经食道多普勒超声心动图(TEE)是近年来超声成像技术“腔隙化”发展而获得高质量显像的高新技术之一。常规地经胸超声心动图(TTE)虽能成功的显示大多数心血管疾病的形态学和血动学影像,但约有20％的患者因透声窗条件(肥胖、肺气肿等)和近场范围的限制而难以获得满意的图像。TEE能有效地克服透声
Transesophageal Doppler echocardiography (TEE) is one of the high-tech technologies that has achieved high-quality imaging in the “lacunar” development of ultrasound imaging in recent years. Conventional transthoracic echocardiography (TTE) can successfully display the morphological and hemodynamic images of most cardiovascular diseases, but about 20% of patients suffer from translucent window conditions (obesity, emphysema, etc.) and Near-field limits make it difficult to obtain satisfactory images. TEE can effectively overcome the sound transmission
