Monitoring
Recommended follow-up is dictated by the clinical course of the individual patient. Patients who exhibit only mild symptoms with prompt resolution of symptoms should be followed closely initially, but monitoring can be quickly spaced out to annual visits unless symptoms recur. However, patient with persistent left ventricular (LV) dysfunction or evidence of progression of myocardial inflammation warrant regular follow-up at least every few months or sooner until the patient is stable clinically.[55][75]
In children, biopsy or cardiac MRI may be necessary if ventricular function, inflammatory biomarkers, or viral activity continue to be abnormal at follow-up.[15]
