The main reason for performing an<unk>  is to assess allograft rejection following heart transplantation and sometimes to evaluate cardiomyopathy, some heart disease research and ventricular arrhythmias, or unexplained ventricular dysfunction. Transplant monitoring Visualising the microscopic appearance of the heart muscle allows the detection of cell-mediated or antibody-mediated rejection and is recommended episodically during the first year after heart transplantation. Occasionally, monitoring continues beyond one year. The use of<unk>  in heart transplant rejection surveillance remains the gold standard test, although the pre-test predictors of rejection cardiac magnetic resonance imaging (CMR) and gene expression profiling, are increasingly used. Myocardial diseases<unk>  has a role in the diagnosis of viral myocarditis and inflammatory myocarditis.
