Urgent indications for surgery in primary or secondary cardiac neoplasm

Ten patients underwent resection of primary or secondary cardiac tumor. Two-dimensional transthoracic echocardiography per se accurately located the endoluminal cardiac mass in nine patients, and transesophageal echocardiography demonstrated a right atrial tumor in the tenth case. The indications for urgent surgery included prior embolic events (3 cases), syncopal attacks (2) or echocardiographic evidence of a multilobulated mass (2 cases). The operative strategy was standardized for atrial tumors, but for malignant myocardial neoplasm both the anatomic site and the extent of tumor growth determined the surgical procedure. Histologic examination showed myxoma in seven cases, fibroma in one and metastases of malignant melanoma in two cases. The course after resection of endoluminal benign tumor was uneventful apart from transient atrial fibrillation in four cases. Follow-up echocardiography (after 4-28 months) showed no recurrent growth. In both cases of intracardiac metastases there was recurrence within 6 to 8 months after resection of the growth.
