  1. 1Which factors predispose valves to pathology?
    1. Acontain lymphoid tissue
    2. Bhighly avascular
    3. Chighly vascular
  2. 2The aortic valve has 3 cusps, right, left and [blank_start]non-coronary[blank_end]. Each cusp has [blank_start]sinus of valsalva[blank_end] which is important for [blank_start]coronary[blank_end] flow. Common pathology includes aortic [blank_start]stenosis[blank_end] and aortic [blank_start]regurgitation[blank_end].
    1. Anon-coronary
    2. Bsinus of valsalva
    3. Ccoronary
    4. Dstenosis
    5. Eregurgitation
  3. 3Aortic stenosis can be [blank_start]congenital[blank_end], rheumatic valve disease, [blank_start]bicuspid valve[blank_end], calcification of trileaflet > [blank_start]70 years.[blank_end]
    1. Acongenital
    2. Bacquired
    3. Cbicuspid valve
    4. Dmono-cuspid valve
    5. E70 years.
    6. F30 years
  4. 4In bicuspid aortic valves- the primary issue is?
    1. Adisruption to annulus
    2. Bfused commissure
  5. 5With calcific aortic [blank_start]stenosis[blank_end] "wear and tear", leads to lipids, inflammation, calcification. This [blank_start]immobilises[blank_end] the cusps. You can have loss of [blank_start]50-70[blank_end]% with no symptoms. The sequelae is obstruction to flow which increases the load of the [blank_start]LV[blank_end]. The LV adapts by [blank_start]concentric hypertrophy[blank_end]. Once symptoms occur average survival is [blank_start]2-3[blank_end] years. The only effective treatment is [blank_start]valve replacement[blank_end].
    1. Astenosis
    2. Bimmobilises
    3. C50-70
    4. DLV
    5. Econcentric hypertrophy
    6. F2-3
    7. Gvalve replacement
  6. 6In aortic regurgitation blood leaks back from the aortic root into the left ventricle. Abnormalities include congenital disease, rhematic heart disease, endocarditis and trauma. The primary pathology occurs during diastole. Distortions to the aortic root occur with HTN, Marfans, ankylosing spondylitis, syphilis, and aortic dissection. What is the compensation of the heart?
    1. AIncreased LV end-diastolic pressure
    2. BEccentric LV hypertrophy
    3. CConcentric LV hypertrophy
    4. DDecreased Stroke volume
    5. EWidened pulse pressure
  7. 7The mitral valve has how many leaflets?
    1. A1
    2. B2
    3. C3
    4. D4
  8. 8Mitral regurgitation can occur due to?
    1. Aleaflet abnormalities
    2. Bchordae
    3. Cpapillary muscle
    4. DLV muscle /wall
    5. EAnnulus
  9. 9During mitral regurgitation endocarditis destroys [blank_start]cusps[blank_end] and ruptures chordae. Rheumatic valve disease leads to scarring and retraction. Mitral valve [blank_start]prolapse[blank_end] occurs by expansion and elongation. Papillary muscle are affected during [blank_start]infarction[blank_end].
    1. Acusps
    2. Bmyocardium
    3. Cblood vessels
    4. Dprolapse
    5. Estenosis
    6. Fhypertrophy
    7. Ginfarction
    8. Hischaemia
    9. Ibirth
  10. 10Which of these are common symptoms of acute mitral regurgitation?
    1. AIncreased L ventricle pressure
    2. BIncreased L atrial pressure
    3. CDecreased Cardiac Output
    4. DPulmonary oedema
    5. EPitting oedema
