Abstract

Cardiac rhabdomyomas are rare congenital tumours resulting from an early dysembryoplastic disorder of organogenesis. They are generally benign hamartomas which may be the first manifestation of a phakomatosis, tuberous sclerosis (TS) (Bourneville disease), present in over half of cases. The cases of 11 children with cardiac rhabdomyomas are reported. All of them also had extracardiac lesions of TS. Their ages ranged from 1 day to 6 years of age. In one case, the diagnosis was made antenatally by foetal echocardiography. The clinical expression may be very serious when there are hemodynamic disturbances resulting from an obstructive syndrome (N = 3) or arrhythmias (N = 2). Nevertheless, the cardiac evolution is usually favorable (N = 9) in contrast to the neuropsychiatric outcome which is generally catastrophic (N = 8). The diagnosis is made by two-dimensional echocardiography and magnetic resonance imaging. Surgical resection of the tumours is reserved for forms complicated by cardiac failure due to intracardiac obstruction (N = 2) of life-threatening resistant arrhythmias. Genetic counseling should be directed towards prevention of TS because it is transmitted in an autosomal dominant mode. However, most of the cases are sporadic. Echocardiography should be systematic in all children with TS and is also recommended for members of their families, even those apparently unaffected, in order not to miss paucisymptomatic forms of TS.
