title: Cardiac rhabdomyoma simulating pulmonic stenosis.
abstract: The angiographic and echocardiographic findings of a right ventricular pedunculated rhabdomyoma prolapsing through the pulmonic valve which mimicked the hypoxic spells of tetralogy of Fallot are presented. A dense mass of echoes was seen within the pulmonic valve during systole. The presence of right ventricular tumor was confirmed by angiography and surgery. The abnormal echoes were no longer seen following surgical excision of the tumor.
