ABSTRACT: This report describes two cases of juvenile hypertrophic cardiomyopathy (HCM) in which prominent bi-atrial enlargement was observed on standard 12-lead electrocardiogram, suggesting inherent predis-position to extreme enlargement and/or hypertrophy may exist in atrial myocardium in juvenile HCM. Comparative study between juvenile and adult HCM patients using a large sample size is required to confirm this hypothesis.
