|
For which isomerism are you most likely to have arrhythmias, and why
|
Left isomerism: lack of SA node so you have development of an ectopic pacemaker (or a few)
|
|
|
what pathologies give holosystolic murmurs
|
AV valve regurg
VSD |
|
|
What pathologies give continuous murmurs
|
PDA
the pressure in the aorta is always higher than the pressure in the pulmonary artery. there is always blood in the aorta, either forwards or backwards flow |
|
|
What are the 5 cyanotic shunts we have learned
|
eisenmenger
Tet transposition of great arteries common atrium common ventricle |
|
|
do you see LV hypertrophy in ASD?
|
no because extra blood goes though the atrial wall and normal flows through to the ventricle. therefore have increased flow in Right side ONLY
|
|
|
a dilated right ventricle gives you what physical sign
|
a systolic heave (due to dilation and extra force of contraction)
|
|
|
Natural history of VSD?
|
any size VSD may spontaneously close by age 2
|
|
|
why do you only get lower extremity clubbing and cyanosis in PDA turned eisenmenger
|
because the PDA is after the aortic branches, so the blood flow to upper extremities is not affected. ONLY lower extremities
*only happens at late stage eisenmenger |
|
|
what are the 4 features of tet
|
1. pulmonary stenosis
2. overarching aorta 3. VSD 4. LV hypertrophy |
|
|
what murmur do you get with tet
|
due to the stenosis: cres-decres in systole
due to the vsd: holosystolic |
|
|
how do you treat TGA
|
1. percutaneous: make a hole in the atria
2. surgical: switch the arteries (with the coronaries too!) |
|
|
how does a pre ductal coarctation differ from a post ductal coarctation
(anatomy and clinical presentation) |
preductal will have the ductus arteriosus remain open
deoxygenated blood will shunt R to L. Lower body perfused with deoxygenated blood, upper body perfused with oxygenated blood results in differential cyanosis ***postductal does not have cyanosis anywhere! no deoxygenated blood is mixing |
|
|
On auscultation of his chest, a 32-year-old man is found to have a widened, fixed splitting of S2 and a systolic murmur at the left sternal border. What is the most accurate diagnosis?
|
ASD
fixed since in inspiration some more blood drawn to pulmonary circulation but during expiration more blood is shunted back to the R side |
|
|
A two-month-old infant born with a large ventricular septal defect goes into congestive heart failure. Which of the following drugs would be administered as first line treatment?
|
digoxin
|
|
|
Oxygen Saturation Measurements: superior vena cava 70%, right atrium 70%, right ventricle 70 %, pulmonary artery 95%, pulmonary vein 99%, left atrium 99%, left ventricle 99%, aorta 75%

TGA
