1/ Had a great time writing this @EPLabDigest article with @DrCJBradley

tinyurl.com/mryk3cwe

2️⃣ different perspectives (IC And EP) using different devices (watchman/ amulet) for LAAC in the community center.

Let’s take a dive into two different LAAC programs #Tweetorial

2/ #LAAC has come a long way over the past few years and now we have two main players in the space

🔸 @bostonsci #watchman
🔸 @AbbottNews #Amulet

Both are very effective and each has pros/cons

My center focuses on Watchman FLX while @DrCJBradley center focuses on Amulet… twitter.com/i/web/status/1…

3/ Historically #EPeeps has taken the driver seat in this space (rightfully so) due to experience with the LA/transeptal. HOWEVER the new gen #IC/structuralist have become a vital part of the team.

#LAAC programs require:
📌Implanter
🔎Imager
🧑🏼‍⚕️Anesthesiologist/Cath lab team… twitter.com/i/web/status/1…

When your ER colleague calls you to have a quick look on an #ecg … the 28 yo pat reports frequent episodes of palpitations since childhood that he can usually terminate with deep breathing. #Epeeps @EPeeps_Bot #CardioTwitter know what’s going on. Do’s and Don’t’s? twitter.com/i/web/status/1…

🫀⚡️CTI-Blockade bei rechtsatrialemp #Vorhofflattern war eine meiner ersten eigenen Prozeduren in der EP und bleibt bis heute eine faszinierende Untersuchung.

Doch wie war das nochmal mit dem Flattern und dem CTI - ein kleiner 🧵, nicht nur für #EPeeps

#FOAMed #CardioTwitter

Rechtsatriales Vorhofflattern basiert auf einem Makroreentry im rechten Vorhof und rotiert entweder gegen den ⏰ („typisches Vorhofflattern“) oder mit dem ⏰ um den Trikuspidalklappenannulus (TKA).

Der Begriff Makroreentry beschreibt eine kreisende elektrische Aktivierung rund um ein großes Hindernis, den TKA – schön zu erkennen im elektroanatomischen Map ⬆️👆🏻

Fabry's CM is an X-linked inherited deficiency of alpha-galactosidase A which results in systemic sphingolipid accumulation.
Severity of manifestation depends on degree of X-chromosome inactivation => female carriers can have a wide range of phenotypes! doi.org/10.1016/j.jcmg…

https://twitter.com/AJamilTajik/status/1618730060026093570

This 67 yo pt presented with severe HCM phenocopy and strong family history of confirmed Anderson-Fabry's CM. She was determined to have a GLA mutation and successfully started on treatment with Fabrazyme.

Note the diffuse asymmetric LVH (wall thickness 24mm) with marked apical hypertrophy (30mm). Despite normal LVEF, her GLS was markedly reduced at -5.8%. CMR demonstrated 20% LGE and short T1 time (indicative of fat accumulation)

This is the ff-up ECG. This is not SR. The 🔑 to rhythm dx is in the PRI (long lead). You need a caliper to 👀 the PR difference. If you have 🦅👀 the extra P can be 👀. So, the ECG case can be explained with 1 reason.

Great experience in my trip to Argentine.The audience was excited. We performed a live CNA case During my visit. Lots of questions arose during the case and my lectures. Here are some misunderstood tips in #Cardioneuroablation🚨Tweetorial alert. @drraviele @CarlChiefCard

1/10 Atropine blocks the effect of the vagus, by blocking muscarinic receptors, we can use it to predict the outcome of #Cardioneuroablation doi.org/10.1016/j.hrth…. @natale_md @mdTolgaAksu @Josefkautzner @piotrowskiroman @pachon_phd @scanav1mauricio @alfieep

2/10 AT is a great tool for the selection of patients, but its effect compromises the study through extra cardiac vagal stimulation #ECVS. We always use it prior to #CNA for patien selection.

Working with @seth_j_worley to create a reproducible, technically "easier" and systematic approach to #VeinofMarshall ethanol ablation for #EPeeps. Advance Preface sheath over CS decapolar catheter and then advance Amplatz Super Stiff to retain wire access.

Use the @MeritMedical Worley Coronary Sinus Guide Jumbo 50 cm size. The 9 Fr inner diameter is key to provide room to easily manipulate balloons, wires, inner guide catheters, etc. #VeinofMarshall is easily identified with RAO 20° cine projection.

The 5 Fr CS Vertebral shape vein selector easily advances through the 9 Fr @seth_j_worley Jumbo sheath to cannulate the #VeinofMarshall with a Boston Choice PT Floppy guidewire.

#EPeeps Brief 🧵 on beta blocker hyperkalemia which is unfamiliar to many

The mechanism is the opposite of why we use albuterol to treat hyperkalemia - beta receptor modulation of Na K ATPase, the sodium potassium exchange channel [1/]

See great diagram from @paulpengmdphd

Beta blockers rarely cause hyperkalemia in isolation, but can contribute in at-risk patients.

The patient who prompted this discussion (see link) had complex multi-system illness. Ectopy was exacerbated by diuretic-induced hypoK so had MRA + scheduled enteral KCl [2/]

https://twitter.com/jeffrey_vinocur/status/1579316779301580800

One day, because of hypoK on labs, he received IV KCl replacement almost concurrent with scheduled enteral KCl… probably would not have been a big deal, except for propranolol impairing ability to transport extracellular K intracellular [3/]

#EPeeps #FellowsFirst The cardiac ICU calls that they are preparing to cardiovert this wide-complex tachycardia. Do you agree? What may be going on?

