Explicação

Questão 11 de 22

1

Which of the following is FALSE about congenital heart disease?

Selecione uma das seguintes:

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

Explicação

Questão 12 de 22

1

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

Selecione uma das opções:

VERDADEIRO
FALSO

Explicação

Questão 13 de 22

1

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

Selecione uma das seguintes:

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

Explicação

Questão 14 de 22

1

Which of the following is FALSE about PDA?

Selecione uma das seguintes:

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

Explicação

Questão 15 de 22

1

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

Selecione uma ou mais das seguintes:

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

Explicação

Questão 16 de 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.

Selecione uma das opções:

VERDADEIRO
FALSO

Explicação

Questão 17 de 22

1

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

Selecione uma ou mais das seguintes:

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

Explicação

Questão 18 de 22

1

Which of the following is FALSE regarding atrial septal defects?

Selecione uma das seguintes:

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

Explicação

Tricuspid valvular dysplasia is relatively common in labradors
Severity is often mild
Regurgitation as a result of dysplasia requires cardiopulmonary bypass for correction

Explicação

Selecione uma das opções:

VERDADEIRO
FALSO

Explicação

Questão 21 de 22

1

VERDADEIRO
FALSO

Explicação

Questão 22 de 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.
