Regarding Valvular Heart Disease, which of the following is not MATCHED:

A) Stenosis : disruption of the supporting structures

B) Insufficiency: It can appear abruptly, as with chordal rupture, or insidiously

C) Stenosis: calcification or valve scarring

D) mitral valve : being the most common target

The outcome of valvular disease depends on all of the following except:

A) the valve involved

B) the degree of impairment

C) the quality and timing of the murmur

D) the effectiveness of compensatory mechanisms.

E) All of the above can give a clue on the outcome and prognosis

3 Degenerative Valve Disease, one is false :

Calcifications is one of the Degenerative changes

Increased proteoglycan has a role

Degenerative changes in the cardiac valves are probably an inevitable aspect of aging

Degenerative changes have no relation with congenital valves diseases

4 all of the following are correct regarding bicuspid aortic valve except :

Bicuspid aortic valve is the most common congenital valvular lesion

Containing only two functional cusps instead of the normal three

Bicuspid aortic valves are generally stenotic and incompetent through early life

Bicuspid aortic valve is more prone to early and progressive degenerative calcification that gives rise to stenosis.

5 All of the following are NOT match except :

Calcific aortic degeneration : most common cause of aortic stenosis

Bicuspid aortic valves : late Calcific aortic degeneration

Heaped-up calcified masses : Myxomatous Mitral Valve

Primary Myxomatous Mitral Valve : more in men

6 Myxomatous Mitral Valve, one is false :

One or both mitral leaflets are “floppy” and prolapse—they balloon back into the left atrium during systole

Myxomatous degeneration of the mitral valve is a common feature of Marfan syndrome

On histologic examination, the essential change is thickening of the valve layer known as the fibrosa layer of the valve

Secondary myxomatous change presumably results from injury to the valve myofibroblasts, imposed by chronically aberrant hemodynamic forces.

7 regarding Infective Endocarditis which is false :

Vegetations composed of thrombotic debris and organisms are formed

The vast majority of cases are caused by extracellular bacteria.

Acute endocarditis refers to infections by organisms of high virulence

50% to 60% of cases occurring on damaged or deformed valves are caused by S. aureus

8 the most common site/s of infection of IE :

Lift-sided valves

Tricuspid valve

Pulmonic valve

Mitral valve

The attached photo represent which of the following :

1. Osler’s lesion

2. Splinter hemorrhages

3. Roth spots

4. Vegetations of strep. Viridance
