Frequency of Late Gadolinium Enhancement-Negative Cardiac Magnetic Resonance Imaging at Initial Presentation with Metabolically Active Treatment-Naïve Cardiac Sarcoidosis

Important data, but genetic testing yield in isolated cardiac FDG uptake was 12%. A negative panel (~88% of cases) neither excludes genetic cardiomyopathy nor confirms cardiac sarcoidosis. Genetic testing is a poor diagnostic test.

They even extended our findings.
CMR phenotyping had much greater interobserver reproducibility than LGE quantification.
CMR phenotyping was 5-fold faster than LGE quantification.
FDG-PET added no incremental predictive value beyond CMR phenotyping.

In a prospective cohort of 206 patients (CHASM-CS), they found that ALL ventricular arrhythmia events occurred exclusively in patients with the high-risk (pathology-frequent) LGE phenotype.
There were NO events in the low-risk patients.

In science, successful replication is the ultimate quality check!
This is a highlight for our research group—David Birnie's group (one of the biggest names in cardiac sarcoidosis) just independently replicated our CMR phenotyping work!

📄 LGE phenotype vs burden in cardiac sarcoidosis: does pattern matter more than quantity?
🔗 DOI: doi.org/10.1093/ehjimp/qyag0…
🫀 In cardiac sarcoidosis, risk stratification for ventricular arrhythmias remains challenging.
This prospective study compares LGE burden vs LGE phenotype on CMR for predicting arrhythmic events.
✨ Key findings:
🔹 The “pathology-frequent” LGE phenotype strongly predicts ventricular arrhythmias
➡️ All arrhythmic events occurred only in this phenotype
🔹 Both approaches perform well:
LGE burden (quantitative %)
LGE phenotype (pattern-based)
👉 BUT:
🔹 LGE phenotype achieved 100% negative predictive value
➡️ No events in patients without this phenotype
⚡ Practical advantages of LGE phenotyping:
✅ Much higher reproducibility (κ = 0.97 vs 0.41)
✅ ~5x faster than LGE quantification
✅ Easier to apply in clinical routine
📊 Additional insights:
👉 Arrhythmic risk is mainly linked to scar-related re-entry, not inflammation
👉 FDG-PET did not add independent prognostic value
💡 Clinical take-home message:
👉 Pattern recognition may be as important as quantification
👉 LGE phenotype could:
improve risk stratification
guide ICD decision-making
simplify clinical workflows
🚨 Bottom line:
In cardiac sarcoidosis, how scar looks may matter more than how much scar there is.

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