Rotation of the heart results from enlargement of individual cardiac chambers and influences significantly the configuration of the cardiomediastinal silhouette. Left ventricular enlargement leads to dextrorotation. Conversely, right ventricular enlargement leads to levorotation. The axis of rotation is nearly vertical and extends from the top of the aortic arch through the anterior wall of the left atrium and the proximal interventricular septum. Pericardial defect, deformity of the thoracic skeleton, and lower lobe atelectasis can also lead to cardiac rotation. An understanding of this concept facilitates the interpretation of chest radiographs in patients with heart disease. The terms clockwise and counterclockwise rotation of the heart should be abandoned.
心脏旋转是由各个心腔扩大引起的，对心纵隔轮廓的形态有显著影响。左心室扩大导致右旋。相反，右心室扩大导致左旋。旋转轴几乎是垂直的，从主动脉弓顶部穿过左心房前壁和室间隔近端。心包缺损、胸廓骨骼畸形和下叶肺不张也可导致心脏旋转。了解这一概念有助于解读心脏病患者的胸部X线片。应摒弃心脏顺时针和逆时针旋转的术语。
