We experienced a case of a recurrent left atrial myxoma in a pregnant woman with twin fetuses. Normal healthy twins weighing 1430 and 1190 gm were delivered by cesarean section performed under epidural anesthesia at 32 weeks gestation. Neither cardiac failure nor embolisms were observed during pregnancy or delivery. The left atrial myxoma was removed surgically one week after delivery. The infants and mother remain in good health. According to previous reports and our present observations, the decision for cardiac surgery during pregnancy should be based on the maternal and fetal status.
