A transesophageal probe recently has been developed for use in pediatric patients, which incorporates 48 rather than 26 elements, and permits continuous-wave Doppler, and pulsed and color Doppler flow modalities. This probe potentially offers significantly enhanced image quality. To evaluate its capabilities, we tested the probe intraoperatively in 53 infants and children undergoing surgical repair of congenital heart disease, and found that clear echocardiographic images with good detail were provided, including the ability to image coronary arteries in patients weighing as little as 2.7 kg. Imaging detail transesophageally is commensurate with the performance of this system from a transthoracic route. This probe also has the capacity for accurate estimates of high velocity jets using continuous-wave Doppler, which is a relatively new development.
最近开发了一种用于儿科患者的经食管探头，它包含48个而非26个元件，并允许连续波多普勒以及脉冲和彩色多普勒血流模式。该探头可能会显著提高图像质量。为了评估其性能，我们在53例接受先天性心脏病手术修复的婴儿和儿童中进行了术中测试，发现可以提供具有良好细节的清晰超声心动图图像，包括对体重低至2.7 kg的患者的冠状动脉进行成像的能力。经食管成像的细节与该系统经胸途径的性能相当。该探头还能够使用连续波多普勒准确估计高速射流，这是一个相对较新的进展。
