Quiz zum Vortrag
How does blood flow across a valve change with valvular stenosis vs. valvular insufficiency?
- Stenosis impedes forward flow; insufficiency allows backward flow.
- Stenosis increases forward flow; insufficiency allows backward flow.
- Stenosis impedes forward flow; insufficiency impedes backward flow.
- Stenosis allows backward flow; insufficiency impedes forward flow.
- Stenosis impedes forward flow; insufficiency increases forward flow.
What is valvular functional regurgitation?
- Failure of coaptation of the valve leaflets without structural changes in the valve itself
- Valvular stenosis due to calcifications
- Valvular incompetence after surgery
- Failure of coaptation of the valve leaflets due to a defect in the valve itself
- Valvular incompetence due to infective endocarditis
How does the heart compensate for valvular stenosis vs. valvular insufficiency?
- Valvular stenosis >> pressure overload >> concentric hypertrophy Valvular insufficiency >> volume overload >> eccentric hypertrophy
- Valvular stenosis >> volume overload >> eccentric hypertrophy Valvular insufficiency >> pressure overload >> concentric hypertrophy
- Valvular stenosis >> pressure overload >> eccentric hypertrophy Valvular insufficiency >> volume overload >> concentric hypertrophy
- Valvular stenosis >> volume overload >> concentric hypertrophy Valvular insufficiency >> pressure overload >> eccentric hypertrophy
- Valvular stenosis >> pressure overload >> concentric hypertrophy Valvular insufficiency >> pressure overload >> concentric hypertrophy
Which of the following factors does NOT significantly impact the clinical course of valvular heart disease?
- Family history of heart disease
- Valve involvement
- Degree of valve impairment
