❗c.f :- segmental narrowing
of aorta

Slide 8
1st picture

Ch. feature :-
- straight edge
- normal base
- No nodules or mass
- complete closure if closed .

2nd picture
D:- valvular stenosis.
Ch. features :-
- fusion edges
- incomplete opening
" stenosis"

3ed picture
D :- valvular regurgitation
" incompetence" " insufficiency"
Ch. features :
- incomplete closer if closed

- traction of leaflet .

Slide 9
❗ D :- multiple MI
❗ ch. feature :- scar formation " fibrous tissue "
- Non-infaracted: Brick red tissue.
acute: unstained pale.
subacute: mottled yellowish.
healed: White glistening.

Slide 10
❗ D :- systemic hypertension.
❗c.f :-
cardiac hypertrophy
A: Left systemic hypertensive heart disease.
Feature: Concenteric thickening of the lt vent and decrease its lumen.

B:cor pulmonale.
Rt vent. is markedly dilated and hypertrophied..

Slide 11

Slide 12
❗ D :- mitral valve prolapse
❗ c.f :-
- mitral valve regurgitation because it become ballooning.
- Myxoid substance " blue substance "

Slide 13
❗ D :- rheumatic heart disease
❗ c.f :- Aschoff
body in acute rheumatic
carditis.

Slide 14
❗ D :- Rheumatic myocarditis
❗c.f :- Presence of Aschoff bodies.

Slide 15
❗ D: Rheumatic
heart disaese
❗ c.f : Aschoff
bodies with binucleated macrophage.

Slide 16
1.
❗ D :- Dilated cardiomyopathy
❗ c.f :-
Dilation of all chambers
بخلاف الdilation الذي بسبب ال hypertension يحدث
dilation only in 2 chambers

2.
❗D :- hypertrophic cardiomyopathy
❗c.f :- hypertrophy of all cardiac muscle .
بخلاف الذي يحصل بسبب hypertension يكون ققي في
1 chamber

3.
❗D :- restrictive cardiomyopathy
❗c.f :-
loss of cardiac compliance.

Slide 17
❗ D :- sample of hypertrophic
cardiacmyopathy.
❗ c.f :-
Irregular ( abnormal distorted ) cardiac myocyte

Slide 18
❗D :- Dilated cardiomyopathy

❗ c.f :-
- small myocyte and between them more C.T

Slide 19
❗D :- types of vegetation
❗ c.f :-
1. RHD :
- small vegetation ( warty ) at site of closure .
- normal valve tissue .
2. IE :
- large vegetation
- destructive valve tissue
3. NBTE :
- mass of thrombus ( small bland ) attached to the valve
4. LSE
- similar to NBTE but on both sides .

Slide 20
❗ D :- infective endocarditis.
❗ c.f :-severe inflammation with vegetation in the edge of leaflets and upper and lower.

Slide 21
❗ D: infective endocarditis
❗c.f : bacterial colonies + fibrin
deposition + inflammatory cells

Slide 22
Similar slide21

Slide 23
Similar slide 21

Slide 24
❗ D: NBTE

❗ c.f : slight or no inflammation with fibrin no bacteria

Slide 25
❗ D: NBTE

❗ c.f : slight or no inflammation with fibrin no bacteria

Slide 26
❗ D: Acute myocarditis
❗ c.f :-
- Neutrophilic infiltrate in
between myocyte
-not MI because here
muscles and nucleus are intact
and viable no necrosis
 In MI cells are dead
“ necrosis “ no nucleus
not MI.
