The use of 3D technology has significantly improved the diagnostic accuracy of echocardiography by overcoming the limitation of 2D echocardiography. Transillumination 3D image post processing technique enhances shadows and contrast of cardiac structures with a movable virtual light source improving further the clarity and detail provided by conventional 3D imaging. In this report, we present 3 cases, one of mobile atherosclerotic aortic root plaque, another of small thrombi on ICD lead, and a third case of bicuspid aortic valve perforation due to infective endocarditis in whom TEE 3D transillumination further improved the diagnostic quality of conventional 3D imaging and lead to accurate clinical diagnosis.
3D 技术的应用通过克服 2D 超声心动图的局限性，显著提高了超声心动图的诊断准确性。透照 3D 图像后处理技术通过使用可移动的虚拟光源增强了心脏结构的阴影和对比度，进一步提高了常规 3D 成像提供的清晰度和细节。在本报告中，我们介绍了 3 个病例，其中一个是移动性动脉粥样硬化主动脉根部斑块，另一个是 ICD 导丝上的小血栓，第三个是感染性心内膜炎导致的二叶式主动脉瓣穿孔，TEE 3D 透照进一步提高了常规 3D 成像的诊断质量，并导致了准确的临床诊断。
