Authors

Pediatric hypertrophic cardiomyopathy (HCM) has a wide range of clinical manifestations. Left ventricular outflow tract obstruction (LVOTO) at rest is present in up to one-third of children with HCM, with a further 50-60% of symptomatic children developing a gradient under exertion. Treatment options are limited, and there is a relative lack of data on the pediatric population. Disopyramide is a sodium channel blocker with negative inotropic properties. This therapy effectively reduces LVOTO in adults with HCM and delays surgical interventions, but it is not licensed for use in children. We aimed to review and analyze the influence of disopyramide over the pathophysiological, clinical, electrocardiographic, and echocardiographic characteristics of patients with HCM in infancy, childhood, adolescence, and adult age. While disopyramide remains a cornerstone in the management of pediatric HCM, the advent of mavacamten and aficamten heralds a new era of potential advancements. These emerging therapies could significantly improve the quality of life and prognosis for young patients with HCM.
