Case definitions for myopericarditis or perimyocarditis¶ include: |
Suspected myopericarditis or perimyocarditis: Criteria 1 plus 2 and 3 |
Probable myopericarditis or perimyocarditis: Criteria 1, 2, 3, and 4 |
Confirmed myopericarditis or perimyocarditis: Histopathologic evidence of myocarditis by endomyocardial biopsy or on autopsyΔ |
ECG: electrocardiogram; LV: left ventricular; MRI: magnetic resonance imaging.
* Pericardial effusion confirms the clinical diagnosis, but its absence does not exclude it.
¶ The term "myopericarditis" refers to cases of confirmed acute pericarditis with elevated troponin but without LV systolic dysfunction. The term "perimyocarditis" refers to cases presenting as acute pericarditis with elevated troponin and LV ejection fraction less than 55%. The diagnostic approach and management for perimyocarditis are the same as for myocarditis.
Δ While a confirmed diagnosis would require an endomyocardial biopsy, in clinical practice this is not warranted for self-limited cases with predominant pericarditis.Do you want to add Medilib to your home screen?
