Module 1: Cardiothoracics Flashcards
right atrium is defined by
the IVC
what is the crista terminalis
muscular ridge from superior to inferior vena cava.
right ventricle is defined by the
moderator band
tricuspide papillary muiscles inert on the
septum
crista supraventricularis is what
thick muscle sperating AV and tricuspid valve
aortic and mitral realtion
side by side, no muscle between them
chest xr double density sign is
direct sign of left atrium enlargement
other signs of dilated left atrium
splaying of the carina (over 90 degrees)
mitral valve connected to papillary muscles via
chordae tendinae
papillary uscles of the left ventricle insert on to l
lateral and posteiror walls
NOT septum like the right side
echogenic focus in left ventricle on prenatal scanning is ax with
increase risk of downs
dumbell appearance of fat desnity in atrial septum
lipomatous hypertrophy of the intra atrial septum
Lipomatous hypertrophy of intra atrial septum spares the
fossa ovalis
why is lipomatous hypertrophy hot on PET
made of brown fat
RCA perfuses the SA node by
60%
RCA perfuses the AV node by
90%
most common and most serious malignant origin of coronary artery
LCA form the right coronary sinus coursing between aorta and pulmonary artery
What to do if anomolous left off the right cusp
always repair
what does ALCAPA stand for
Anomalous left coronary from the pulmonary artery
two types of ALCAPA are
infantile
- steal syndrome.
adult
what is steal syndrome in ALCAPA-
reversal of flow in LCA as pressure decreases in the pulmonary circulation
what is myocardial bridging?
intramyocardial course of a coronary artery.
definition of coronary artery aneurysm
diamter of 1.5x normal
common cause of coronary aneurysm
atherosclerosis
Coronary fistula defined
connection between coronary artery and cardiac chamber
contraindications to beta block in cardiac CT
severe asthma
heart block
acute chest pain
recent cocaine
which types of heart block are contraindicated to beta blockers
2nd and 3rd.
1st is not
contraindications to GTN
hypotensive
severe aortic stenosis
hypertrophic obstructive cardiomyopathy
Viagra use
how to quantiy velocity of blood in MRI
Velocity mapping also called phase-contrastr imaging
also called velocity encoded cine MR imaging
cause of congenital aortic stenosis
bicuspid
dilatation of the ascending aorta from stenotic valve due to
Jet phenomenon
- valvular (most common)
- subvalvular
- supravalvular
Williams syndrome is which stenosis
supravalvular stenosis of aorta
Bicuspid aortic valve and coarctation think
turners syndrome
most common congential heart disease
bicuspid valve
then VSD
associations of biscupid aortc valve
Turners and coarctation
Cystic medial necorsis
PKD
aortic regurg is seen in which conditions
bicuspid valve
bac endo
marfans
HTN dilated aortic root
aortic dissection
commonest cause of mitral stenosis
rheumatic heart disease
common cuae of mitral regurgitation
endocarditis or papillary muscle/chordal rupture post MI
isolated right upper lobe pulmonary oedema is ax with
mitral regurgitation
pulmonary stenosis is ax with
Noonan syndrome
Peripheral pulmonary stenosis is seen in
Alagille syndrome
which is a disease where kids wijh absent bile ducts
diverse disease, rare
what is rheumatic heart disease
immune modulated response to Group A beta haemolytic stre
Tricupsid regurg is common form of tricuspid disease due to
weak annulus
How does tricuspid regurg happen in carcinoid
serotonin degrades the calve
Triscupsid Regurg causes what in the right ventricle
RV dilatation
What is Ebsteins anomaly
kids whose mums were on lithium
tricuspid valve is hypoplastic and psoterior lead is displaced apically.
enalrged RA, decreased RV and TR
Tricuspid atresia - occurs in what congenital anomaly
RV hypoplasia
Tricuspid atresia will also have
an ASD or PFO
asplenia
