Abstract：Objective To investigate the value of echocardiography in the preoperative diagnosis of primary right ventricular tumors.Methods The clinical manifestations and echocardiographic features of 30 patients with primary right ventricular tumors diagnosed by surgical pathology in Beijing Anzhen Hospital,Capital Medical University from April 2016 to January 2024 were retrospectively analyzed.With the pathological results as the gold standard,the coincidence rate of echocardiography in the pathological diagnosis of primary right ventricular tumors was analyzed.Results Among 30 patients with primary right ventricular tumors,postoperative pathological results showed that 24 cases(80.0％)were benign tumors and 6 cases(20.0％)were malignant tumors.Benign tumors included 11 cases of myxoma,6 cases of fibroma,4 cases of rhabdomyoma,1 case of mature teratoma,1 case of papillary elastofibroma and 1 case of lipoleiomyoma.Malignant tumors included undifferentiated pleomorphic sarcoma,angiosarcoma,synovial sarcoma,myxofibrosarcoma,leiomyosarcoma,and malignant hemangioendothelioma in 1 case each.The coincidence rate between preoperative ultrasound diagnosis and postoperative pathological diagnosis was 36.7％(11/30).The ultrasound features of myxoma were highly specific,and the coincidence rate of ultrasound diagnosis was 9/11.The characteristic manifestations of myxoma included:moderate echo,irregular shape,lobulated shape,pedicle attachment,loose structure,large activity,shape changes with the rhythm cycle,and the tumor was embedded into the valve orifice to varying degrees during diastole,and secondary stenosis.There were no pedicles in 6 cases of malignant tumors,while 15 cases(62.5％)of benign tumors had pedicles.There was significant difference between the two groups(P=0.017).The ultrasound echocardiographic features were compared between the benign and malignant tumor groups.In the malignant tumor group,there were 5 cases of irregular morphology,4 cases of pericardial effusion,5 cases of poor mobility,5 cases of unclear boundaries,4 cases of tricuspid regurgitation,and 2 cases of right ventricular outflow tract obstruction.In the benign tumor group,there were 6 cases(25.0％)with irregular morphology,4 cases(16.7％)with pericardial effusion,7 cases(29.2％)with poor mobility,5 cases(20.8％)with unclear boundaries,11 cases(45.8％)with tricuspid regurgitation,and 7 cases(29.2％)with right ventricular outflow tract obstruction.There were statistically significant differences in the proportion of irregular morphology,concomitant pericardial effusion,poor mobility,and unclear boundaries between the two groups(P=0.016,0.029,0.026,0.009).There was no statistically significant difference in the proportion of tricuspid regurgitation and right ventricular outflow tract obstruction(P=0.651,1.000).Conclusion Primary right ventricular tumors are mostly benign tumors.Echocardiography can find the space-occupying lesions in the cardiac cavity,provide the location,size,shape and boundary of the tumor,and also indicate whether the cardiac tumor has an impact on hemodynamics.Combined with the clinical characteristics of patients and echocardiography characteristics,preliminary pathological nature can be determined.It has a certain value in preoperative diagnosis of primary right ventricular tumors.
