cardio anatomy Flashcards
Enlargement of what leads to dysphagia
left atrium
on cxr what forms ant border of the heart
rv
transesophageal probe will affect which chamber
la
which chamber will be affected when injury will be at 3rd-4th Intercostal Space
rv
location of sa node
Right atrium along roof (proximity
to opening of SVC)
slowest conduction velocity at
av node
a fib ablation will be done at
b/w la and pulm vein osteia
medial injury at 5th Intercostal Space affects what
lv and left lung
loc of av node
Right atrium along interatrial
septum (proximity to tricuspid valve and
coronary sinus)
lateral injury at 5th Intercostal Space affects what
left lungs
loc of bundle of his
memb portion of intra ventricular septum
a flutter ablation will be done at
coronary sinus
sa node is supplied by
rca
Embryologic derivative of coronary sinus
sinus venous
Pulmonary capillary wedge pressure: Surrogate marker for?
la pressure
anterolateral papillary
muscle will be supplied by
lca
Posterior Descending Artery (PDA): supplies
Primarily inferior borders of heart
* Posterior 1/3 of interventricular septum
* Posteromedial papillary muscle
Biventricular pacemaker lead placement into LV is done thru?
coronary sinus
coronary sinus will be dilated in case of?
pulmonary hypertension
Direct measurement of left atrial pressure thru which catheterization
Trans-Septal Left Atrial Catheterization
which catheterization measures right-sided pressures
swan-ganz
biventricular catheterization leads?
1st lead at ra via subclavian vein
2nd at RV thru ra; has icd which shocks a pt in case of arrhythmia to bring it back to sinus rhythm
3rd at lv thru coronary sinus
mitral valve regurgitation will lead to enlargement of?
la
wide mediastinum in seen in case of
asc aortic aneursym
pulm anthrax
mediastinal tumor
on ct saddle shape structure at the pulmonary trunk indicates?
pe
on ct +ce of the false lumen in aorta indicates?
aortic dissection
