Quiz
Degenerative Mitral Valve Disease (DMVD) is
(Required)
A congenital disorder that occurs frequently in giant breeds
An acquired disease affecting mainly small breed dogs
An inflammatory disease secondary to periodontitis
Stage B2 DMVD means that
(Required)
There is minimal mitral regurgitation and no cardiac enlargement
There is left atrial and ventricular enlargement secondary to DMVD that is severe enough to meet the criteria used to identify dogs that profit from initiation of medical therapy that can delay the onset of congestive heart failure
End stage DMVD
Stage C DMVD includes
(Required)
Patients with past or present clinical signs of heart failure due to DMVD
Patients at risk for developing DMVD but without present structural or functional cardiac abnormalities
Patient with DMVD and mitral regurgitation but without evidence of cardiac enlargement
Hemodynamically significant mitral regurgitation causes
(Required)
Left sided volume overload
Left sided pressure overload
Right sided volume overload
Risk factors in dogs with DMVD for the development of CHF are
(Required)
Progressing left ventricular and left atrial volume overload
E-waves < 0.8 m/s
Severe valvular changes
An inverse E/A-ratio on mitral inflow profiles (E wave smaller than A wave)
(Required)
Means that the patient is very likely not in CHF
Means that the patient is very likely in CHF
Does not exist in dogs
Left ventricular dimensions can be normalized by body weight using the
(Required)
Cornell-Index
Kittleson-Index
Atkins-Index
Mitral valve prolapse
(Required)
Means that the free edges of a mitral valve leaflet overtop the mitral annular plane
Can be caused by chordal elongation or chordal rupture
Occurs frequently in dogs with DCM
Correct echocardiographic assessment of morphology, dimensions, and function in dogs with DMVD
(Required)
Does not make a difference and is therefore not necessary
Does not have any influence on treatment decisions
Is very important to guide appropriate treatment and monitoring
Surgical treatment of DMVD
(Required)
Is today a realistic option for patient suffering from advanced disease
is a purely experimental procedure and not a realistic option for patients suffering from DMVD
requires a trained and skilled team consisting of surgeons, anesthesiologists, and perfusionists
