Which factors predispose valves to pathology?
contain lymphoid tissue
The aortic valve has 3 cusps, right, left and . Each cusp has which is important for flow. Common pathology includes aortic and aortic .
Aortic stenosis can be , rheumatic valve disease, , calcification of trileaflet >
In bicuspid aortic valves- the primary issue is?
disruption to annulus
With calcific aortic "wear and tear", leads to lipids, inflammation, calcification. This the cusps. You can have loss of % with no symptoms. The sequelae is obstruction to flow which increases the load of the . The LV adapts by . Once symptoms occur average survival is years. The only effective treatment is .
In aortic regurgitation blood leaks back from the aortic root into the left ventricle. Abnormalities include congenital disease, rhematic heart disease, endocarditis and trauma. The primary pathology occurs during diastole. Distortions to the aortic root occur with HTN, Marfans, ankylosing spondylitis, syphilis, and aortic dissection. What is the compensation of the heart?
Increased LV end-diastolic pressure
Eccentric LV hypertrophy
Concentric LV hypertrophy
Decreased Stroke volume
Widened pulse pressure
The mitral valve has how many leaflets?
Mitral regurgitation can occur due to?
LV muscle /wall
During mitral regurgitation endocarditis destroys cusps
blood vessels( cusps, myocardium, blood vessels ) and ruptures chordae. Rheumatic valve disease leads to scarring and retraction. Mitral valve prolapse
hypertrophy( prolapse, stenosis, hypertrophy ) occurs by expansion and elongation. Papillary muscle are affected during infarction
birth( infarction, ischaemia, birth ).
Which of these are common symptoms of acute mitral regurgitation?
Increased L ventricle pressure
Increased L atrial pressure
Decreased Cardiac Output
In chronic mitral regurgitation there is left ventricle concentric hypertrophy?
Rheumatic stenosis takes to develop. It leads to valves, of commissures, and thickened . Left pressure rises, and pulmonary is common. Mitral stenosis can be treated by surgery involving valve replacement and .
Susceptibility to infective endocarditis involves?
IV drug users
Endocarditis complications include?
