Question 1: What two things are a sound waves wavelength determined by?

Answer:

The medium and the source of sound Question 2: What abnormality is present when the heart tube loops anterior and leftward?

Answer:

L-transposition or ventricular inversion.Question 3: In an emergency situation what body fluids may be considered infectious? How do you disinfect an area after a blood spill?

Answer:

All fluids may be infectious. After a blood spill put on your gloves, then use 1 part bleach with 10 parts water

Question 4: Describe normal aortic valve anatomy? Describe the

Sinus of Valsalva?

Answer:

There are three cusps, the right, left and the non coronary cusp. Behind each leaflet the wall dilates to form a sinus of valsalva. The L and RT sinus fill with blood during diastole. Respectively-RT Ao cusp to

the RT coronary artery and Left Ao cusp to t Question 5: What is the frequency of ultrasound? What is the frequency of Infrasound?

Answer:

Ultrasound is >20,000 Hz, Infrasound <20Hz.Question 6: What is the best reliable predictor for echo in a tamponade? What is a common way to treat a tamponade?

Answer:

RV wall diastolic collapse. Pericardial centesis(Tap) to drain the fluid

Question 7: Define Left ventricular diastolic dysfunction (DD) ?

Answer:

Left ventricular diastolic dysfunction is defined as the inability of the ventricle to fill to a normal end-diastolic volume, both during exercise as well as at rest Question 8: What is Ebstein's Anomaly? What are three common findings in patients with this anomaly?

Answer:

Apical displacement of the TV leaflets. TV abnormal, RVVO, ASD Question 9: Which would Endocarditis most likely cause, PI or PS? Which is a better role in evaluation of Infective endocarditis Transthoracic or Transesophageal Echo, Why?

Answer:

PI.Transthoracic echocardiography has proven to be useful for the diagnosis of infective endocarditis.However,suboptimal images in up to 20% of patients, limited image resolution, reduced ability to detect perivalvular abscesses in both native and prosth

Question 10: What is collateral circulation?

Answer:

Collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge an

Question 11: What walls are seen in apical 2 chamber view?

Answer:

Apical two-chamber view: The left ventricle (LV) and the left atrium (LA) can be displayed. In the two chamber view you can see the (septal side) which is called the Inferior Wall. Also, the Anterior Wall can be seen Question 12: In an aortic pressure recording, a gradual upstroke with a prominent

low anacrotic notch is indicative of:

• Aortic stenosis
• Aortic insufficiency
• Left ventricular failure
• Congestive heart failure

Answer:

• Aortic stenosis

Question 13: What does the term "BART" stand for in ultrasound?

Answer:

This is the standard direction of blood flow in orientation to the transducer.(Blue-away, red-toward)

Question 14: What type of doppler uses autocorrelation?

Answer:

Color flow doppler Question 15: How many pulmonary veins are there? How do the pulmonary veins connect to the systemic circulation? What echo view is best for viewing the pulmonary veins?

Answer:

There are 4 pulmonary veins. The oxygenated blood leaves the lungs through pulmonary veins, which returns it to the left heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the bicuspid valve(MV), into th

Question 16: Can slow wall Mitral annular velocities be assessed

with Tissue Doppler?

Answer:

Mitral annular velocities examination.Slow wall velocities can be assessed with Tissue Doppler Imaging (TDI). The sample volume, when placed at the medial mitral annulus, shows slower velocities as when placed at the lateral annulus. The E/E' relationsh

Question 17: What are two ways to reduce bioeffects on an ultrasound system?

Answer:

Limit scan exposure time and reduce the transmit gain

Question 18: In the fetal heart what does the Bulbus Cordis form?

Answer:

LV and RV, The bulbus cordis (also known as the conotruncus) lies ventral to the primitive ventricle after the developing heart assumes its S-shaped form. Together, the bulbus cordis and the primitive ventricle give rise to the ventricle of the formed hea Question 19: 1)Which of the following coronary arteries provides blood to the anterior wall of the left ventricle? 2)Which to the right ventricle? 3)Which to the inferior septal walls in a right dominant system?

Answer:

1)LAD-(Left anterior descending), 2)Right coronary, 3)Posterior descending

Question 20: What unit is dynamic range measured in? What is dynamic Range?

Answer:

Decibels, The range of gray scale between the lowest and the highest magnitude signals the ultrasound system can detect Question 21: The resistance(pressure build up) the ventricles face as they eject blood is called?Blood Pressure is mainly determined by? Increasing the _____ will cause a decrease in Cardiac Output

Answer:

Afterload, Afterload, Afterload causes a decrease in CO do to the increase in resistance
