A 42 year old female patient presents with a history of amyloidosis. You note that the E/A ratio is 2.3 and the E/e is 16. A respirometer is utilized to evaluate for any change in velocity in the mitral inflow. No change in either E or A velocity is appreciated. This filling pattern in consistent with: correct answer: restriction Dobutamine stress echocardiography in a 75-year-old patient reveals no wall motion abnormalities during the rest time period. During acquisition of the peak-dose images, a wall-motion abnormality is noted in the basal and mid-inferior segments of the apical two-chamber view. The most likely diagnosis is hemodynamically significant stenosis in the: correct answer: Right coronary artery A wall-motion abnormality is noted in the mid and apical segments of the basal and mid-inferolateral segments.
