Ancillary tests may help in the diagnosis. Echocardiography typically gives non-specific and only occasional findings of endocardium thickening, left ventricular hypertrophy, left ventricle dilation, and involvement of the mitral and/or tricuspid valves. Gadolinium-based cardiac magnetic resonance imaging is the most useful non-invasive procedure for diagnosing eosinophilic myocarditis.
