Name that measurement!
This acronym represents the widest linear measurement of the LV.
What is the LVIDd?
The LA measurement is performed in the A4C view during this part of the cycle.
What is end systole? Also performed in A2C.
A measurement of 5.0cm is obtained when placing the calipers on the aortic root.
What is an aneurysm?
What is the:
1. EF% = (EDV – ESV)/ EDV x 100 OR
2. EF% = SV /EDV X 100 ?
What measurement allows for the assessment of LV wall thickness?
What is LV mass?
This measurement is taken in the PLAX view at level of valve hinge points.
What is LVOT?
The LVOT is measured during this part of the cycle.
What is mid-systole? (With AV fully open, leaflets abutting the sinuses)
What is dilated cardiomyopathy or dilated LV?
The volume using the biplane or Simpson's relies on LV as a bullet and this number of discs to calculate volumes.
What is 20 equidistant discs across the LV?
What is biplane or Simpson's MOD for EDV and ESV.
This structure is measured using the posterior sinus as a landmark.
The ascending aorta is performed during this part of the cycle.
What is end-diastole?
The RWT is 0.40 and the WM is 110g/m2 in a 55yo female.
What is concentric hypertrophy?
What is the BMI as obtained from the patient's height and weight.
Examination of this structure may determine the reason for an elevated LV mass.
What is AV for AS?
A subcostal view is best for performing this 2D measurement.
What is the RV wall thickness?
LV mass is calculated at which part of the cycle?
The basal anteroseptal wall measures 1.3cm and the basal inferolateral wall measures 0.7cm on a PLAX in a female during her echocardiogram.
What is septal hypertrophy?
This is the unit of measurement for the LV Mass.
What is gm/m2?
Assessment of this valve condition may explain an LAi of 38ml/m2.
What is mitral regurgitation?
This measurement is performed in the A4C RV focused view.
What is the basal RV measurement?
The IVC measurement is obtained using this technique for full expansion of the vessel.
What is expiration?
Note inspiratory collapse relates to RAP.
A FAC of 62% is obtained by tracing the area of the RV.
What is a normal or healthy RV function?
The LV mass requires which additional measurement(s) in addition to the LVPWd thickness?
What is the IVSd and the LVIDd?
Formula:
LV Mass = 0.8 (1.04 ( (LVIDd + IVSd + PWd)3 − LVIDd 3) ) + 0.6
These three factors will cause greater intra and interobserver variability.
What is:
1. patient physiologic variability (ie HR),
2. Image acquisition (ie. endocardial definition) and
3. measurement variability in tracing the endothelial borders.?
