ABCP REVIEW EXAM 2023 WITH 100% CORRECT ANSWERS

Which of the following is not true regarding peak aortic blood flow acceleration? a) it is significant primarily in patients with aortic stenosis b) it is a sensitive indicator of changing contractility state and secondary to hypoxia c) it is highly sensitive to inotropic changes d) it is minimally affected by preload changes e) 2 of the above - correct answer it is significant primarily in patients with aortic stenosis In doppler assessment of aortic valve gradient: a) the degree of stenosis is better indicated by the peak gradient than the mean gradient as it is less flow dependent b) patients with coexisting aortic insufficiency may have higher gradients for the same degree of stenosis than patients with pure aortic stenosis c) the result is not very accurate as it cannot be directly measured and must be calculated using a simplified bernoulli equation d) 2 of the above e) all of the above - correct answer patients with coexisting aortic insufficiency may have higher gradients for the same degree of stenosis than patients with pure aortic stenosis Which of the following statements is false regarding echocardiography? a) surface echo is an excellent method of detecting the amount of normal ventricle remaining in a patient with a left ventricular aneurysm b) TEE is a much more accurate method of evaluating a descending thoracic aneurysm than is surface echo c) As 70% of ascending dissections arise in the proximal area, surface echo is a good diagnostic tool for these cases d) echocardiography is of little value in diagnosing sinus of valsalva aneurysms as the view of this anatom
