What conditions does a myocardial biopsy detect?

Myocardial biopsies: Myocardial biopsies can be used to diagnose a number of things microscopically, including transplant rejection (in patients with heart transplant), inflammation (myocarditis), drug toxicity, and causes of hypertrophic or restrictive cardiomyopathy (for example, amyloid,hemochromatosis, sarcoid or other more rare conditions). Neoplasms (benign or cancer) can also be diagnosed.
