Endomyocardial Biopsy in the Diagnosis of Cardiac Sarcoidosis

Eur J Heart FailPublished

  • Retrospective cohort study

Authors' conclusion

The sensitivity of EMB in CS depends on the extent, activity, and location of myocardial involvement, being the higher the more severe CS is.

Study context

Population
Consecutive patients with cardiac sarcoidosis meeting Heart Rhythm Society diagnostic criteria (mean age 49 years, 60% female)216 (83%) underwent endomyocardial biopsy (EMB)
Participants
260 patients
Outcome
Diagnostic sensitivity of endomyocardial biopsy (EMB) in cardiac sarcoidosis

Main finding

As reported in the abstract

EMB sensitivity

EMB overall sensitivity

38%

EMB sensitivity after repeat biopsies

49%

Observational data: associations, not effects.
