Abstract:
Objectives:To investigate the clinical value of contrast echocardiography in the detection of right heart space-occupying lesions. Methods:The imaging and clinical data of 39 patients with right heart space-occupying lesions confirmed by surgery,pathology and clinical treatment in Yanbian University Hospital from January 2019 to January 2023 were retrospectively analyzed.All patients underwent contrast echocardiography and cardiac magnetic resonance(CMR)examinations.The contrast echocardiography features of right heart neoplastic from non-neoplastic occupying lesions were summarized.The diagnostic efficacy of contrast echocardiography and CMR in right heart space-occupying lesions was compared. Results:Among the 39 patients,12 patients(30.8%)were confirmed as thrombus and vegetation,6 patients(15.4%)as benign tumors and 21 patients(53.8%)as malignant tumors.There were 8,4,4 and 17 patients of thrombus,vegetation,benign tumor and malignant tumors located in right atrium,respectively.Contrast echocardiography was used to diagnose thrombus and vegetation in 12 patients(30.8%),benign tumors in 5 patients(12.8%),malignant tumors in 22 patients(56.4%).CMR was used to diagnose thrombus and vegetation in 18 patients(46.2%),benign tumors in 5 patients(12.8%),malignant tumors in 16 patients(41.0%).The Kappa coefficient between contrast echocardiography and clinical diagnosis was 0.956(P<0.001).The Kappa coefficient between CMR and clinical diagnosis was 0.754(P<0.001). Conclusions:Contrast echocardiography can dynamically observe the degree of vascularization in the lesion tissue in real-time,accurately distinguishing the nature of the right heart space-occupying lesions.
