Key echocardiographic assessments during percutaneous atrial septal defect (ASD) closure are the maximal defect diameter, the presence or absence of tissue rims, and the spatial relationships between the implanted device and cardiac structures. These assessments drive device selection and may help identify situations that may place a patient at risk for device erosion or other complications. On-line three-dimensional (3D) transesophageal echocardiography (TEE) enables the rendering of nearly unlimited tissue planes within an acquired pyramidal-shaped volume with minimal image post-processing. We present several cases of percutaneous ASD closure guided by on-line 3D TEE imaging that highlight the potential advantages of this new imaging technology.
经皮房间隔缺损（ASD）封堵术期间的关键超声心动图评估包括最大缺损直径、组织边缘的存在与否，以及植入装置与心脏结构之间的空间关系。这些评估结果决定了器械的选择，并有助于识别可能使患者面临器械侵蚀或其他并发症风险的情况。在线三维（3D）经食管超声心动图（TEE）能够在获得的金字塔形体积内呈现几乎无限数量的组织平面，且图像后处理最小化。我们展示了几例经皮 ASD 封堵术，这些病例由在线 3D TEE 成像引导，突出了这种新成像技术的潜在优势。
