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 - 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 - 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 long axis of the septu the dynamic range is increased harmonics is turned off - Answer-the US beam 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 to 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 following is the most likely etiology of the aortic stenosis?bicuspid AV infective endocarditis degenerative disease Marfans syndrome - Answer-bicuspid AV All of the following are evaluated on a cardiac MRI, except: regurgitant volume of mitral regurgitation left ventricular mass mitral valve prolapse left ventricular systolic volume - 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 microbubble contrast, the patient complains of feeling short of breath and their face appears to be flushed. The heart rate on the EKG is 117bpm. Which of the following correctly describes their symptoms? the patient is most likely experiencing a vasovagal reaction to the contrast this is a normal response to perfluorocarbon contrast media the symptoms are most likely related to anxietythe patient is most likely experiencing an anaphylactic reaction to the contrast - 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 symptoms 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 - Answer-3mm muscular VSD Which of the following correctly describes the way to tell the difference between a vasovagal response and 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 of anaphylaxis. Pallor is a sign of vasovagal response, while erythema is a sign of anaphylaxis. - 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 wallLV apex ventricular septum interatrial septum - Answer-interatrial septum The right coronary artery supplies the RV free wall, RV apex, inferior LV wall and interatrial septum with blood. All of the following describe 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 - Answer-involves abnormal storage of fat in the muscle tissues Pompe disease is an autosomal recessive disorder that causes the abnormal storage of glycogen in the myocardial tissue. It causes increased ventricular thickening.If the peak velocity of the E wave on the mitral tracing is 1.2m/s and the tissue Doppler assessment of the septal annulus indicates a peak velocity of E' of 6cm/s, the LV diastolic filling pressures are ________________. decreased increased unable to be estimated without more information normal - Answer-increased 1.2m/s = 120cm/s E/E' = 120/6 = 20 E/E' 8 is normal, 15 indicates increased LV filling pressures All of the following correctly describe end diastolic pressure in the left ventricle, except: is normally at least 3X the right ventricular diastolic pressure it is elevated with moderate - severe aortic insufficiency it is equivalent to the mean left atrial pressure it is defined as LV preload - Answer-is normally at least 3X the right ventricular diastolic pressureLeft ventricular diastolic pressure is equivalent to the mean left atrial pressure. LV preload is defined as the diastolic pressure in the left ventricle. Significant AI will increase the diastolic pressure in the left ventricle. The diastolic pressure in the normal RV is usually less than 5mmHg below the LV diastolic pressure. Which of the following best describes the primary reason why the TEE probes are soaked in a disinfectant for a specified amount of time? Soaking the probe too long in a disinfectant solution can damage the bonding effect of the glue used to assemble the probes. Soaking the probe too long in a disinfectant solution will decrease the flexibility of the rubber coated portion of the probe causing cracks. Soaking the probe too long in a disinfectant solution will cause the disinfectant to be absorbed inside the probe and damage the electrical components. Soaking the probe too long in a disinfectant solution will degrade the imaging capabilities of the piezoelectric element. - Answer-Soaking the probe too long in a disinfectant solution can damage the bonding effect of the glue used to assemble the probes. _________________ adjusts the brightness of the entire image where ________________ adjusts the brightness of specific portions of the image. overall gain, output power monitor contrast, time-gain compensation post processing, pre processing overall gain, time-gain compensation - Answer-overall gain, time-gain compensationThe least common type of ASD seen in patients today is? - Answer-coronary sinus defect Septum Secundum: most common, mid septal area Septum Primum: 2nd most common, close to AV valves Sinus Venosus: near SVC entrance Coronary Sinus Defects: inferior portion of septum, rare
