Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

In case 9, the heart is globally enlarged (Figure 11). This can result from, or be present in, many different conditions,43 such as endocardial fibroelastosis, fetal anemia,44 storage disorders, ischemia,45 infections,46,47 atrioventricular and semilunar valve regurgitation after tachycardia, and an atrioventricular block.

这个病例呈现为全心扩大（图11），这种情况可以是由多种疾病引发，也可存在于多种疾病中，比如心内膜纤维弹性组织增生、胎儿贫血、储存障碍、局部缺血、感染、心动过速引发的房室瓣和半月瓣反流以及房室传导阻滞。
