Diagnosis and surgical treatment of cardiac tumors of the right ventricle / 中华胸心血管外科杂志

ABSTRACT

Objective To discuss the diagnosis and surgical treatment of the primary right ventricular tumors.Methods The results of surgical treatment of 7 patientss (5 males,2 females; median age,48 years,range,37 to 68 years) with primary right ventricular tumors hospitalized from Jan,1999 to May,2012 were analyzed.By preoperation echocardiography,cardiac myxoma was diagnosed in 2 cases,and cardiac space-occupying lesion was diagnosed in 5 cases.Median sternotomy were performed in all the 7 cases for biopsy or resection of tumor.when resection of tumor,extracorporeal circulation and cardiac arrest were performed.Results The 7 patients accounted for 4.96％ of patients with cardiac tumors surgically treated in the corresponding period.Complete resection of tumor was performed in 5 cases,and only biopsy in 2 cases.The pathological diagnoses included myxoma in 2 cases,lipoma in 1 case,liomyoma in 1 case,undifferentiated sarcoma in 1 case,and mesenchymal sarcoma in 2 cases.There was no in-hospital death.During a follow-up of 1 ～ 51 months (median,38 months),the 3 cases of sarcoma died,and the other patients were good and showed no recurrence.Conclusion The incidence rate of primary right ventricular malignant tumor is relatively high.Echocardiography is the most important diagnosis method.The prognosis of right ventricular malignant tumor is poor.The results of surgical treatment of right ventricular benign tumor are satisfactory.
