Valve insufficiencies Flashcards
With mitral valve insufficiency the valve is unable to maintain _______ blood flow between left atrium and left ventricle, which results in ______ overload in the left atrium and ______ hypertophy of the left ventricle.
unidirectional
volume
eccentric
Mitral Valve insufficiency ultimately progresses to ____-____ congestive heart fail and sometimes ____-____ heart failure. The most common valvular disease in adult dogs of ALL breeds older than ____ years. (Aquired MV insufficiency is uncommon in cats). It is mostly caused by ______.
left-sided
right-sided
5
endocardiosis
With Mitral Valve insufficiency a ______ heart murmur can be heard at PMI ___ or ___ intercostal space which increases with intensity over time but may not correlate with the severity of _______ changes. Clinical signs are usually absent unless ____ ____ failure occures resulting in moist cough, ______ (or fast heart rate), restlessness at night, panting, exercise intolerance, dyspnea and synocpe. The cough may be do to _____ _____ due to enlargement of the left atrium) rather than by heart failure. Animals with _____ chordae tendinae or papillary muscle may present in _____ cardiac decompensation.

acute
The ____ ____ enlargement often is the only finding with early or mild mitral insufficiency. Over time, the _____ _____ can become largely dialted. The ____ ____ enlarges in more severecases. Severe dialation of the ____ ____ can result in tearing of the atrial wall and hemorrhage into the _____ ____ causing a _____ effusion.

Other names for Mitral Valve Insufficiency are?
DDFs for Mitral Valve insufficiency?
Chronic mitral valve disease
mitral valve regurgitation (or incopetence)
Mitral valve stenosis (rare)
Endocarditis
What are some other names for Tricuspid Valve Insufficiency?
What are some DDFs?
Tricuspid regurgitatoin
Right heart failure is rare unless a more severe dz is present (HW, cardiomyopathy, endocarditis)
Tricuspid vavle insufficiency means the tricuspid valve is unable to maintain ______ blood flow between the right atrium and the right ventricle. It is more common in older ____ and uncommon in ____. It usually occurs secondary to ____ _____ insufficiency. (Isolated tricuspid insufficiency is rare).
unilateral
dogs
cats
mitral valve
A bilateral ____ heart murmur may be heard with tricuspid valve insufficiency due to concurrent mitral insufficiency, but would be loudest (PMI) over the ___ to ____ intercostal space. Clinical signs are usually absent unless ____ ____ failure occurs, resulting in ______ abdomen.
systolic
3rd to 5th
Right Heart
distended
(hepatomegaly and ascites), exercise intolerance and dyspnea (pleural effusion)
Enlargement of the ____ ____ causes the cranial border of the cardiac silhouette to bulge forward (lateral rad) and expansion of the right craninal caridc boarder (DV/VD rad). ____ ____ insufficiency is usually concurrent, resulting in generalize ______.
right atrium
Mitral valve
cardiomegaly
