Valves Flashcards
Orifice of valve narrows
Causes resistance to blood flow from left ventricle to aorta
Which disorder
Aortic stenosis
Resistance to blood flow from left ventricle into aorta
Which disorder
Aortic stenosis
Outflow obstruction increases pressure within the left ventricle as it tries to eject blood through narrowed opening
Which disorder
Aortic stenosis
Left ventricular hypertrophy develops to compensate for the increased workload
Which disorder
Aortic stenosis
Complications of which disorder
Hypertrophic cardiomyopathy
Myocardial ischemia or infarction
Oliguria
Stroke
Heart failure
Pulmonary edema
Aortic stenosis
Which disorder
Impairs the flow of blood from the left atrium to the left ventricle
Mitral stenosis
Which disorder
Results in incomplete emptying of the left atrium and elevated atrial pressure
Mitral stenosis
Complications of which disorder untreated
Pulmonary hypertension
Edema
Right ventricular failure
Mitral stenosis
Which disorder
Permits backflow of blood from left ventricle into left atrium during ventricular systole
Mitral regurgitation
Backflow of blood from left ventricle into left atrium
Mitral regurgitation
Which disorder happens during ventricular systole
Mitral regurgitation
Left ventricular function may become impaired to the point of failure
Which disorder
Mitral regurgitation
Eventually increased atrial pressure causes pulmonary hypertension and failure of the right ventricle
Mitral regurgitation
Which two valve disorders cause pulmonary hypertension and RV FAILURE
Mitral stenosis
Mitral regurgitation
Which disorder is associated with connective tissue disorders like Marfan syndrome?
Mitral regurgitation
Left ventricular hypertrophy seen with which valve disorder
Aortic stenosis
Most common form of valvular heart disease
Aortic stenosis
Narrowing of what valve narrowing hinders blood flow into the aorta decreasing arterial circulation and coronary circulation
Aortic stenosis
Valve stenosis of what increases the resistance against the left ventricle making the left ventricle hypertrophy
Aortic stenosis
What valve disorder
Leakage of blood into the left atrium, backward into the pulmonary veins and pulmonary capillaries
Mitral regurgitation
Left atrium dilated due to back flow of blood
What disorder
Mitral regurgitation
There’s too much flowing from the left ventricle into the left atrium! I can’t accommodate all this backflow!
Mitral regurgitation
Obstructs blood flow from the left atrium to the left ventricle
What disorder
Mitral stenosis
