Davies- Evaluation for Cardiomyopathy

  1. 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
  2. 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
  3. 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
  4. 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.

  5. 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
    anterior motion in early systole

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


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

    LV function
    LV dilatation
    RV infarction
