Embryology

Question 1

Fold of the L loop sits at the

LV and RV development

Atrium v ventricle

Answer 1

junction of the bulbus cordis and ventricle

LV= ventricle
RV- BC

Atria are pushed to the top

Question 2

Endocardial cushions meet at the

Answer 2

AV orifice and become M/T valves

Question 3

Fetal circulation

Oxygen comes from

LH gets blood from

RV blood is pumped to

Answer 3

Little blood to lungs

Placenta

FO from RA

PA to DA to Aorta

Question 4

DiGeorge Syndrome 22q11

Flow inc with

Answer 4

ToF

Greater pressure, less resistance

Question 5

Eisenmenger Syndrome

signs and symptoms

Answer 5

Long standing LtR (VSD, PDA)

Irreversible PVD (high PVR)

RtL due to resistance, cyanosis

Cyanosis, polcythemia, bleeding, stroke, gout, gallstones, clubbing, hyperviscosity

Question 6

AV Canal

Signs

Answer 6

atrial and ventricular defects

single common AV valve

Lots of pulmonary flow, CHF, enlargement of all 4 chambers

Question 7

PDA

Type of shunt?
Enlarged?
Result?

Answer 7

L to R shunt

LA and LV enlarged, results in inc pulm circulation

less blood flow to other areas

Question 8

Coaractation site

LE?

Answer 8

beyond SC artery, almost always related to PDA

Decreased BP in lower extremities

Question 9

Cyanosis complications

Answer 9

slow growth
decreased exercise tolerance
Neuro deficits
Hemorrhage
