Thanks for the shoutout! A minor clarification - the high risk phenotype does not even incorporate an abnormal LVEF!!!!

Important multicenter study in #EHJ
#CMR outperforms societal recs for ICD placement in cardiac sarcoidosis
📈AUC=0.86 for 5-yr risk of fatal/life-threatening arrhythmias
⚡Highest risk = abnl LVEF + LGE that is multifocal, septal, subepicardial, or involves RV freewall

Have you ever wondered whether your patient with CAD and cardiomyopathy truly has ischemic cardiomyopathy, or whether the CAD is a “bystander”?

You might be interested in our paper now out in Circulation

In my opinion, both trials are fundamentally useless.

What is ischemic cardiomyopathy?

Both trials defined ischemic cardiomyopathy as LV dysfunction + obstructive CAD.

This does not identify the etiology of cardiomyopathy as ischemic, but identifies the presence of CAD. Two different things!!!

I don't exactly know. But...

1 - There was no real change in ECV in Explorer HCM (PMID 33190524).
2 - An increase in ECV is not necessarily bad. It increases after AVR (PMID 29471937).
3 - The amount of dead myocardium will never decrease. So, a "decrease in LGE" does not mean less badness.

Chetan Shenoy @cshenoy.bsky.social · Jul 13

Interesting. The ECV increased 1.1% (25 min) to 2.2% (5 min), which is difficult to explain. But it explains why LGE was less; it was quantified as the amount of myocardium 6SD brighter than "remote". LGE amount will be less if the remote myocardium is brighter after mavacamten than at baseline.

“CMR phenotyping can be used immediately in clinical practice to identify patients with suspected cardiac sarcoidosis who would benefit from a primary prevention ICD," said Chetan Shenoy, MD.

In patients with suspected cardiac sarcoidosis, CMR phenotyping showed greater discriminative accuracy than societal recommendations for predicting fatal or life-threatening ventricular arrhythmias, suggesting that it may be more effective at identifying candidates for primary prevention ICDs.

Cardiac sarcoidosis is a undervalued disease and difficult to diagnose and treat, considering potential life-threatening arrhythmias. Nice to have some more guidance.

VT and VF/cardiac arrest - correct. That would be secondary prevention.

AV block is a Class IIa indication for an ICD in the guidelines for cardiac sarcoidosis. But who has cardiac sarcoidosis is not always clear.

What if patient has extracardiac sarcoidosis and complete AV block but no LGE? 🤔

In patients with suspected cardiac sarcoidosis, cardiac FDG-PET is recommended after a normal CMR if there is a high clinical suspicion. What are the data supporting this recommendation? #CardioSky #MedSky #Sarcoidosis

Query sarcoid, normal #WhyCMR, so then should we do FDG-PET? Not much benefit.

A new study in EHJ - Cardiovascular Imaging describes 324 patients with normal CMR and no high-risk features who all also had FDG-PET.

21.3% had FDG uptake.

Their annualized event rate was <1%, indicating that FDG-PET has little diagnostic or prognostic utility.
