(tt2624) M, 59 y. Mechanical AV prosthesis (Carbomedics #25) (Fig 1-2). Vascular graft in ascending aorta (Fig. 5). Linear artifact in the LA cavity (Fig 3-4; white short arrow in Fig. 4), replicating the anterior wall of the vascular graft: the distance between the transducer and the artifact doubles approximately the distance between the transducer and the anterior aortic wall (53 mm).
主动脉瓣机械人造瓣(Carbomedics #25) (图1-2)。升主动脉人工血管 (图5)。左房腔中的线形伪影(图3-4; 图4中的白色短箭头), 重复了人工血管的前壁: 探头到伪影的距离大约是探头到主动脉前壁的二倍 (53 mm)。
