In bicuspid aortic valves- the primary issue is?

Select one of the following:

  • disruption to annulus

  • fused commissure

With calcific aortic "wear and tear", leads to lipids, inflammation, calcification. This the cusps. You can have loss of % with no symptoms. The sequelae is obstruction to flow which increases the load of the . The LV adapts by . Once symptoms occur average survival is years. The only effective treatment is .

Question 6 of 14

Medal-premium 1

In 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?

Select one or more of the following:

  • Increased LV end-diastolic pressure

  • Eccentric LV hypertrophy

  • Concentric LV hypertrophy

  • Decreased Stroke volume

  • Widened pulse pressure

Question 7 of 14

Medal-premium 1

The mitral valve has how many leaflets?

Select one of the following:

  • 1

  • 2

  • 3

  • 4

Question 8 of 14

Medal-premium 1

Mitral regurgitation can occur due to?

Select one or more of the following:

  • leaflet abnormalities

  • chordae

  • papillary muscle

  • LV muscle /wall

  • Annulus

Question 9 of 14

Medal-premium 1

Select from the dropdown lists to complete the text.

During mitral regurgitation endocarditis destroys ( cusps, myocardium, blood vessels ) and ruptures chordae. Rheumatic valve disease leads to scarring and retraction. Mitral valve ( prolapse, stenosis, hypertrophy ) occurs by expansion and elongation. Papillary muscle are affected during ( infarction, ischaemia, birth ).

Question 10 of 14

Medal-premium 1

Which of these are common symptoms of acute mitral regurgitation?

Select one or more of the following:

  • Increased L ventricle pressure

  • Increased L atrial pressure

  • Decreased Cardiac Output

  • Pulmonary oedema

  • Pitting oedema

Question 11 of 14

Medal-premium 1

In chronic mitral regurgitation there is left ventricle concentric hypertrophy?

Select one of the following:

  • True
  • False

Question 12 of 14

Medal-premium 1

Fill the blank spaces to complete the text.

Rheumatic stenosis takes to develop. It leads to valves, of commissures, and thickened . Left pressure rises, and pulmonary is common. Mitral stenosis can be treated by surgery involving valve replacement and .

Question 13 of 14

Susceptibility to infective endocarditis involves?

Select one or more of the following:

  • Valve abnormalities

  • Prosthetic valves

  • IV drug users

  • Nosocomial infections

  • Young patients

  • HIV

Question 14 of 14

Medal-premium 1

Endocarditis complications include?

Select one or more of the following:

  • embolisms

  • glomerulonephritis

  • pulmonary fibrosis

  • systemic hypotension
