#echocardiography — Public Fediverse posts

I can't really tell if this is good news or bad news.

Good news perspective: for this pretty large cohort of mild acute SARS-CoV2 cases, cardiac damage was subclinical

Bad news perspective: for this pretty large cohort of mild acute SARS-CoV2 cases, cardiac damage was quite detectable by imaging.

All participants were putatively healthy, none had moderate or severe COVID-19.

"In the present cohort of COVID-19-infected individuals with mild initial illness, echocardiographic measurements revealed significant yet subclinical differences in systolic and diastolic function compared with controls, as well as between individuals with cardiac symptoms and those without. All the measured differences were small in magnitude and thus unlikely to be detectable clinically at the individual level." [1]

🖥️ Using #echocardiography to predict fluid-responsiveness & manage need for fluids in #ICU, bedside experience + literature based approach:
💧💧 when to fill??
☔️ when NOT to fill??
💦 optional filling... gray zone of #POCUS parameters
PS adequate training pivotal to avoid misinterpretation!!

I did a talk for cardiologists about #criticalcareecho, emphasising the difference between outpstient/normal data and the critical ill. Supeisingly well recieved and I’ll reiterate my main points:
- Most important use for echo in critical illness is differentiating shock types, and detecting “black swan” conditions like LVOT obstruction and acute valvular pathologies
- Always combine echo with clinical findings.

Interesting review of diastolic function grading in critically ill patients, basically arguing for left atrial strain. Some comments follow : https://onlinelibrary.wiley.com/doi/10.1111/echo.15773 #echocardiography #CriticalCare #cardiology

I see this assertion repeatedly made, but it cannot both be true that a measure is load indepenendent and that it also tracks left atrial pressure! #echocardiography #CriticalCare #CritCareEcho

Suspicion of #PFO in #ARDS: if agitated saline is injected through CVC located in the SVC, #TEE is required to rule out the diagnosis.

If #TEE shows the presence of an #Eustachian valve, injection in a catheter located in the IVC territory is required.

I have to say I miss the old #ASE #Echocardiography guideline app, but the #BSE app is a great replacement https://apps.apple.com/app/id468166426 #Cardiology

A very interesting paper evaluating the effect of correcting low preload in critically ill patients, appropriately pointing out that global longitudinal strain alone cannot be used in this cohort to diagnose cardiac dysfunction. Preload induced change in GLS follows change in CI. https://annalsofintensivecare.springeropen.com/articles/10.1186/s13613-018-0376-8

@strain_rate here’s one study showing how LA reservoir strain decreases in normal subjects as preload is reduced during a tilt manoeuvre #echocardiography #echofirst #Physiology https://www.sciencedirect.com/science/article/pii/S0894731718304048

Reposting this fasctinating study here that I shared last year, on the effects on RAP and PCWP of rapid fluid loading (100-200ml/min 1L + 1L warm NS), in a first in healthy younger and older (>50yo) subjects. Striking results, with marked increases in pressures despite absence of heart failure. #echocardiography #cardiology #CriticalCare #Physiology https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.112.111302

A good idea and its validation.

Because LVOT area is related to body surface area:

echoVTI x HR x k = indexed CO

Confusion between #AcuteCorePulmonale and #RightVentricularDysfunction is common in #ICU.

A very important reminder that anyone using #Echocardiography to assess #RightVentricularFunction in critically ill patients should read and share.

1st day of #adventarticles, sharing some of my all time favourite papers:
"Ejection Fraction Revisited" from Robotham et al, THE paper to read on ejection fraction.
One of many key takeaways:
Hyperdynamic LV/supranormal EF is not a sign of low preload, on the contrary EF is relatively preload insensitive and if anything very low preload lowers EF.

Excelent example illustrating that MAPSE, TAPSE and mitral/tricuspid annulus tissue doppler velocities aren’t representative and should not be trusted when apex is not stationary, a quite common finding not leat in RV dysfunction. #echocardiography https://twitter.com/argulian/status/1595125295904088064?s=46&t=FrtHdpb02j-3NH4Sj0Oq6A

Another trial of automated EF measurements, limits of agreement +- about 20% seems less than tolerable. Off course, always a question how much error there is in the reference standard too. #echocardiography #ai https://www.mdpi.com/2075-1729/12/9/1413/htm

#introduction to new instance!
I'm an end stage #cardiology trainee working in Trondheim, Norway, finishing up a PhD in #POCUS in stroke care, aiming to subspecialise in #cardiaccriticalcare and #imaging. Obsessed with #criticalcare #echocardiography, fascinated by #physiology and #statistics, concerned about the future of our #publichealthcare system, #socialdeterminantsofhealth and #climatechange

MPI aka Tei index is often described as an integrated index of systolic and diastolic function. In truth, this applies to pretty much any measure of cardiac function in #echocardiography. Diastole and systole are inextricably linked. #foamcc @[email protected]

#introduction Hi, I’m Lars, a late stage cardiology trainee in Norway finalising a PhD on #pocus in #stroke, and an aspiring cardiac intensivist.

Focused on general critical care and particularly heart failure, #physiology, multi organ ultrasound and critical care #echocardiography not least. My big pet peeve is the variable but inevitable load dependence of all echocardiographic measures of cardiac function, hence my handle😆.
