证明通过三维 (3D) 经食管超声心动图 (TEE) 准确测量三尖瓣环面积的临床可行性，并根据三尖瓣反流 (TR) 的存在评估几何差异。此外，还将三尖瓣环的形状与文献中先前的描述进行了比较。预期。三级护理大学医院。三维TEE。接受心脏手术的患者。通过 3D TEE 获取 20 名患者的体积数据集并进行前瞻性分析。根据 TR 的存在，对各组之间的环形几何形状进行比较。 QLab（飞利浦医疗系统，安多弗，马萨诸塞州）软件包用于通过线性椭圆尺寸和平面测量法计算三尖瓣环面积。在 4D Cardio-View（TomTec Corporation GmBH，德国慕尼黑）和 MATLAB（马萨诸塞州纳蒂克）软件环境中进行了进一步分析，以准确评估环形形状。研究发现，TR 较大的患者具有偏心扩张的瓣环，瓣环面积也较大。此外，与平面测量法相比，线性椭圆法测量的面积被高估。此外，作者开发的数学模型证实了三尖瓣环的不规则鞍形几何形状。三维 TEE 可用于以临床可行的方式测量三尖瓣环面积，在 TR 患者中观察到偏心扩张。三尖瓣环形状复杂，具有环形高点和低点，基于线性测量的环形面积计算明显高估了 3D 平面面积。
To demonstrate the clinical feasibility of accurately measuring tricuspid annular area by 3-dimensional (3D) transesophageal echocardiography (TEE) and to assess the geometric differences based on the presence of tricuspid regurgitation (TR). Also, the shape of the tricuspid annulus was compared with previous descriptions in the literature. Prospective. Tertiary care university hospital. Three-dimensional TEE. Patients undergoing cardiac surgery. Volumetric data sets from 20 patients were acquired by 3D TEE and prospectively analyzed. Comparisons in annular geometry were made between groups based on the presence of TR. The QLab (Philips Medical Systems, Andover, MA) software package was used to calculate tricuspid annular area by both linear elliptical dimensions and planimetry. Further analyses were performed in the 4D Cardio-View (TomTec Corporation GmBH, Munich, Germany) and MATLAB (Natick, MA) software environments to accurately assess annular shape. It was found that patients with greater TR had an eccentrically dilated annulus with a larger annular area. Also, the area as measured by the linear ellipse method was overestimated as compared to the planimetry method. Furthermore, the irregular saddle-shaped geometry of the tricuspid annulus was confirmed through the mathematic model developed by the authors. Three-dimensional TEE can be used to measure the tricuspid annular area in a clinically feasible fashion, with an eccentric dilation seen in patients with TR. The tricuspid annulus shape is complex, with annular high and low points, and annular area calculation based on linear measurements significantly overestimates 3D planimetered area.
