Spontaneous Regression of Cardiac Rhabdomyoma in Tuberous Sclerosis

Life-threatening cardiac rhabdomyoma in a newborn infant regressed spontaneously within a 5 month period. Since cardiac surgery for rhabdomyoma is dangerous in infancy, medical management should be considered if symptomatology is not severe. When a fetal arrhythmia is diagnosed, antenatal ultrasound examination for presence of cardiac tumors is warranted.
