Cardiovascular Flashcards
When do you give abx ppx for dental procedures? What do you give?
prosthetic valves
prior endocarditis
heart txp
severe or repaired congenital heart defects
what distinguises centrals (heart) vs peripheral cyanosis
central/heart = blue mucous membranes
what are 4 characteristics that make a murmmur pathologic
symptomatic
> grade III
diastolic
continuous
clicks = pahologic mumur?
no
main diff between early onset and late onset cyanosis
early = R to L shunts late = L to R shunts
Drugs that keep PDA patent vs closed
patent = PDE1 close = indothemacin
thrombocytopenia + bilaterial absent radii, look for what heart defect?
ASD
MC congenital heart disease?
VSD
murmur of VSD?
holosystolic blowing
how long to wait until get surgical closure of PDA
1 month
what is elsenmenger syndorme?
pulm HTN reverses L to R shunts to R to L shunts
What are the 4 CHD that cause of early onset cyanosis?
- tricuspid atresia
- transposition of the great vessels
- tetrology of fallot
- TAPVR (total anomalous pulmonary venous return)
find tricuspid atreasia, next step after birth?
give PGE1 to keep PDA open then get surgury
egg on a string on CXR
transposition of great vessels
CXR with diffuse reticular pattern in cyanoic newborn
TAPVR
4 components of TOF
- pulmonic stenosis (determines prognosis)
- RVH
- overridign aorta
- VSD
what is ebstein anomaly? what is it assc with?
RA hypertrophy with atrialized RV and tricuspif valve dilation
seen in babies whose mom was on Li
trauma to hed/neck with stroke like presentation, Dx and next step
carotid artery disseaction, get MRI
what infection classically causes myocarditis?
coxsackie B
presentation of myocarditis
fever + lethargy + CHF
MC restrictive cardiomyopathy in kids
endocardial fibroelastosis
sore throat –> arthritis, erythema marginatum, choream subcut nodules
rheumatic fever
tx for rheumatic fever
amoxicillin + PO steroids
what is postpericardiotomy syndrome?
pericardial effusion (with possible tamponade) s/p cardiac surgury
tx WPW
radiofrequency ablation
pathophys of WPW
accessory tract
Tx for prolonged QT/torsades
IV mag
prolonged QT + deafness =
jervell-lang-nielsen syndrome
wide QRS + ingestion, what was ingested? Tx?
TCAs (imipramine, amitriptyline)
give sodium bicarb
syncope w/ upright Posture, Precipitating event causing intense emotion, Prodrome of dizziness or light-headedness, Pallor, no Palpitations, no Postictal sx
Dx? How to Dx? Tx?
neurocardiogenic syncope
Dx with tilt table testing
Tx: adequate hydration
