Many #VExUS enthusiasts asked for a #tweetorial on image acquisition pearls. Did one b4 but time for an updated one 🧵

#1 Let's start with basics
Color Doppler identifies the flow + tells the direction (blue is away & red towards the probe [BART]) #2 👆BART holds good unless u invert the scale.
👇Pulsed wave Doppler (PWD) depicts blood flow at a certain point (sample volume) - we analyze the pattern of flow + velocity using this mode.
Above-the-baseline = flow towards the probe (like red on color)
Below = away (like blue)

Answer:
Dilated coronary sinus with a mobile echogenicity (vegetation/infective endocarditis in this case)
Full case: 🔗ncbi.nlm.nih.gov/pmc/articles/P…
From #POCUS standpoint, 2 main causes: persistent left superior vena cava & pulmonary HTN. This pt had the former.

One of my favorite topics in #POCUS - various effusions seen from different sonographic windows.

@Rajiv_Sinanan @ThinkingCC 1/ Real reason(s) based on my conversations with people from different backgrounds:
Private practice: "#POCUS sounds interesting but I ain't got time for that. Will consider if I get compensated"
Academia: (not generalizing but most places)
Emphasis is on funded research @Rajiv_Sinanan @ThinkingCC 2/ Clinical faculty are hired for clinical duties, outreach dialysis etc., which is fair but the problem is educational endeavors are rarely rewarded/provided with protected time. Faculty who want to be #POCUS champions must first learn it (either from institutional experts or
