Immediate surgical treatment is indicated for cardiac myxomas due to the high risk of embolization and sudden cardiac death.
Myxomas were usually detected and operated on in symptomatic patients. A high index of suspicion seems important for early diagnosis. Immunologic findings may play an additional role in confirming the diagnosis and the recurrence of a myxoma. Immediate surgical treatment was indicated because of the high risk of embolization or of sudden cardiac death. Also, a familial genesis must be excluded in myxoma patients.
Ingeborg M. Keeling (2002) studied this question.
