The peak velocity of aortic regurgitation indicates the maximum pressure gradient between:
the aorta and the LV in systole
the aorta and the LV in diastole
the LV and the LA in diastole
the LV and the LA in diastole - CORRECT ANSWER -the aorta and the LV in diastole
Which type of image resolution improves with proper placement of the focal zone at the area of interest?
temporal
lateral
contrast
elevational - CORRECT ANSWER -Lateral
The tissue of the interventricular septum will be best visualized when:
the US beam is parallel to the long axis of the septum
the US beam is perpendicular to the longyaxisyof the septu
the dynamic range is increased
harmonics is turned off - CORRECT ANSWER -the USybeam is perpendicular to the long axis of the septum
A 38yr old male presents for an echo due to a systolic murmur and has no other cardiac symptoms. Due t
o patient habitus, 2D imaging is significantly limited but the EF% appears normal. The aortic valve velocity
is 4m/s with a peak pressure gradient of 64mmHg and no aortic insufficiency is detected. Which of the fol
lowing is the most likely etiology of the aortic stenosis?
,bicuspid AV
infective endocarditis
degenerative disease
Marfans syndrome - CORRECT ANSWER -bicuspid AV
All of the followingyare evaluated on a cardiac MRI, except:
regurgitant volume of mitral regurgitation
left ventricular mass
mitral valve prolapse
left ventricular systolic volume - CORRECT ANSWER -mitral valve prolapse
Cardiac MRI cannot demonstrate the fine structures and motion of the valves.
You are performing a resting echo with contrast for wall motion evaluation. Just after the injection of micr
obubble contrast, the patient complains of feeling short of breath and their face appears to be flushed. Th
e heart rate on the EKG is 117bpm. Which of the following correctly describes their symptoms?
the patientyis most likely experiencingya vasovagal reaction to the contrast
this is a normal response to perfluorocarbon contrast media
the symptoms are most likely related to anxiety
,the patient is most likely experiencing an anaphylactic reaction to the contrast - CORRECT ANSWER -
the patient is most likely experiencing an anaphylactic reaction to the contrast
Tachycardia, bronchospasm, wheezing, pruitis, erythema, hives and a feeling of impending doom are sym
ptoms related to an anaphylactic response. Because the short time frame between contrast injection and
the symptoms, the most likely cause of the symptoms is an allergic reaction.
Flattening of the IVS is least likely to be associated with which of the following?
3mm muscular VSD
Congestive heart failure
Large ASD
Pulmonary HTN - CORRECT ANSWER -3mm muscular VSD
Which of the following correctly describes the way to tell the difference between a vasovagal response an
d anaphylaxis caused by contrast injection?
Hypertension is a sign of vasovagal response, while hypotension is a sign of anaphylaxis.
Tachycardia is a sign of vasovagal response, while bradycardia is a sign of anaphylaxis.
A feeling of impending doom is a sign of vasovagal response, while dizziness and near syncope are signs o
f anaphylaxis.
Pallor is a sign of vasovagal response, while erythema is a sign of anaphylaxis. -yCORRECT ANSWER -
Pallor is a sign of vasovagal response, while erythema is a sign of anaphylaxis.
The right coronary artery supplies which of the following with blood?
, LV anterior wall
LV apex
ventricular septum
interatrial septum - CORRECT ANSWER -interatrial septum
The right coronary artery supplies the RV free wall, RV apex, inferior LV wall and interatrial septum with bl
ood.
All of the followingydescribe Pompe disease, except?
type of infiltrative disease of the myocardium
involves abnormal storage of glycogen in the muscle tissues
autosomal recessive disease
involves abnormal storage of fat in the muscle tissues - CORRECT ANSWER -
involves abnormal storage of fat in the muscle tissues
