Evaluation of the Role of Endomyocardial Biopsy in 851 Patients With Unexplained Heart Failure From 2000–2009

Abstract

We confirm that EMB is useful in acute onset unexplained cardiomyopathy. We demonstrate a role for EMB in suspected infiltrative disease and in the management of rare clinical scenarios, such as suspected hypersensitivity myocarditis, anthracycline cardiomyopathy, cardiac tumors, and arrhythmogenic right ventricular dysplasia/cardiomyopathy. Our results suggest low use of EMB in chronic heart failure that responds to usual care.
