The familial variant of cardiac myxomas is an autosomally dominant disease. Here, we report a case of recurrent multiple cardiac myxomas wherein the patient, a 36-year-old woman who was referred for palpitations and nocturnal dyspnea, had a relevant familial history. Her mother had undergone extirpation of cardiac myxoma when she was about 50 years old. Echocardiography showed the presence of multiple cardiac myxomas. One of the cardiac myxomas nearly obstructed the left ventricular inflow; therefore, we extirpated the myxomas under cardiopulmonary bypass and cardioplegic arrest. The operation was uneventful and the postoperative clinical course was good. Pathological examination confirmed that the extirpated mass was a myxoma. Approximately 3 years after the first cardiac operation, we found a recurrent cardiac myxoma in the same patient. She then underwent a second operation and was discharged without any complications. Pathological examination also confirmed that the cardiac mass was a myxoma and that there was no malignancy. <Learning objective: This familial multiple cardiac case is a rare case because of its multiplicity, location (especially, the myxoma in right atrium is rare) and recurrence at the same position. And we may suggest the pitfall or prevention for recurrence of cardiac myxoma.>.
