目的：探讨经食管超声心动图（TEE）与心肌超声造影（MCE）在心脏黏液瘤中的临床价值。方法：总结29例心脏黏液瘤的常规经胸超声心动图（TTE）、MCE及TEE特征，并与病理结果对比。结果：TTE对黏液瘤形态、回声及瘤蒂的诊断率分别为93.1%（27/29）、93.1%（27/29）、51.7%（15/29），均低于TEE（均为100%），TTE与TEE对瘤蒂的诊断率比较，差异有统计学意义（P＜0.05）；MCE显示29例黏液瘤均呈低增强，9例边缘增强光整，另20例边缘增强不光整；10例呈均匀增强，另19例呈不均匀增强，与手术及病理结果肿瘤的形态、内部病理改变一致。结论：TEE联合MCE能在术前评估心脏黏液瘤瘤蒂、位置、肿瘤对房室瓣的影响、血流灌注情况、形态及内部回声等，为术者提供可靠的术前信息。
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.
