When distinguishing between mediastinal fat and cardiomegaly, fuzzy margins and a more radiolucent area surrounding the heart indicate cardiomegaly.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 8 von 22

1

Which of the following is FALSE?

Wähle eine der folgenden:

The cardiac silhouette may be enlarged without heart enlargement. This occurs commonly in obese animals where fat is deposited in the pericardium.
Athletic dogs may have slightly larger hearts.
Puppies appear to have larger hearts relative to their body size.
Radiographs help distinguish between dilation and hypertrophy.
Breed conformation causes a tremendous variation in cardiac shape and size.

Erklärung

Frage 9 von 22

1

Which of the following indicate right heart enlargement? Check all that apply.

Wähle eine oder mehr der folgenden:

Enlargement of dorsocaudal border
Dorsal deviation of entire trachea (parallel to spine)
May see caudal bronchi compression
Caudal heart border elongated and upright
Increased width of heart
Increased sternal contact
Elevation of apex
Elevation of trachea if severe

Erklärung

Frage 10 von 22

1

Right heart enlargement in a cat looks like a Valentine's heart.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 11 von 22

1

Which of the following is FALSE about congenital heart disease?

Wähle eine der folgenden:

Almost all patients have a cardiac murmur
Absence of clinical signs at the time of detection is typical and implies good prognosis
Some lesions can be corrected but are associated with high mortality if untreated
Definitive non-invasive diagnosis requires Doppler echocardiography

Erklärung

Frage 12 von 22

1

Congenital heart disease may cause a soft murmur but a loud one always indicates the presence of disease.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 13 von 22

1

Which of the following is TRUE of therapy of congenital heart disease?

Wähle eine der folgenden:

CHD is most appropriately treated by medical therapy
All surgical approaches (not including interventional catheterization) require cardiopulmonary bipass
Interventional catheterization is nearly as invasive as surgeries
Some forms of CHD can be treated definitively

Erklärung

Frage 14 von 22

1

Which of the following is FALSE about PDA?

Wähle eine der folgenden:

One of the most common forms of CHD in dogs
If a murmur is truly continuous, PDA is almost always the cause
PDA imposes volume overload on the right atrium and right ventricle, therefore right-sided CHF is a potential consequence
Mortality is high without correction. Transcatheter occlusion or surgical ligation represent definitive management

Erklärung

Frage 15 von 22

1

Which of the following describe pulmonic stenosis? Check all that apply.

Wähle eine oder mehr der folgenden:

Imposes a pressure overload on the right ventricle
Severely affected dogs may develop and succumb to right-sided CHF in the first years of life despite a lack of clinical signs during puppyhood
Definitive diagnosis requires Doppler ECHO
Initial treatment of choice is balloon valvuloplasty
A common malformation most often in large breed dogs
Imposes a pressure overload on the left ventricle
Definitive diagnosis requires M-mode ECHO
Severely affected dogs are more likely to die suddenly than to develop CHF
Management options are few, beta-blockade may be palliative

Erklärung

Frage 16 von 22

1

Isolated ventricular septal defects cause a diastolic murmur, shunts left to right and imposes a volume overload on the left atrium and left ventricle. Most VSD in small animals is severe with significant clinical consequences.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 17 von 22

1

Which of the following describe concentric hypertrophy? Check all that apply.

Wähle eine oder mehr der folgenden:

Hypertrophy associated with normal chamber dimensions
Hypertrophy associated with chamber dilation
Consequence of pressure overloads
Consequence of volume overloads

Erklärung

Frage 18 von 22

1

Which of the following is FALSE regarding atrial septal defects?

Wähle eine der folgenden:

A left-to-right ASD imposes a volume load on the right atrium and ventricle
If present, a murmur results from "functional pulmonic stenosis" not the shunt itself
ASDs are relatively uncommon
Can be repaired per-catheter using an occluding device or surgically under cardiopulmonary bypass
All of the above are true
All of the above are false

Erklärung

Frage 19 von 22

1

Which of the following is FALSE regarding AV valve dysplasia?

Wähle eine der folgenden:

Can result in regurgitation or stenosis
Relatively common in cats
Tricuspid valvular dysplasia is relatively common in labradors
Severity is often mild
Regurgitation as a result of dysplasia requires cardiopulmonary bypass for correction

Erklärung

Frage 20 von 22

1

Cyanotic heart disease results when there is a shunt at one of the following: tricuspid stenosis, severe pulmonic stenosis, pulmonary hypertension associated with elevated pulmonary vascular resistance.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 21 von 22

1

Eisenmenger's Physiology states that decreased pulmonary blood flow can result in vascular disease, a drop in pulmonary vascular resistance and shunt reversal.

Wähle eins der folgenden:

WAHR
FALSCH

Erklärung

Frage 22 von 22

1

Tetrology of Fallot is an uncommon cyanotic heart disease. Pulmonic stenosis, ventricular septal defect, right ventricular hypertrophy, and aortic malposition are all present. Definitive repair is under cardiopulmonary bypass. Phlebotomy/beta-blockade may be palliative.
