Cardiac rhabdomyoma in the neonate: surgical management.

Rhabdomyoma is the most common cardiac neoplasm in neonates. Tuberous sclerosis is found in half of the patients with rhabdomyomas. We maintain a surgical policy of accepting for operation only neonates in whom it has been demonstrated that the primary cause for hemodynamic compromise is obstructing, intracavitary neoplasms. Only the intracavitary portions of the rhabdomyoma are excised; no effort is made to completely remove all intramural tumors. Rhabdomyomas demonstrate benign pathological characteristics and may regress. Neonates with rhabdomyomas but no hemodynamic impairment, or those in whom only intramural masses can be demonstrated, are not considered surgical candidates. Tuberous sclerosis by itself should not be judged a contraindication to operation. The results of our surgical policy regarding rhabdomyomas in neonates are reported in two case presentations.
