cardio Flashcards
normal murmur in children and pregnant women
s3
murmur ass. with increased filling pressures (HF, mitral reurg) and dilated ventricles, restrictive cardiomyopathy
s3
murmur with ventricular hypertrophy
s4
which wave of JVP is absent in afib
a wave (atrial contraction). x wave (a, c, x goes down) absent in tricuspid regurg
pulmonic stenosis, RBBB
wide split
ASD (left to right shunt). regardless of breath
fixed split
sortic stenosis, LBBB, paradoxical split. on inspiration, p2 and a2 are closer so inspiration paradoxically eliminates the split
paradoxical split
Continuous murmur at left infraclavicular region
PDA
systolic murmur at LSB
Hypertrophic Cardiomyopathy
baroreceptor firing rate
mimics BP. So ANS is checking out the baroreceptor, when the baroreceptor firing rate decreases the ANS knows the BP is also decreased
lack of aorticopulmonary septum formation (problem of neural crest cells)
Truncus arteriosus
separation of systemic and pulmonic circulation, not compatible with life without shunt
Transposition of great vessels
failure of aorticopulmonary septum to spiral
transpotion of great vessels
displacement of the infundibular septum
tetrology of fallot
tetrology of fallot
- Pulmonary stenosis (prognostic)
- RVH
- Overriding aorta
- VSD
why do you squat during tet spell
Increases systemic vascular resistance, which decreases the normal R–>L shunt and improves cyanosis (get more blood to go to lungs)
frequency of l-r shunts
VSD> ASD>PDA: blue kids use VAP’s
congenital heart disease: babies/kids cyanosis
R->L Shunts = 5 T’s. Blue babies drink from TiTTies
L->R Shunts = VSD>ASD>PDA. Blue kids hit the VAP
ASD vs PFO
both can cause paradoxical emboli (venous to systemic)
ASD: Septa are missing tissue (i.e. ostium primum defect)
Patent Foramen Ovale: failure of ostium primum and secundum to fuse
PFO is a problem of fusion
PFO is a _______ __ ________
PFO is a problem of fusion
PDA can be caused by (2)
Congenital Rubella
Neonatal Respiratory Distress Syndrome (surfactant deficiency–>alveolar collapse–>low 02)(risk increased with prematurity, maternal diabetes, c-section)
PDA/eseinmenger clinical manifestation
Lower Extremity cyanosis
Turner syndrome cardiac manifestations
Bicuspid aortic valve
coarctation of the aorta
HTN in upper extremities, delayed pulse in LE (brachial-femoral delay)
Coarctation of the aorta
notched appearance on CXR
Coarctation of the aorta
maternal diabetes cardiac manifestation
Transposition of the great vessels
indirectly to PDA because ass. with NRDS
Fetal alcohol syndrome congenital defects
All 3 VAP
Tetralogy of fallot
So it took mom 4 drinks and a VAP to give her baby FAS. Tetra + VAP
Marfan syndrome cardiac manifestations
MVP
Thoracic Aortic Aneurysm
Cystic medial necrosis of aorta: Aortic regurg and Aortic dissection
ebstein anomaly
lithium exposure (Bipolar patient)
22q11 (aka DiGeorge)
Tetralogy of Fallot, Truncus Arteriosus, Transposition of great vessels
string of beads appearance, HTN in 20-30 year old caucasian chick
Fibromuscular dysplasia
which organ is spared in Polyarteritis nodosa
LUNGS BETA. No PAN in the PULM
Hypertensive emergency
get acute end-organ damage: Papilledema, Encephalopathy, retinal hemorrhages, etc
HTN predisposes to:
afib, CAD, LVH, aortic dissection/aneurysm, CKD
Hyperlipidemia sings (3)
Xanthoma
Tendinous xanthoma (achilles)
Corneal arcus
thickening of wall via smooth muscle hyperplasia
Onion skin apperance –> Hyperplastic arteriolosclerosis
3 types of arteriosclerosis
Atherosclerosis (Intima of medium/large. cholesterol plaques)
Arteriolosclerosis (small arterioles.hyaline/hyperplastic)
Monckeberg (Media)
vascular stiffening without obstruction (intima not involved)
Monckeberg (medial calcific sclerosis)
Arteriosclerosis caused by buildup of cholesterol plaques
Atherosclerosis
who is most likely to get atherosclerosis
Men and Postmenopausal women
first step of atherosclerosis
Endothelial cell dysfunction.
increased endothelial cell permeability = LDL cholesterol into intima = phagocytosis by MQ = foam cell and VSMC from media to intima (these are all “initial step”)
what promotes migration of smooth muscles from media to intima and SMC proliferation?
PDGF and FGF
Obliterative endarteritis of the vaso vasorum
Tertiary Syphilis
diastolic decrescendo murmur
Aortic Regurg.
Aortic Regurg + mediastinal widening
Aortic Aneurysm
intimal tear vs intimal streak
tear: Aortic dissection
streak: atherosclerosis
Presentation of aortic aneurysm
lower back/abdominal pain. Abdominal AA presents as pulsatile abdominal mass
pathology: AAA vs Thoracic AA
Abdominal: transmural inflam
Thoracic: cystic medial degeneration
unequal BP in arms + severe pain
Aortic dissection (intimal tear)
CXR of aortic dissection
mediastinal widerning
arteries involved in atherosclerosis
ABDOMINAL Aorta> coronary artery>popliteal artery>carotid
marfan and ehlers danlos
cystic medial necrosis (media)
known triggers of Prinzmetal angina
Tobacco, cocaine, triptans
tx of prinzmetal
Ca channel blocker, nitrate, smoking cessation
t-wave inversion but no cardiac biomarker elevation
Unstable angina (nstemi would show increase biomarkers)
coronary steal
administation of dypridamole or adenosine aka vasodilators will make existing ischemia worse, helps detect ischemic coronary artery perfusion
common occluded coronary arteries (MI)
LAD> RCA>circumflex
MI presentation
diaphoresis nausea/vomiting severe retrosternal pain crushing pain in left arm/jaw shortness of breath fatigue
postinfarction fibrinous pericarditis
1-3 days post MI
Dressler syndrome
autoimmune polyserositis aka fibrinous pericarditis. Weeks post MI
