L. subclavian artery & ligamentum arteriosus
Acs Ao starts from _____ and ends at _____
sinotubular junction
brachiocephalic (innominate) artery
_____ branches off from RCA then supply RV
AM (acute marginal)
The acute marginal artery is the longest branch of the right coronary artery on the anterior aspect of the heart and extends towards the cardiac apex. The name reflects the fact that this artery runs along the anteroinferior border of the heart
Functional LVOT refers to
the area between the septal wall to the anterior aortic annulus and from the anterior mitral leaflet to the posterior aortic annulus
Anatomic LVOT refers to:
extension from the inner edge of the IVS to the leading edge of the anterior mitral leaflet
average LA pressure?
0-12mmHg
The ratio of total pulmonary blood flow to total systemic blood flow, the Qp/Qs ratio, is a useful tool for quantifying the net shunt. A Qp/Qs ratio of _____ is normal and usually indicates that there is no shunting
1:1
Mid LV location ?
PSAX pap level wall segments (6)
anterior
anteroseptal
anterolateral
inferior
inferoseptal
inferolateral
*pap muscle: inferior pap & anterolateral pap

The main mitral valve apparatus components are:
1) mitral annulus, 2) mitral valve leaflets, 3) chordae tendineae and 4) papillary muscles
What are the boundaries of the LVOT?
