2/ Middle age patient with hx of CAD and PCI to LAD presents with significant SOB and elevated Hs-Trop. No chest pain. No ECG changes. Echo with inferior hypokinesis.
Here’s the diagnostic with a JR4.
Notice the filling defect in the RCA. This is thrombus. How do we know?

3/ Keys of #thrombus on angiogram
🔑 contrast staining
🔑 Lack of calcium on non con image
🔑 ovoid filling defect (complete lumen)

How would you tackle this heavily calcified LAD with calcified #nodule that was appropriately identified by intravascular imaging? #OCT
doi.org/10.1093/ehjcr/…
In this #EHJCaseReports #tweetorial we take a deep dive into the Rx of #calcified coronary lesions.

Calcified lesions are top of the totem pole of complex PCI
Main armamentaria are balloon-based #IVL & ablation-based (rotational/orbital) techniques, while ancillary tools eg guide extension catheters are useful too. eurointervention.pcronline.com/article/intrav…

I recently saw a controversial tweet arguing against tx of chronic clot and restricting tx SOLEY to the CFV/iliac. While I agree (for the most part)- data is limited. At the end of the day we care about the pt, and not every pt is the same! Case➡️

Honeycomb-like structure, a rare cause of myocardial ischaemia has multiple communicating channels divided by thin septa. Angiographically fuzzy & hazy appearance often without significant stenosis, they're best detected on high-resolution IVUS/OCT

MINOCA has MI in it-> DOES the definition allows for the inclusion of non-ischemic causes of troponin elevation?
Given this limitation of the troponin bioassay, the “Fourth 4th Universal of MI" defined Injury from infarction
INJURY IS NECROSIS WITHOUT ISCHEMIA!

The hallmark of myocardial injury ⬆️ troponin, However, these entities differ conceptually
▶️ myocardial injury = nonischemic mechanisms of myocyte injury (eg, myocarditis),
▶️MI = ischemic mechanisms (eg,
plaque disruption or supply-demand mismatch).

Wall shear stress (#WSS) is the frictional force of blood exerted tangential to endothelial surface of vessel wall & expressed in variety of units (1Pa=1N/m2=10 dynes/cm2)
It is derived from
• luminal geometry
• flow rate
• blood viscosity
• near wall velocity values

In vivo WSS calculations are derived from computational fluid dynamic (#CFD) simulations created from reconstructed 3D vessel geometries (from biplane angio/IVUS/OCT/CT/MR) combined with patient-specific pulsatile inlet/outlet velocity values (Doppler wire or other methods)
