Cardiac myxoma is the most common cardiac tumor in patients of all ages; the majority are encountered as single left atrial tumors. Left ventricular myxomas are exceedingly rare, having been recorded in a small number of case reports involving children worldwide. We report a case of a left ventricular myxoma with left ventricular outflow tract obstruction in a previously healthy, asymptomatic adolescent black male. Transthoracic echocardiograms revealed a single, large (2.5 × 5-cm), lobulated, mobile mass within the left ventricular cavity that oscillated into the outflow tract, thereby causing moderate obstruction during systole. Advanced images delineated the location and tissue composition of the mass, characterizing it as a myxoma. Complete surgical excision of the mass was accomplished via aortotomy. Gross examination and histology confirmed the diagnosis of myxoma.
