Cardiac Myxoma : Treatment
Treatment of Cardiac Myxomas: Excision is curative. Tumors with a well-defined narrow stalk are simply resected without removing atrial septal tissue. Broad-based tumors often show lepidic cells extending along the adjacent endocardium. Such cases are treated with a wide local excision along with a portion of atrial septum and fossa ovalis at the site of attachment (as seen here). The resultant gap is closed with a synthetic or pericardial patch. With modern surgical techniques, recurrence rate is <2% for sporadic tumors and about 20% for familial myxomas. Recurrences in familial cases can be at intracardiac sites different from the original resection and are likely to be multiple primary tumors rather than true recurrence of the original tumor.
