目的：探讨二维经食管超声心动图（2D TEE）及实时三维经食管超声心动图（RT3D TEE）对心脏占位性病变的诊断价值。方法：对比研究26例心脏占位性病变的二维经胸超声心动图（2D TTE）、2D TEE及RT3D TEE，并与手术结果做对比。结果：2D TEE对心脏占位诊断率（76.9%）明显高于2D TTE诊断率（30.8%），2D TEE诊断心脏良、恶性肿瘤的敏感性（100%）及特异性（100%）高于2D TTE诊断敏感性（86.9%）、特异性（60.0%），2D TTE、2D TEE及RT3D TEE所测占位大小与手术标本大小比较，差异均无统计学意义。而相关性比较，2D TEE相关性最好。结论：2D TEE较2D TTE能更清晰显示心脏占位的大小、形态、位置、毗邻关系等，在鉴别心脏肿瘤性质及辅助选择手术方式方面有更好的应用价值。
Abstract
Objective: To study the diagnostic value of two dimensional transesophageal echocardiography(2D TEE) and real-time three dimensional transesophageal echocardiography(RT3D TEE) for cardiac mass. Methods: Twenty-six subjects were examined by two dimensional transethoracic echocardiography(2D TTE), 2D TEE and RT3D TEE. The anatomical characteristics and adjacent structures of mass were compared with operation. Results: Compared with 2D TTE, 2D TEE can diagnose the cardiac mass and differentiate the cardiac tumor more accurately. Conclusion: 2D TEE has higher application value than 2D TTE in differentiating cardiac masses and in the choice of operation.
