    Abstract:
    A rare case of right ventricular myxoma complicated by paroxysmal atrial tachycardia (PAT) is presented. A 13-year-old boy was referred to our hospital because of the recurrent episodes of PAT. Every available medical treatment was tried to reverse the PAT, during which an abnormal mass in the right ventricle was found by echocardiography. Subsequently magnetic resonance imaging computed tomography demonstrated that the tumor developed from the anterior wall of right ventricle with a pedicle. A 10 g of reddish myxomatous mass originating from the base of anterior papillary muscle was resected including the stalk during total cardiopulmonary bypass. The transient paroxysmal atrial tachycardia developed shortly after operation, however, tachycardic episode has never recurred after that. It is noteworthy that intracardiac evaluation is necessary when there is longstanding and inveterate tachyarrhythmia in otherwise healthy children.
