心脏异位(Malposition of the heart)是指心脏及其内部结构在胸腔内的位置异常,可伴有或不伴有胸腹腔其他内脏的位置异常。可分为右位心、左旋心及中位心三种。定义右位心(Deatrocardia):心脏的主要部分及心尖在右侧胸腔内,心脏的长轴(心底部至心尖的联线)指向右下。左旋心(Levoversion,Levorotation)亦称孤立性左位心(Isolated Levocardia):心脏的主要部分及心尖在左侧胸腔内,心脏的长轴指向左下,而内脏呈部分性或完全性反位(Inversion)或异位(He terotaxia)。
Malposition of the heart (Malposition of the heart) refers to the internal structure of the heart and its internal abnormalities in the chest cavity, with or without the other organs of the chest and abdomen abnormalities in the position. Can be divided into right centripetal, left ventricular and centripetal three. DEFINITIONS Deatrocardia: The major part of the heart and apex of the heart are within the right chest, and the long axis of the heart (bottom of heart to apex) points to the lower right. Levoversion (Levotation), also known as isolated Levocardia: the main part of the heart and apex in the left chest, the long axis of the heart pointing to the lower left, and visceral partial or complete anti-bit (Inversion ) Or He terotaxia.