#EPeeps Many suggested sodium channel blockade or hyperkalemia

This was BOTH! Severe transient hyperkalemia superimposed on high-dose flecainide

Very complex infant on multiple AADs including high-dose propranolol for intractable EAT

Do you know why the propranolol matters? 👇

See separate thread on hyperkalemia and beta blockers for the conclusion

🧵 on the Algorithmic Localisation of Accessory Pathways from ECG

A concept I’m getting to grips with made easier by a beautiful review by #Crinion & @adribaran in Card Electrophysiol Clinic (PMID 33161996)

#EPeeps #MedEd #Cardiology

🫀Considerations of AP localising algorithms:

A. Only apply to manifest antegrade AP & not concealed AP which conduct retrograde

B. Algorithms focused on atrioventricular AP & not other rarer AP

C. Depend on the degree of preexcitation with

D. Cautions with multiple APs

🩻 Anatomic Nomenclature

- AP locations is described in the LAO view
- Older algorithms use anatomical descriptions derived from the Valentine heart position & not attitudinally correct nomenclature which can be confusing

September is #AFibAwarenessMonth!
A🧵on the basics of #AFib

#ACCEP #EPeeps #CardioTwitter

#AFib is the most common sustained heart rhythm problem in the world. 🌎

#AFib increases the risk of #stroke & #heartfailure. It causes symptoms like fatigue, dizziness & shortness of breath and can reduce patients’ quality of life.

#ESCCongress

Let's get straight to the point about #INVICTUS

The only people not surprised by the results are imagers that do TOEs (TEEs) on these patients! No way VKA was going to lose to NOACs here!😂

A 🧵...

#medtwitter #cardiotwitter #echofirst #epeeps

#ESCCongress
Patients with rheumatic MV disease typically have very different atrial appearances on TOE. No matter how well anticoagulated, there is very often spontaneous echo contrast in the LA

These atria are just different...why?

Who is this?

The answer is Ludwig Aschoff (1866 - 1942), German physician & pathologist

He described what are now known as Aschoff bodies - inflammatory infiltrates in the atrial walls that eventually turn to fibrotic tissue, which contributes to the atrial myopathy we see in these patients

🧵 1/7 Ever wondered why the Osborn wave looks the way it does? Stay with me during my newest #tweetorial. A thread 🧵1/7
#cardiotwitter #EPeeps #CardioEd #MedTwitter @TRassafMD @YoungDgk @DGK_org @YoungDZHK @AaronGoodman33 @Steph_Achenbach @fuzzymittens @AvrahamCooperMD

2/7 History
First described in 1953 by Osborn (camel-hump sign) upon #hypothermia in dogs. Upon systemic analysis similar #ECG patterns have been described in
➡️ hypercalcemia
➡️ brain injury
➡️ SAB
➡️ vasospastic angina / ischemia

3/7 Emslie-Smith et al showed that Osborn waves manifested more in epicardial than endocardial leads. Others finally showed that 4-aminopyridine sensitive transient outward current (Ito) is responsible and predominantly located in epicardium. ⬇️ heart rate led to ⬆️ Ito current

🧵What does the left atrial appendage do? Is it just a nidus for thrombus?

A brief review of proposed & proven functions of the LAA👇

#CardioTwitter #EPeeps #MedEd
@drpaulfriedman @ChetRihal

#1 LAA plays a very important capacitance role.

Animal studies in 1990s showed:

- LAA is more compliant than LA
- LAA acts like a decompression chamber during systole
- The capacitance/reservoir role is key when LAP is elevated
- Eliminating LAA acutely ⬆️ LA pressure in dogs

- Effect of LAAO on hemodynamics in humans is debatable

- OBS data ➡️ that LAAO ⬆️ LAP, ⬇️ LA transport function, ⬆️ HF

- However, in LAAOS III RCT there was no ⬆️ in HF admissions w LAAO

- Caveat: epicardial closure vs ednocadail plugging of LAA don’t produce similar effects

@syamkumarmd

Another interesting "Bigemini" pattern 😀. #EPeeps #Cardiologytrainees. Try explaining the mechanism and diagnosis? @EPeeps_Bot

Is this true bigemini or "pseudo bigemini"? Reason?

The purpose of this post was to highlight a "measurement error". When we measure the RR intervals in wide complexes, always do from the beginnings of the R waves, not the peak. here delay in the later part of the QRS is causing an illusion of a later QRS, but RR is constant.

1/ A tweetorial- Watchman Left Atrial Appendage Occlusion!

#LAAO #Watchman #StructuralHeartDisease #EPeeps #interventionalcardiology @EPeeps_Bot @RadialFirstBot @EchofirstB @BotPci @TAVRBot

2/ what is the left atrial appendage?

The LAA is derived from the left wall of the primary atrium (embryo). Its diff from the true LA and its suited to function as a decompression chamber during left ventricular systole and during other periods when left atrial pressure is high

3/ the appendage is like your fingerprint. No two are the same.

Common shapes are:

🥦Cauliflower/Broccoli (hardest)
💨Windsock (easiest)
🐓Chicken wing
🌵Cactus
