Peds Final Flashcards
Still Murmur
innocent
Most common innocent murmur in YOUNG children (2-7 YO)
Still Murmur
innocent
Musical, short, high pitched, loudest LYING supine
Pulmonary Flow Murmur
innoncent
Soft, loudest supine
3YO and older
Venous Hum
innocent
Continuous musical hum, resolves when pt LYING supine
2YO and older
Venous Hum
(innocent(
Louder in diastole and sitting position w head extended
Disappears w: turning head or lying supine
Venous Hum (innocent) best heard @
Right or Left Upper Sternal Border (R/LUSB)
Still Murmur (innocent) best heard @
Left LOWER Sternal Border (LLSB)
Umbilical vein
brings oxygenated blood from placenta to fetus
Ductus Venosus
short cut from umbilical vein to IVC
Foramen Ovale
R atrium –> L atrium
Ductus Arteriosus
blood from Pulmonary Artery –> Aorta (directs blood away from the lungs)
After birth, Ductus Arteriosus:
shunting not needed
Blood flow can continue: 1-5 days
Closure by: 7-14 days
Most common congenital heart defect
VSD
VSD is associated with
Tetralogy of Fallot
Trisomy 21
Physical Exam of VSD
Harsh, holosystolic murmur at LLSB (Left LOWER sternal border)
EKG of VSD will show
Left Ventricular Hypertrophy
CXR of VSD will show
Cardiomegaly, increased Pulmonary vascular markings
Tx for VSD
May spont close
Treat CHF (diuretics)
Surgical: Septal occlusion via cardiac cath VS Surgical closure vie median sternotomy*** (preferred)
Preferred surgical tx for VSD
Surgical closure via median sternotomy
ASD
Classified by anatomic location
Ostium Secundum: most common (usually isolated defect)
Ostium Primum (assoc w other stuff)
Sinus Venosus (more rare)
ASD physical exam
Widely split S2
Rales, Respiratory retractions
Patent Ductus Arteriosus
More common in premature infants, F>M, and Maternal Rubella
Patent Ductus Arteriosus
PDA
Sx depend on age, ductus size, other abn
infant: CHF, tachy, FTT, resp distress
child: SOB, easy fatigue
adult: Eisenmenger syndrome, clubbing, cyanosis
Patent Ductus Arteriosus
PDA
Continuous MACHINERY like murmur
Wide pulse pressure
Bounding pulse
Tx for Patent Ductus Arteriosus
PDA
Keep open: Prostaglandins
Close: Endomethacin (Prostaglandin Inhibitor)
Coarctation of Aorta
Narrowing of aortic arch
Coarcation of Aorta
often seen w/ TURNER syndrome
Unexplained UE HTN
Physical Exam of Coarcation of Aorta
Absent/decreased Femoral pulse
Upper Extremity BP is 20 higher than Lower extremity
CXR of Coarcation of Aorta
“Figure 3 sign”
“Inferior Rib Notching”
Tet of Fallot
VSD
Overriding aorta
RVH
RV outflow obstruction
Most common cyanotic CHD
Tet of Fallot
Tet spells
sudden onset or worsening of cyanosis
irritable –> LOC
start 4-6 mo
toddlers may squat to increase SVR
Tet of Fallot exam
Harsh SYSTOLIC EJECTION
CXR of Tet of Fallot
Boot shaped heart
w/upturned apex
Tx for Tet of Fallot
Tet spells: oxygen, knee-chest position increases SVR
surgical repair by age 1
can also do morphine, fluids, and BB or phenylephrine
Transposition of Great Arteries (TGA)
arteries completely switched, coming off the wrong ventricle
TGA
second most cyanotic CHD
TGA presentation
VERY BLUE BABY but without respiratory distress or significant murmur
“Blue baby”
CXR of Transp of Great Arteries (TGA)
Egg on a string
CXR is non diagnostic
ECHO is diagnostic
Tx of TGA
Cardiac cath
Prostaglandin EW - keep ductus arteriosus open
SURGERY (4-7 days)
Surgery for TGA
Done at 4-7 days
switch great arteries and re-implant Coronary arteries
> 95% operative survival
Tricuspid Atresia (no tricuspid valve) BLOCKED
many other defects occur
if untreated, surv rate as low as 10% by age 1
Tricuspid atresia (blocked)
Central cyanosis @ birth
single heart sound S2
Tricuspid atresia tx
Initial: Prostaglandin E1 to keep ductus arteriosus OPEN and supportive care
THEN: surgery
Truncus Arteriosus
ONE BIG ARTERY coming from the heart
VSD always present
Truncus Arteriosus exam
Loud single S2
Narrow S2 Split
Prominent ejection click, systolic ejection murmur at LLSB
Treatment for Truncus Arteriosus
CHF tx, surgery
Total Anom Pulmonary Venous Return (TAPVR)
Pulm veins drain into venous system
oxygen rich and poor blood mix in R atrium
Presentation: severe cyanosis, resp distress, CHF
Tx for TAPVR
surgery
Hypoplastic Left Heart Syndrome
underdevelopment of L heart
Stenosis of Mitral and Aortic valves
Presentation of Hypoplastic L heart synd
mild cyanosis, but stable at birth while Ductus Arteriosus is still OPEN
rapid deterioration when it closes
Tx for Hypoplastic L heart synd
Prostaglandin E1 to keep Ductus Arteriosus OPEN ESSENTIAL
then, Staged surgeries
Conditions in which we give Prostaglandin E1 to keep Ductus Arteriosus OPEN
Hypoplastic L Heart Synd
Tricuspid Atresia
Transposition of Great Arteries
Fetal Alcohol Synd
VSD
ASD
Maternal Rubella
PDA
Pulm Stenosis
Acute Rhemuatic Fever
2-4 wks after strep throat
Diagnosis by jones criteria: 2 major or 1 major and 2 minor
Major jones criteria
for Acute Rhemuatic Fever
Pancarditis (pericarditis, endocarditis, myocarditis)
Acute Rheumatic Fever
Valvulitis (esp of Mitral 75% and Aortic valves- both on LEFT side of heart)
Tx for Acute Rheumatic Fever
ASA or corticosteriods- anti inflammatory
Abx
Heart failure management
no therapy to slow the progression of valvular damage
consider prophylactic abx if person has had this bc if they get it again, much higher risk to progress to Rhemuatic Heart Dz the next time
Kawasaki Dz
Vessel Vasculitis
Males > females
90% cases of children <5YO
