For those with smartphones or iPads I recommend the following apps as excellent reference guides. The first is from the University of Toronto (same folks who brought you the Virtual TEE website) and the next 3 are from the American Society of Echocardiography

September 2017

September question: In the first video, a suprasternal TTE is done, with the accompanying CW Doppler trace (first image). The second video shows a short and long axis midesophgageal view. The third video is a view of the proximal descending-distal aortic arch in long and short axis. What are the diagnoses?

September answer: This is an example of an aortic coarctation. The first video and image come from a suprasternal TTE view with Doppler evidence of a fixed gradient. Video 2 shows a bicuspid aortic valve which often coexists with aortic coarctation. Video 3 shows a TEE with the descending aorta just distal to the left subclavian artery, with aliasing of CD at the site of coarctation.



Summer 2017

Summer question: A fun question for the summer. Those of you with kids will be familiar with the "Fidget Spinner". I have rotated the spinner CLOCKWISE and acquired a video at 30 fps. At the same rotational speed (rpm) video was acquired at 240 fps. In Doppler echocardiography, what are the frames per second (fps) analogous to, and what phenomenon is being illustrated?
