Persistent Truncus Arteriosus
Due to failure of aorticopulmary septum to spiral?
Transposition of Great Vessels
What bedside maneuver would improve cyanosis in Tetrology of Fallot? why?
Squatting - inc systemic vasc resistence, dec R–> L shunt
Which congenital CV disease assoc with maternal mood disorder?
Ebstein anomaly - can be caused by Li exposure in utero if mother is bipolar
CV disease due to failure of neural crest cells to migrate?
Persistent truncus arteriosus
What stimulates the baroreceptors near the heart and what is the result?
Hypotension; Vasoconstriciton and increasing HR, BP and contractility
Cushing Reflex triad
hypertension, bradycardia, respiratory depression
Types of chemoreceptors and stimulators for them
Peripheral: lower Po2, lower pH, high PCo2
Central: changes in pH and PCo2 (brain interstitial fluid)
What does PWCP measure (approximate)?
Left atrial pressure (<12mmHg)
Hypoxia’s effect on the Lung’s vessels
Vasoconstriction
Metabolites that influence the heart
Adenosine, NO, CO2, low O2
Metabolites that influence skeletal muscle during exercise
Adenosine, CO2, lactate, K, H
formula for net fluid flow
Kf[(Pc-Pi)-c(pic-pii)]
Edema is commonly caused by
increasing capillary pressure(HF)
decreased plasma proteins(nephrotic syndrome, liver failure, protein malnutrition)
increased capillary permeability (toxins, infxns, burns)
increased fluid colloid osmotic pressure (lymph blockage)
R->Left Shunts 5T’s
Truncus arteriosus Transposition Tricuspid atresia Tetraolgy of Fallot TAPVR
Frequency of L-R shunt CV disease from most common to least?
VSD>ASD>PDA
Which L-> R shunt assoc with Cri du Chat?
VSD
Female patient with broad chest and widely spaced nipples and streak ovaries would likely have which Congenital CV disease
Preductal Coarctation of Aorta or Bicuspid Aortic valve - this woman has Turners
Late cyanosis in lower extremities
PDA
Assoc with notching of ribs
post ductal Coarctation of Aorta
Assoc with clubbing of fingers and polycythemia?
Eisenmenger Syndrome
In persistent truncus arteriosus, most patients have accompanying
VSD
D-transposition of great vessels is due to what? What is the life expectancy of infants
failure of aorticopulmonary septum to spiral.
Most infants die within the first few months of life.
Tricuspid atresia is
Absence of tricuspid valve and hypoplastic RV
Symptoms of Tetralogy of Fallot
1 Pulmonary infundibular stenosis
2 RVH
3 Overriding aorta
4 VSD
TAPVR Total anomalous pulmonary venous return is associated with
ASD and sometimes PDA to allow for right->left shunting to maintain cardiac output.
Ebstein anomaly is seen if the mother has bipolar disease and ingested
Lithium exposure in utero
If Sahaja drinks too much this weekend with Rachita, what is her child at risk for developing?
VSD, PDA, ASD, Tetrology of Fallot
A pt with a microdeletion of chromosome 7 would likely have what disease?
Supravalvular aortic stenosis, pt has Williams
Mother has fever, infection, swollen lymph nodes and rash that travels down the body during pregnancy - child is at risk for?
PDA, Pulm a stenosis, septal defects
Tall man with abnormally long arms are prone to which heart disorders?
MVP, Aortic regurgitation, thoracic aortic aneurysm
