One-stage complete removal of intracardiac leiomyomatosis without cardiac arrest.

We present here a woman with an intracardiac leiomyoma originating from uterine leiomyomatosis. The tumor was completely removed in a one-stage procedure using cardiopulmonary bypass without cardiac arrest. Most one-stage operations were performed with total circulation arrest; however, using of on-pump beating-heart technique when removing the intracardiac mass has seldom been reported in detail. The patient was asymptomatic with no evidence of recurrence on 13-month follow-up.
