Adjunctive studies
(1) Polymerase chain reaction (viral genomes—myocarditis)
(2) Transmission electron microscopy (myocarditis/cardiomyopathy/amyloidosis)
(3) Immunohistochemistry (acute allograft rejection/amyloidosis/neoplasm/cardiomyopathy)
(4) Histochemical stains (storage disease/metabolic disease)
(5) Immunofluorescence (rejection/cardiomyopathy)
