Anatomy Flashcards
Posterior medial papillary muscle supplied by which coronary artery (s)
PDA
Anterolateral papillary muscle supplied by coronary artery (s)
LAD and circumflex, making it less susceptible to ischemia 
What determines “dominant coronary artery”
Whichever one gives rise to PDA…
Chagas diseas
-Latin America
–LV apical aneurysm.
– nonischemic cardiomyopathy. 
Cardiac sarcoid area affected?
-Endocardium of the anteroseptal and apex of the LV.
– focal hypokinesis of affected regions. 
Pseudoaneurysm.
– complication of
– describe.
-Mechanical complication of MI
-Myocardial necrosis leads to contained ventricular rupture.
– narrow neck
– wall formed by pericardium.
Left atrium, measured where
End systole.
– apical 4C
– apical 2C
Then indexed for body size 
Partial anomalous, pulmonary venous return
L transposition
Ventricles are reversed
D transposition (dead)
Great vessels are reversed.
Must have leaks/chance to survive.
Fix with either
arterial switch
or intra-atrial baffle.
(Mustard-Senning)
Three tricuspid valve leaflets
Septal, anterior and posterior.
Septal is obviously medial.
Aneurysm
All three layers: intima, media, adventitia
Thinned, dyskinetic myocardium
Pseudoaneurysm
Two layers: media, adventitia.
Usually direct trauma/rupture of ventricular free wall.
Contained by pericardium.
Narrow neck.
Surgical consult
Another name for the inferolateral segment?
Posterior segment.
How to tell paracardial from plural effusion on echo
Pericardial effusion anterior to descending aorta.
Plural effusion posterior to descending aorta on PLAX
Respiratory variation for Tamponade/constriction
Mitral valve 25%
Tricuspid valve 40%
Cor triatrium (dexter)
Potentially obstructive membrane that can develop in the right atrium
Cor triatrium (sinister)
Occurs in the left atrium above the LAA, theoretically, could impair growth of downstream structures, including arch…
Associated with coarctation? (3)
Bicuspid aortic valve
subaortic membrane/stenosis
mitral valve abnormalities
Shone complex (4)
Supramitral valve ring.
Parachute mitral valve.
Subaortic stenosis,
Coarctation of the aorta.
Shone like complex
Any subset of multiple left-sided obstructive lesions
DORV
Double outlet right ventricle
Aortic and pulmonary valves, committed to RV and usually associated with VSD.
Usually presents/surgical repair during childhood.
Tricuspid atresia
3functional cardiac chambers
lack of direct connection between RA & hypoplastic RV
Presents young.
Fontan palliation. 
Marfan’s associated with what (4)
Mitral valve prolapse.
Tricuspid valve prolapse.
Dilatation of SoValsalva
Dilation main PA
