Multiparametric Echocardiography and Cardiac Biomarkers in Pediatric Inflammatory Heart Diseases

Multiparametric Echocardiography and Cardiac Biomarkers in Pediatric Inflammatory Heart Diseases (Including Pediatric Inflammatory Multisystemic Syndromes Related to Covid 19, Kawasaki Disease and Myocarditis)

Acquired inflammatory or infectious cardiac diseases, in pediatrics, include Kawasaki disease, myocarditis, and Covid-19-related Pediatric Multisystemic Inflammatory Syndrome (PIMS).

These 3 inflammatory cardiac diseases have clinical, biological, and echographic similarities and differences. Nevertheless their modalities of monitoring, management and evolution are different. The investigators wish to retrospectively analyze biological and echocardiographic data of Kawasaki disease, myocarditis, PIMS patients managed at Nancy Children Hospital from January 1, 2017 to June 31, 2023.

The primary objective of this study is to identify, for these 3 pathologies, the prognostic factors of initiation of inotropic support.

The secondary objective is to identify the prognostic factors of degradation of ventricular function.

Inclusion Criteria:

• diagnostic of PIMS, myocarditis or kawasaki disease patients
• age < 18 years

Exclusion Criteria:

• uncertain diagnosis
• other complex heart disease
• management out of Nancy University children hospital center
