Cardiac rhabdomyoma and tuberous sclerosis: prenatal diagnosis and follow-up.

This article reports 4 cases with cardiac rhabdomyomas diagnosed during intrauterine life. Echocardiographic follow-up at 9-30 months showed regression of the tumors in 3 cases (75%). Two cases (50%) developed tuberous sclerosis during that period. Fetal echocardiography promotes early diagnosis of tuberous sclerosis through prenatal detection of cardiac rhabdomyoma, and facilitates genetic counselling of families at risk.
