Persistent strain abnormalities may linger after EF recovery in pediatric myocarditis; leaves open whether routine strain monitoring refines follow-up risk stratification.
Myocarditis is a common cause for acute heart failure in the pediatric population. Various imaging modalities have evolved over the past 3 decades in order to noninvasively image the myocardium in this patient population. These include standard 2-dimensional echocardiographic imaging, tissue Doppler imaging, and magnetic resonance imaging of the heart. More recently, myocardial speckle tracking also known as strain imaging has been utilized to assess regional wall motion abnormalities with increasing accuracy. We report a case of acute myocarditis in a teenage female in whom progression of myocardial strain findings correlated with the rapidly evolving clinical course of the patient.
