A 12-year-old girl has experienced palpitation and dizziness, and presented atrial flutter with maximal heart rate of 220/min. Two-dimensional echocardiogram and chest MRI revealed a mass attached to the inter-atrial septum. Complete excision of the tumor including the atrial septum was performed without damage to tricuspid valve. The interatrial septal defect was closed primarily. Histology of the tumor was compatible with cardiac rhabdomyoma. Sinus rhythm was present and no tachycardia occurred in the postoperative period. On the literature, only one case of isolated cardiac rhabdomyoma developing in the atrium was reported and this is considered as the oldest operative case in Japan.

Rhabdomyomas are the most common primary cardiac tumors in childhood, and are considered to be congenital lesions. They are uncommon in adolescents and adults due to their tendency for spontaneous regression. Majority of them are located in the ventricular chambers, and are also associated with tuberous sclerosis. The indications for surgery include hemodynamic compromise and intractable arrhythmias. We describe a right atrial rhabdomyoma in a previously healthy 16-year-old girl who presented with palpitation and dizziness of recent onset. Postoperative evaluation had not revealed stigmata of tuberous sclerosis.
