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 Marfa ns syndrome Correct 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 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 o f 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 vasov agal 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 symptoms related to an anaphylactic response. Because the short time frame between contr ast 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 and anaphylaxis caused by contrast injection? Hypertension is a sign of vasovagal response, while hypotension is a sign of anaphylaxis. Tachycardia i s 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. Correct 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 s eptum Correct 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 myoca rdium 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 Pompe disease is an autosomal recessive disorder that causes the abnormal storage of glycogen in the myocardial tissue. It causes increased ventricular thickening.
