Primary malignant tumors of the heart - surgical treatment and experience of the Department of Cardiac Surgery `Sveta Marina` University Hospital Varna

Abstract

Primary cardiac tumors are rare with an incidence of 0.0017 to 0.0019%. Approximately 25% of these tumors are malignant, represented primarily by sarcomas. Most common types of sarcoma are leyomiosarcoma and angiosarcoma. Other histhologic subtypes of sarcoma are considerably less common. Since 2008 we have diagnosed and treated two cases of malignant heart tumors in our intitution. Both tumors were of extremely rare morphologic subtype - liposarcoma and malignant histiocytoma. To our knowledge there are 18 cases of primary liposarcoma of the left ventricle and 20 cases of malignant histiocytoma described in specialized literature up to current date.We present both our cases of primary malignant heart tumors with diagnostic, surgical and postoperative details including long term follow-up.Key words: liposarcoma, histiocytoma, malignant, surgical treatment
