Valvular disease

QuestionAnswer
what two things do valve disorders place patients at risk for? increased clot formation and increased risk for infection
the two, normal heart sounds heard during systole and diastole are called? lub and dub
the first sound is heard at the beginning of the systole with the closure of what two valves? tricuspid and mitral valve
the second sound is heard during the beginning of diastole with the closure of what two valves? pulmonary and aortic valve
stenosis narrowing - which leads to increased resistance to back flow and blood backs up
regurgitation/ insufficiency loose valve which leads to leakage of blood flowing backwards
the two most common valve disorders are mitral and aortic stenosis
murmurs are sounds heard due to turbulent blood flow through the heart or great vessels
physiologic murmurs innocent or functional, heard during states of high blood flow in heart (stress, fever, pregnancy), usually doesn't cause symptoms and will goes away
pathologic murmurs caused by valve deformity or dysfunction, may result in hemodynamic consequences, medical intervention needed
what are complication a patient may develop if they have a valvular disorder dysrhythmias, thrombus formation, stroke, MI, heart failure
what are some common causes of valvular disorders acquired causes -- atherosclerosis, hypertension, rheumatic disease congenital malformations - marfan syndrome
what is the major cause of rheumatic heart disease rheumatic fever
the gold standard for diagnosing a valvular disorder is what? echocardiography
TTE most commonly used: noninvasive, transducer placed on chest wall
TEE transducer inserted into esophagus, more sensitive, sedation required, used to see stuff better
common causes of mitral stenosis rheumatic fever & mitral annular calcification
what is occurring at the valve during mitral stenosis narrowing of the mitral valve
where is fluid backing up in mitral stenosis in the LA
symptoms of mitral stenosis pulmonary edema
common cause of mitral regurgitation following myocardial infarction
what is occurring at the valve during mitral regurgitation? the valve cannot close
where is fluid backing up during mitral regurgitation LA
symptoms of mitral regurgitation confusion, weakness, cool extremities, low urine output
common causes of aortic stenosis aortic sclerosis, RHD, congenital valve defect
what is occurring at the valve during aortic stenosis difficult for LV to eject blood because of high resistance
where is fluid backing up during aortic stenosis LV into LA
symptoms for aortic stenosis confusion, weakness, cool extremities, low urine output
common causes for aortic regurgitation aortic sufficiency
what is occurring at the valve during aortic regurgitation poor closure of aortic valve during diastole
where is fluid backing up in aortic regurgitation LV into LA
symptoms for aortic regurgitation confusion, weakness, cool extremities, low urine output
common causes for pulmonic stenosis pulmonary hypertension (working against the lungs)
what is occurring at the valve during pulmonary stenosis narrowing of pulmonic valve
where is fluid backing up during pulmonic stenosis RV into RA
symptoms of pulmonic stenosis symptoms of right HF
common causes of tricuspid stenosis infective endocarditis (IV drug use)
what is occurring at the valve during tricuspid stenosis narrowing of tricuspid valve
where is fluid backing up during tricuspid stenosis RA into vein
symptoms for tricuspid stenosis symptoms of right HF
