What makes the S1 sound?
close of tricuspid/mitral
open of aortic/pulm
What makes S2 sound?
close aortic/pulm
open tricuspid/mitral
What is the difference between adult and fetal heart circulation?
foramen ovale: connects R & L atria
Ductus arteriosis: connects pulm & aorta
Umbilical vein: goes to inferior vena cava; brings O2 to baby from placenta
Umbilical arteries: brings deox blood to placenta from descending aorta
how many umbilical veins and arteries are there?
1 vein and 2 arteries
Atrial septal defect (ASD)
Cause? SS? Tx?
-hole between 2 atria (patent foramen ovale)
-L to R shunt of blood
SS: usu none until older --> fatigue
TX: surg when pulm:systolic bllod flow > 2:1
What is the most common congenital heart disease?
Ventricular septal defect (VSD)
-hole between ventricles
What is Ventricular septal defect, what do you hear on exam?
-hole between ventricles
-HARSH pansystolic murmur: goes through entire systole (obscures S2 sounds)
What is Eisenmenger's syndrome?
when R side overtakes L: blood gets pushed from L to R ventricle
-pulm gets more pressure & thickens making R vent to work harder
-so now there is blood flowing from R to L vent
Patent Ductus Arteriosus (PDA)
-what kind of murmur do you hear?
ductus arteriosis doesn't close completely
-"machinery murmur"
-bounding pulses
Coarctation of Aorta
-when does it present and how do you find this?
presents 4-10 days as ductus arteriosis closes
-narrowing of aorta
-diff BP in upper & lower body
-weak femoral pulse compared to brachial
What are the 4 characteristics of the Tetralogy of Fallot?
1. ventricle septal defect
2. pulmonary stenosis
3. hypertrophy of R ventricle
4. overriding aorta
What is the most common cyanotic congenital heart disease?
Tetralogy of Fallot
-not getting O2 from R to L shunt
What is the hallmark sign of tetra of fallot?
cyanotic spells
-relieved with squatting
What is the transposition of great vessels?
pulm artery and aorta switched positions
-cyanotic and incompatible w/life
What are the two benign murmurs?
venous hum and stills murmur
venous hum
murmur from jugular venous system (heard well in neck)
-seashell sound - soft hum
-head movement can make disappear or change sounds
Stills murmur
Most common innocent murmur of childhood
-vibratory musical murmur
-loudest when lying down
What is acute rheumatic fever?
-cause
complication of group A beta hemolytic strep (S pyogenes)
-shows up from untreated throat infection (1-4wks after)
Jones criteria
to diagnose rheumatic fever
-need 2 major or 1 major and 2 minor
MAJOR: carditis, polyarthritis (MC), syndenham chorea (snakelike movement)
-Erythema marginatum, Sub Q nodules
MINOR: previous rheum fever, polyarthralgia (MC)
-fever, labs +, prolonged PR interval on ECG
YOU ALSO NEED + STREP INFECTION
How do you diag acute rheumatic fever?
jones criteria
ASO titer (anti strep)
via Echocardiogram
Marfan's syndrome
-what it is, SS, Dx?
connective tissue disorder that is autosomal dominant
SS: long finger/toes, hypermobility/dislocate joints
-eye problems, scoliosis
Dx: arm span > ht, wrist sign
-steinberg sign (thumb in palm)
-echo
What are the risks for Marfan's syndrome?
Thoracic aortic aneurysm/dilatation
Are contact sports discouraged in those w/marfan's syndrome? Why or Why not?
YES
-it inc risk of aortic dissection from inc cardiac output
Kawasaki Disease
What? SS?
-mucocutaneous lymph node syndrome
-can lead to irreversible heart dz & death
SS: prolonged fever > 5 days, conjunctivitis (spare limbus)
-crack/fissure of lips w/inflamm of mucous membranes
-edema of hands & feet
What are labs for kawasaki disease?
thrombocytosis, inc sed/CRP
What is the Tx for kawasaki dz?
What is the Risk or complications?
IVIG (immunoglobulin)
comp: heart problems, CORONARY ARTERY ANEURYSM & possible acute MI
Hypertrophic Cardiomyopathy
-what is it? cause?
-L vent outflow obstruction from thickened septum (intraventricle)
-no blood to aorta so none to body
What are the symptoms of hypertrophic cardiomyopathy?
MC there are none
-syncope, palpitation, dizziness w/exercise
-murmur increases when coming up from a squat
