LV dilation and failure
- HF in 80% of infants with large
- endocarditis
SXS:
SIGNS AND SXS OF HF!!!
ventricular septal defect:
mod-large ventricular spetal defect
2 TX options?

- echo doppler is diagnostic!!!
ventricular septal defect:
small “restrictive” VSD
3 TX OPTIONS?
TX:
- 24% CLOSE BY 18 MONTHS
- 50% BY 5 YEARS
- REGULAR FOLLOW UP WITH PERIODIC DOPPLER
what are the long term complications of ventricular septal defect?
3 key things?
1 overall change?
two outcomes?
- pulmonary arterial hypertension PAH can lead to irrersible pulmonary vascular obstructive disease PVOD
- significant PVOD leads to pulmoary vascular restistance and pulmonary artery pressure increase and can lead to shunt reversal, and right to left shunting
**think about it!!!…as more blood going from left to right the damange on the right side fo the heart and pulmonary artert increases,causing back up into the RV this creases the pressure to increase here and then flow from the highp pressure of the right ventricle to the relatively low pressure of left ventricle**
eisenmenger’s physiological complex
- leads to hypoxemia and right sided HF since this gives out and the oxygen then bypasses the lungs
atrial septal defect
what is this?
what percent of people does this occur in? why?
2 main physiology things occur? why?
a hole between the two atria in the heart
occurs in 25% of people
caused by lack of fusion leaving patent foramen ovale
physiology:
- left to right shunting from:
rt atrium more distensible than left
RV more compliant that LV
PuVR more than SVR
LA pressure higher that RA
- hemodynamic burden: from right ventricular oolume overload since more is going from the right atrium into right ventricle well tolerated for many years
atrial septal defect
what are the 4 physical findings?
what are the 2 ways this is dxed?
- hyperdyanamic RV: RV vlume increases leading to increase contraction via starling mechanism
- accentuated S1 at LLSB
3. S2 wildly split through inspiration and expiration
- Grade II-III cresendo-decresendo murmur
DX:
- EKG: afib/aflutter
- echodoppler
atrial septal
what are the three options and when are they appropriate?
- catheter closure at the ASD once sxs present
- if no sxs closure is reccomend if the Qp (pulomnary):Qs(systemic) blood flow 1.5:1 OR PAH present
- surgical closure-reccomended in pre-school or pre-adolescent years
pulmonic stenosis
what are the characteristics of the stenosis?
3 physiology (2 things it can lead to)?
difference in mid/mod to severe?
“domed shaped” stenosis with concentric hypertrophy
physiology:
a. must be reduced by 60% to be hemodynamicaly significant
b. causes RV pressure overload
c. can lead to RT ventricular overload
mild-mod: well tolerated, monitor
severe: leads to RV failure and premature death
pulmonary stenosis
1 dx?
1 tx? (qualifications)?
dx:
echo
TX:

gradient less than 25=no intervention
gradient over 75 always vulvoplasty
what is the most common cause of congenital heart disease in adults?
atrial septal defect
what are the 3 anatomical type of atrial septal defect?

- ostium primum: defect in the lower atrial septum
3. sinus venous defect: high in atrial septum
explain the course of atrial septal defect throughout a persons life?
5 sxs
- MOST CHILDREN ARE ASYMPTOMATIC SO DX OFTEN MISSED IN CHILDREN
- systolic ejection murmer and sxs (fatigue, dyspnea, decreased stamina) present in 20s
- 3rd-4td decased adults become increasingly symptomatic incidence of atrial fib and flutter increase
- paradoxicl emboli can result in stroke (venous emcbolism)
- premature death and heart failure occur in adults who go untreated
in atrial septal defect, what 3 parts of the heart become enlarged? why?
RA
RV
and pulmonary artery
volume overload
since there is so much coming from the left atrium over, it effects everything after the RA this can cause pulmonary HTN to occur late in the disease
what are the 2 different pressure gradients between the right ventricle and pulmonic artery indicate?
RV to PA: 40 mmHG=mod pulm stenosis
RV to PA: 75 mmHg=severe pulm stenosis
pulmonic stenosis
3 clinical manifestations
- systolic thrill at supersternal notch
- early systolic click upper LSB
- murmer is harsh, cresendo-decresendo at upper right SB radiating towards clavicle and louder with inspiration
patent ductus arteriosus
what is this/ what two things is ths between?
when does this normally close?
what is a RF for staying open?
what are the charactersitcs of small, mod and severe?
patentcy of the vessel that normally connects the pulmonary arterial system and the aorta in the fetus, between left pulmonary artery and lower aortic arch
normally closes 2-3 days after birth
BUT
OFTEN REMAINES OPEN IN PRE-TERM BABIES
small: well tolerated
mod: elevated PAP, significant shuntin from aorta to PA
severe: AO and PA in free communication marked left to right shunting and LV dysfunction (since the left is the higher pressure system)
patent ductus arteriosus
what are the 3 PE findings of this?
- HF occurs in the first weeks of life!!!!!!

discrete narrowing of the distal segment of the aortic arch, just distal to the origina of the subclavian artery
causes:
- obstruction to outflow to the lower half of the body
- LVH from pressure backload

what are 2 things this causes?
biventricular origin of the aorta (aka the aorta isn’t in the right place)
