1

What is likely cause of this dilated cardiomyopathy?

 

 

Q image thumb

viral myocarditis --> cocksackie B

 

note the central lymphocyte aggregation and surrounding myocyte necrosis

2

What is possible cause of this dilated cardiomyopathy?

Q image thumb

Fungal myocarditis [aspergillus = septate hyphae branching at acute angle]

3

What is possible cause of this dilated cardiomyopathy?

Where do you get it from? What does the black arrow point to?

Q image thumb

Chagas disease

 

the arrow points to amastigotes within cytoplasm

 

T. cruzi transmitted by reduviid bug

4

What is cause of this dilated cardiomyopathy?

Q image thumb

giant cell myocarditis

 

arrow points to multinucleated giant cells and interstitial infiltrate

 

rare but fatal

5

What is cause of this dilated cardiomyopathy?

Q image thumb

hypersensitivity myocarditis

 

arrows pointing to eosinophiles

interstitial edema

6

What is cause of this dilated cardiomyopathy?

Q image thumb

hemochromatosis

 

brown = cytoplasmic iron pigment

 

could also use prussian blue stain for iron

7

Which of these is hypertension and which is hypertrophic cardiomyopathy?

Q image thumb

Left is hypertrophic cardiomyopathy [HCM] = hypertrophy preferentially in interventricular septum

Right is hypertension = hypertrophy everywhere in LV

8

What feature of hypertrophic cardiomyopathy is this?

Q image thumb

fiber disarray

9

What type of cardiomyopathy? What is cause?

 

 

Q image thumb

Restrictive cardiomyopathy due to amyloidosis

10

What is this? stain?

Q image thumb

polarized congo red stain confirming amyloids

means this is likely restrictive cardiomyopathy

11

What is changing in these curves?

 

Q image thumb

increase preload

12

What is changing in these curve?

Q image thumb

Contractility

13

What is changing in these curves?

Q image thumb

Changes in total peripheral resistance [TPR] = afterload

14

What kind of dysfunction in this figure?

Q image thumb

Systolic dysfunction = systolic heart failure

15

What kind of dysfunction?

Q image thumb

diastolic dysfunction

16

What kind of hypertrophy?

Q image thumb

concentric hypertrophy

17

What kind of hypertrophy?

Q image thumb

eccentric hypertrophy

18

What is this? What it is associated with?

 

step1

Aschoff body = focus of chronic inflammation with fibrinoid material and giant cells and containing anitschkow cells

 

sign of myocarditis in rheumatic fever

19

What is this? What is it associated with?

step1

Q image thumb

anitschkow cell

asosciated with myocarditis in rheumatic fever

located usually in aschoof body
