In 2013, the World Heart Federation (WHF) endorsed a systematic classification referred to as MOGE(S), which combined two complementary concepts from the previous American Heart Association (AHA) and European Society of Cardiology (ESC) recommendations. The system of classification describes morphofunctional presentation (M), organ involvement (O), genetic basis (G), precise description of (genetic or acquired) etiology (E) and functional New York Heart Association (NYHA) class and American College of Cardiology (ACC)–AHA status (S). In the 2019 classification of cardiomyopathies in children, the AHA incorporated the elements of MOGE(S) in a hierarchy system based on the structural and functional phenotype with genetic and nongenetic causes as subcategories. Going forward, each new formula for reporting the classification will have to realize the need for short and rapid communication tools that can be universally adopted, but we must also recognize that the acceptance of every new proposal by the clinical community takes time. Any commitment of the clinical community has to go beyond the phenotype and include the cause as mandatory information, so that all cardiologists share a common diagnostic language.
