The appearance of the LA myxoma on M-mode mimics what other condition commonly seen with M-mode?

ruptured sinus of valsalva
cor triatriatum
mitral stenosis
flail leaflet

mitral stenosis

myxoma may be tethered in sucha way that it follows the flow from the LA into the LV. The myxoma then appears as a structure posterior to the anterior mitral leaflet and, depending on its density maybe thought to be a thickening of the mitral leaflet. 2D echo helps to define the structure
Of the following, which is NOT a criterion for idopathic hypertrophic subarotic stenosis(IHSS)?

asymmetric septal hypertrophy
midsystolic A-V notching
systolic anterior motion on the mitral valve
high-frequency oscillations of the mitral valve

high-frequency oscillations of the mitral valve

high frequency oscillations are not noted in IHSS
Symmetrical hypokinesis is a differentiating echo feature for

ischemic heart disease
hypertrophic cardiomyopathy
dilated cardiomyopathy
congenital aortic stenosis

dilated cardiomyopathy

dialted cardiomyopathy usually involves all myocardial cells
Systolic anterior motion(SAM) is most commonly associated with which of these conditions?

LV aneurysm
LA myxoma
idiopathic hypertrophic subaortic stenosis(IHSS)
aortic insufficiency
idiopathic hypertrophic subaortic stenosis(IHSS)

to confirm a diagnosis of IHSS, both asymmetric septal hypertrophy (ASH) and systolic anterior motion (SAM) must be noted.
Right ventricular volume overload(RVVO) is associated with the spetal motions of:

diastolic "double dip"
anterior motion in early systole
anterior motion in late systole
akinesis

anterior motion in early systole

in RVVO the septal motion becomes paradoxical
The motion of the IVS typically noted in the LBBB (left bundle branch block)

breaking
paradoxial
flat
hyperkinetic

breaking

breaking is noted in LBBB, Wolff-Parkinson White syndorme and RV pacing
T/F: An increase in E-point spetal separation is used to evaluate

LV function
aneurysms
LV dilatation
RV infarction
