Pediatric carduiomyopathies [CMPs] are complex and present challenges to both cardiologists and pediatricians. The incidence of pediatric CMPs is significantly higher in the first year of life than in older age. All types of CMP may be present in early childhood. The most frequent type is dilated cardiomyopathy [DCM], while familial hypetrophic cardiomyopathy [HCM] caused by contractile protein abnormalities usually develops, at least in some series, after the first decade of life.
