We report a young patient with post traumatic acquired thoracic aortic coarctation in whom three-dimensional transthoracic echocardiography (3DTTE) demonstrated incremental value over two-dimensional transthoracic echocardiography (2DTTE). 3DTTE showed (1) en face views of the obstruction site that showed a markedly narrowed, roughly circular orifice measuring 0.33 cm(2) in area, (2) echogenic tissue encroaching on the graft lumen consistent with fibrosis/thrombus, and (3) no graft protrusion into the aortic lumen, only hypermobility of the medial portion of the graft. These important findings were not detected by 2DTTE.
我们报告了一名患有创伤后获得性胸主动脉缩窄的年轻患者，在该患者中，三维经胸超声心动图（3DTTE）显示出比二维经胸超声心动图（2DTTE）更大的价值。3DTTE显示：（1）梗阻部位的正面视图，显示出一个明显狭窄、面积约为0.33平方厘米的大致圆形开口；（2）与纤维化/血栓相符的回声组织侵入移植物管腔；（3）没有移植物突入主动脉管腔，只有移植物内侧部分的活动度增加。这些重要发现2DTTE未能检测到。
