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
