Wall-to-Wall
The LV is divided into this many wall segments
What is 17?
The coronary arteries originate from the base of this vessel
What is the aorta?
The M in M-mode stands for this
What is motion?
The aortic root is measured during this phase
What is end-diastole?
The LVOTd must be measured during this portion of timing
What is mid-systole?
These are the two mid level segments from the apical LAX view
What are anteroseptal and inferolateral?
This coronary artery normally supplies the anterior LV, apex, and anterior 2/3s of the septum
What is the LAD?
The M-Mode beam should be positioned this way relative to the structure
What is perpendicular?
On mitral valve M-Mode, this represents peak early-diastolic opening
What is the E point?
A measurement of 20 - 30 mm is considered the average for this structure
What is the RVIDd?
These are the two segments opposite the septum from the mid level PSAX view
What are anterolateral and inferolateral?
This is the most common type of coronary dominance
What is right dominance?
M-Mode produces this type of 'icepick' view
What is a one-dimensional view?
This is the normal EPSS measurement
What is less than 6 mm?
This may be identified as the peak of the R wave
What is end-diastole?
This is the basal segment near the pericardium from the PLAX LV view
What is inferolateral?
In left-dominant circulation, the PDA originates from this artery
What is the LCx?
M-Mode is approximately this many times better than 2D imaging for timing cardiac events
What is 1 - 2,000 times?
'C' on M-Mode represents this
What is mitral valve coaptation?
This should always measure less than the aortic root
What is the main pulmonary artery?
This is the first wall you see when looking at a PLAX LV view
What is the RV free wall?
In co-dominant circulation, these two arteries share the inferior cardiac blood supply
What are the RCA and LCx?
This feature makes M-Mode especially useful for evaluating rapidly moving structures
What is high temporal resolution?
1.5 - 2.6 cm is the normal range for this M-Mode structure
What is the aortic cusp separation?
There should be less than a 10% difference between these two measurements
What is the length of the apical 4 and apical 2 views?
