OPTION LIST

 

A	Acute rheumatic fever	I	Myxomatous mitral valve
B	Aortic regurgitation	J	Non-bacterial thrombotic endocarditis
C	Aortic stenosis – degenerative (calcific)	K
D	Aortic stenosis - rheumatic	L
E	Carcinoid Heard disease	M

H	Libman-Sacks endocarditis	P

 

 

For each scenario below, choose the most appropriate answer from the list above. Each option may be used once, more than once or not at all.

 

1. Fibrous thickening and distortion of the mitral valve creating a ‘fishmouth’ or ‘buttonhole’ stenosis

 

 

2. Small, sterile, pink vegetations. Can be on both sides of the valve leaflets or elsewhere on the endocardial surface.

 

 

3. Aschoff bodies and Anitschkow cells present. Valve involvement presents as fibrinoid necrosis along the lines of closure forming 1-2 mm verrucal vegetations.

 

 

4. Ballooning (hooding) of the mitral leaflets is followed by their prolapse into the left atrium

 

 

5. Friable, bulky and potentially destructive vegetations that can extend onto the chordae
