Moucellaneous Flashcards
MC peds cardiac tumor
rhabdo (60-80%), think tuberous sclerosis
tuberous sclerosis!
rhabomyoma
rhabdomyoma genetic disease
tuberous sclerosis
Px rhabdomyoma
regression, usually do nothing unless obstruction
spider cells
rhabdomyoma
multiple tumors vs. rhabdo
multiple rhabdo, fibroma single
calcified tumor
fibroma (also can be cystic)
location rhabdo vs. fibroma
rhabdo atrial or ventricles INTO the chamber, fibroma likely inside the wall of the ventricle or intraventricular
pericardial tumor with pericardial effusion
teratoma
tumor associated with AV reentry?
rhabdomyoma, abnormal AV connection through tumos
Dx hemangioma with echo?
color doppler the tumor
MC virus of myocarditis
coxsackie B > A
myocarditis with incessant VT
likely parvovirus (parVoVirus)
myocarditis with coronary involvement
parvovirus
features of parvovirus
incessant VT, coronary involvement, arrhythmia
abnormal desmosomal proteins leads to which disease
ARVC
abnormalities in myosin binding protein C leads to what disaease
HCM
HCM abnormality
myosin binding protein C
ARVC abnormal protein
desnisinak protein
diagonal branches come off the…
LAD (l a D for diagonal)
obtuse branches come off the
Circ (Obtuse starts with O which is a Circle)
acute marginal branches come off the
RCA
coronary branches
LAD-> diagonal
circ -> obtuse marginal
RCA -> acute marginal
what is the ramus intermedius?
normal variant arise from LAD-Circ bifurcation (becomes a trifurcation)
first most important prognostic factor on VAds that can be assessed by echo? 2nd?
- RV function
2. Ao regurgitation (moderate and severe are bad)
Speed of sound in tissue =
1540 m/s
which apo is bad?
Apo B=Bad, responsible for atherogenicity of chylomicrons through LDL, ApoA is for HDL
threshold to treat LDL?
> 190 or high risk/famhx >160
first line tx Hcholesterol?
statin, 2nd line ezetimibe or cholestyramine
side effect of cholestyramine?
cholesterol lowering agent that increases lipids
meds for lipids
The Fs: fibric acid, gemfibrozil, fish oil
If someone is on a statin and has hyperlipidemia, what is the drug of choice?
DON”T use gemfibroizil, will cause rhabdomyolysis (gem = ruby red)
