Cardiovascular Imaging in Pediatric Myocarditis

A Cohort Study: to Assess the Value of Cardiovascular Imaging in Pediatric Myocarditis

This study aims to utilize cardiac magnetic resonance (CMR) to assist in the clinical diagnosis, conduct consecutive assessments for myocardial tissue in pediatrics with myocarditis, and explore effective predictive factors for adverse outcomes in pediatric myocarditis.

Participants will undergo baseline collection, laboratory tests, echocardiography, and CMR. All the consecutive data will be used to analyze the association with the diagnosis and prognosis of pediatric myocarditis.

Inclusion Criteria:

• Patients diagnosed or suspected pediatric myocarditis based on Diagnostic Recommendation for Myocarditis in Children (version 2018).
• Age between 1 to 18 years old.

Exclusion Criteria:

• Previous history of cardiovascular disease ( e.g. congenital heart disease, cardiomyopathy, rheumatic heart disease, valvular disease ).
• MRI examination contraindications ;
• Gadolinium contrast agent contraindications ;
• CT examination contraindications ;
• Comparison of iodine content.
