Abstract Objective: To evaluate the clinic value of transesophageal echocardiography(TEE) and myocardial contrast echocardiography(MCE) in the diagnosis of cardiac myxoma. Methods: Imaging features of transthoracic echocardiography(TTE), TEE and MCE in 29 patients with cardiac myxoma were summarized and compared with histological results. Results: The diagnostic rate of tumor pedicle by TTE was significantly lower than by TEE(P＜0.05). Twenty-nine cases showed low enhancement. Nine cases showed smooth boundary and 20 cases showed unsmooth boundary. Ten cases were homogeneously enhanced while the other 19 cases were inhomogeneously enhanced. The MCE of cardiac myxoma was consistent with histological results. Conclusion: TEE and MCE can evaluate the pedicle, location, affect on atrioventricular valve, blood perfusion, shape and echo of myxomas. It can provide dependable information for operator.
