[Right atrial myxoma: echocardiographic diagnosis and review of the literature. Description of a clinical case].

: Two-dimensional echocardiography is the method of first choice for diagnosing right atrial myxoma. A case of right atrial myxoma, documented by two-dimensional echocardiography, is here presented. Two-dimensional echocardiography allows accurate assessment of, tumor size, site of attachment, mobility and consistency. This non-invasive technique has replaced angiocardiography in the routine preoperative evaluation of these cases. The myxomatous nature of the mass was confirmed at surgery.
