Abstract

This article summarizes and analyzes the clinical features and gene mutation characteristics of children with noncompaction of the ventricular myocardium (NVM). For the 6 children with NVM (4 boys and 2 girls), the age of onset ranged from 3 months to 12 years. Of the 6 children, 5 had arrhythmia, 3 had cardiac insufficiency, 1 had poor mental state, and 1 had chest distress and sighing. NVM-related gene mutations were detected in 4 children, among whom 2 had MYH7 gene mutation, 1 had PRDM16 gene mutation, and 1 had mutations in the ACTN2 and TNNT2 genes. Four children had improvement in cardiac function. The two children with no significant improvement in cardiac function had a younger age of onset, a greater reduction in systolic function on echocardiography, and greater increases in myocardial enzyme and N-terminal pro-brain natriuretic peptide. It is concluded that for children with the initial symptoms of chest distress, sighing, arrhythmia, enlarged heart shadow, and increased myocardial enzyme, echocardiography and cardiac magnetic resonance are recommended for the diagnosis of NVM. NVM can have various genetic mutations.
