I had the privilege to help to launch the much waited new low profile sheath for impella. These are the main changes: 1. No need to peel away, not tapered and leave in!! 2. 1.5 fr smaller than prior generation 3. Hydrophilic dilator, no need to pre dilate (was already not doing but even easier now) 4. Coiled making it kink resistant 5. Side port is short and with bigger caliber. That might open the possibility for external bypass using the leave in sheath! 6. Easier single access 7. New improved reposition/locking mechanism (similar to the 5.5) For me the best is getting rid of the reposition sheath! That will make our Cardiogenic shock care in the ICU much better!! @UICcardfellows @Babar_Basir @evandrofilhobr

Introducing the percutaneous aorto-coronary bypass graft. The VECTOR procedure revascularizes the left main coronary artery using retrograde and antegrade steps: a retrograde wire exits the left main (distal graft), an electrosurgical wire exits the aortic root (proximal graft), a guidewire rail is created, and a stent graft is delivered from the aorta to the left main. What could possibly go wrong? ahajournals.org/doi/10.1161/CI…

🧵 Starling’s Law: Misunderstood, Misapplied, and Still Misleading 1 🚨 “Starling’s Law explains how the heart increases cardiac output.” You’ve probably heard this a thousand times. But it’s wrong. Or at least - very incomplete. Let’s fix it. Because this matters - for heart failure, fluids, vasopressors, inotropes, afterload, and how we think about the whole system.

@tedcruz @grok is Ted Cruz a puppet of AIPAC?

ON OCTOBER 8, he couldn’t bring himself to condemn Hamas, the murder of 1200 Jews, or the rape of women & little girls. Instead, he just…blamed Israel. On October 8.

@ZohranKMamdani @BillAckman how sad for you LOL. Congratulations @ZohranKMamdani

In the words of Nelson Mandela: it always seems impossible until it’s done. My friends, it is done. And you are the ones who did it. I am honored to be your Democratic nominee for the Mayor of New York City.

Early morning wake up - guess the culprit with @jedicath ! How would you manage this? Will share what I did.. #cardiotwitter

A patient with known cardiomyopathy in ICU, had viral prodrome. BP 81/45 mmHg. Sinus rhythm with narrow QRS. Properly aligned CW interrogation across the mitral valve is shown, what are the findings and hemodynamic implications?

MANTA is an effective large-bore VCD in TAVR. Downside: lack of convenient bailout. Conventional bailout (contralateral CFA or radial) may not be fast (major bleeding) or easy (vessel dissection/total closure) enough. What to do? 🧵 1/ @TCT_ME_ #TCTMiddleEast @crfheart @MyJSCAI

How I Talk About Left Main PCIs - And You Should Too!* 🧵 (*A suggestion of course!) This is one of the cases from my talk on MCS for high risk PCI. Case first, then the analysis. 86 year old man, unstable angina, EF 40%, turned down for CABG at OSH, transferred with IABP. The

No IC wants this- but, every one who works in cath lab need to know how to handle this menace ! Mid LAD perforated following pre dilation with 2.5 🎈 at 10 🏧 . Hwo would u handle this #cardiotwitter #CardioX

Excited to join the amazing team at Deborah Heart next year for my interventional cardiology fellowship. Alhamdulillah.

🧵1/Caumel's Law Explained! Caumel's law explains why we see alternating WCT and NCT with accessory pathways (ORT)! - If no BBB, ORT will look narrow. TCL will be shorter. - If "ipsilateral BBB" developed, ORT will look wide and TCL is longer. #EPeeps

We discussed this observation on #CardioTwitter: several noted that administering a heparin bolus the ER (100 units/Kg, not max 4,000), rather than waiting until the cath lab, improves TIMI flow by the time the patient reaches the cath lab. This is now supported by an RCT! #TCT2024 @crfheart

Transcatheter Aortic-Valve Replacement for Asymptomatic Severe Aortic Stenosis: @NEJM 🥸 I was at #TCT2024 all day - just got to a desk @TCTMD 😱 Summary of EARLY TAVR trial 👇👇👇

The most shocking trial in modern cardiology continues to find no signal of PCI benefit, despite enrolling pts most likely to benefit. How the “clogged pipe” frame of thinking persists despite such evidence amazes me.

78 yr male with effort angina, TMT strongly +ve in stage 2 Bruce, good LV. “All right” after angio!! Today’s first case in cath lab😳😭
