120 CORRECTLY ANSWERED Quizzes.
what are the 2 atroventricular valves? - ANSWER- mitral., & tricuspid
what are the 2 semilunar valves? - ANSWER- aortic., & pulmonic
stenosis., - is Constriction or narrowing; creating a pressure difference, which increases
after-load. - ANSWER- regurgitation., - is Incompetence or insufficient; causing
incomplete closure of the valve that results in back-flow of blood., which increases pre-
load.
what are the Risk factors for valvular diseases? - ANSWER- rheumatic heart disease,
myocardial infarction (MI)., congenital heart defect: bicuspid., valve., aging., &
congestive heart failure (CHF)
Children = congenital - ANSWER- Adults = degenerative
what is the Patho of valvular diseases? - ANSWER- Blood volume & pressures are
reduced in front of the affected valve & increased behind the affected valve.,
valvular diseases Result in Heart Failure., & All have a characteristic murmur -
ANSWER- .
what is the Patho of a mitral stenosis valvular condition? - ANSWER- Decreased blood
flow into the left ventricle leads to Left atria hypertrophy., that leads to Pulmonary
pressure increasing., which leads to Pulmonary hypertension., & leads to decreased
Cardiac Output
Mitral Valve Stenosis signs & symptoms: cause: rheumatic fever - ANSWER- .
what are the signs & symptoms of Mitral Valve Stenosis? - ANSWER- rheumatic fever.,
dyspnea on exertion., a. fib., Mitral Valve murmur., & Later: right Heart Failure
what arrhythmia is common with Mitral Valve Stenosis? - ANSWER- a. fib
what is the treatment for Mitral Valve Stenosis? - ANSWER- valvuloplasty (good with
the elderly)

what is the Patho of Mitral regurgitation valvular disease? - ANSWER- Back-flow of
blood into the left atria during systole., leads to Left atria dilation & hypertrophy., that
leads to Pulmonary congestion., which leads to Right ventricle failure., which leads to
Left ventricle dilation & hypertrophy to accommodate increased pre-load & decreased
cardiac output
what are the signs & symptoms of Mitral Valve regurgitation? - ANSWER- thready
pulse., cool extremities., Symptoms of left Ventricle failure., S. 3 heart sound., & Mitral
valve regurgitation murmur
Acute Mitral valve regurgitation leads to pulmonary edema. - ANSWER- Chronic Mitral
valve regurgitation leads to Left atrial enlargement and ventricular hypertrophy which
leads to decrease in cardiac output
what is the treatment for Mitral Valve regurgitation? - ANSWER- MitraClip Repair
Mitral Valve Prolapse., - is a type of regurgitation., - Like a door over-closing -
ANSWER- .
what are the signs & symptoms of Mitral Valve Prolapse? - ANSWER- Most often
asymptomatic., Click Murmur., Chest pain not resolved by nitroglycerin (NTG).,
supraventricular tachycardia (SVT) or ventricular tachycardia (VT) may develop., & an
Increased risk for endocarditis
what is the Patho of Mitral Prolapse Valvular condition? - ANSWER- Most common type
in the U.S., Abnormal Leaflet, papillary muscle, or chordae leads to mitral insufficiency
what Causes Mitral Prolapse? - ANSWER- Unknown., but Females are 2 times more
common than males
what are the complications of Mitral Valve Prolapse? - ANSWER- Mitral Valve
regurgitation., Infective endocarditis., Sudden death., & Cerebral Ischemia
Mitral Prolapse valvular condition., - May or may not have chest pain., Chest pain
episodes happen in clusters, especially during stress., Pain may include dyspnea,
palpitations, syncope., Does Not respond to anti-anginal., Mid-Systolic click., &
transesophageal echocardiogram (TEE) - ANSWER- .
what is the Patho of Aortic Stenosis valvular disease? - ANSWER- Increases after-
load., Incomplete emptying of Left atria., Left ventricle hypertrophy., Decreased cardiac
