Multiple recurrences of nonfamilial cardiac myxomas: a report of two cases

Cardiac myxomas are the most common primary cardiac tumors. Surgical resection usually provides definitive treatment; however, postoperative tumor recurrence has been reported, especially when myxomas occur as part of a familial pattern. Only a few cases of 2nd recurrence of nonfamilial cardiac myxoma have been reported. We report 2 cases of nonfamilial cardiac myxoma, with multiple recurrences after surgical resection. The possibility of repeated recurrence of cardiac myxomas demonstrates the importance of regular echocardiography after surgical resection in order to detect such recurrence. Future studies, including genetic analysis of patients with recurrent cardiac myxomas, are warranted to investigate the nature of these tumors.
