Hypertrophic cardiomyopathy in infancy and childhood.
Hypertrophic cardiomyopathy (HCM) presented in 10 children under 2 years of age (group 1) and in 5 between 3 and 8 years (group 2). The clinical, ECG, chest radiographic and echocardiographic features are reviewed and prognosis over a mean follow-up period of 3.5 years is reported. Patients in group 1 had more symptoms and 7 had evidence of heart failure at some stage; all had ECG abnormalities. Group 2 patients presented with murmurs and only 1 had heart failure. Medical management of these patients is discussed and the importance of accurate diagnosis stressed, since HCM may have a poor prognosis in childhood; 3 out of 15 patients have died.
