Abstract:
Rhabdomyoma is the most frequently seen primary cardiac tumor in childhood. It is usually benign. It affects the cardiac conduction system and may cause arrhythmia. In fetal and postnatal life, hemodynamic effects are rarely seen due to large masses. We present cases of rhabdomyoma associated with supraventricular tachycardia in a 23-gestational week-fetus and 2-month old infant.
