New in #JTCVS Open: Cold crystalloid cardioplegia appeared to be noninferior to cold blood cardioplegia for myocardial protection in elective aortic arch replacement, as suggested by comparable postoperative left ventricular ejection fraction. Read more: https://t.co/a2wq5pqy4x

MRI really helps this type of measurement

📄 Can turbulence improve how we assess aortic stenosis?
🔗 DOI: https://t.co/o9jaD399G4
🫀 Aortic stenosis (AS) grading still relies heavily on pressure gradients…
❗ But gradients are flow-dependent
❗ And can mislead us in low-flow, low-gradient AS
👉 So—are we missing something more fundamental?
✨ This study explores a novel concept:
👉 Turbulent kinetic energy (TKE) as a marker of AS severity
🧠 Why TKE?
➡️ Turbulence downstream of the valve reflects:
✔ Energy loss
✔ Haemodynamic inefficiency
✔ “Wasted work” not contributing to forward flow
👉 Potentially a flow-independent marker
🔬 Study design:
🧪 Ex-vivo model with porcine aortic valves
🔁 Different flow rates: 1 – 4 L/min
⚙️ Three stiffness grades:
SGa → normal
SGb → moderate
SGc → severe
📊 Two methods to measure TKE:
✔ Reference: particle tracking velocimetry
✔ Test: colour Doppler echocardiography
📈 Key findings:
🔥 TKE increased with:
✔ Higher flow
✔ Higher valve stiffness
👉 Both methods:
➡️ Successfully distinguished severe vs non-severe AS
📊 At high flow (4 L/min):
➡️ Severe AS showed gradients ≈ 41 mmHg
💡 The key message:
👉 TKE reflects energy loss, not just velocity
➡️ A completely different dimension of valve haemodynamics
🚀 Clinical implications:
👉 Could help in:
✔ Discordant AS cases
✔ Low-flow, low-gradient AS
✔ Situations where gradients underestimate severity
👉 And importantly:
✔ Can be estimated with standard colour Doppler
⚠️ Limitations:
❗ Ex-vivo model
❗ Needs clinical validation
🚨 Bottom line:
Turbulence (TKE) may become a new, flow-independent marker of aortic stenosis severity—potentially transforming how we assess difficult cases.

— The First Lesson as a Surgeon, Inherited from Dr. Yamamoto —
🎯 Let’s start with a question.
There’s a small circle drawn on a piece of paper in front of you.
“Put a dot inside this circle.”
How do you do it?
A: Slowly and carefully, making sure it never goes outside.
B: Quickly — just a quick flick, focusing on speed.
Which is the “right” answer?

[Manabu Takebe MD @takebe_d]

@LuisCastroMD @DrZeigler1 @JCoselli_MD @Abedeanda @tomcnguyen I don’t understand why people implante TABR in bicuspid. All data shows clear inferiority on TAVR

[Manabu Takebe MD @takebe_d]

@imghelpinghand Could you send it to me? I am curious
