Abstract:
Objective To explore the important anatomic structures associated with pulmonary veins and similar sections to transthoraeic echocardiography using 64一slice spiral CT and tO locate the pulmonary veins on echocardiography. Methods The transthoracic echocardiography and 64-slice spiral CT were performed in 12 patients with atrial fibrillation.The 3-dimensional information of four pulmonary veins on CT was analyzed and the relationship between the locations of four pulmonary veins and adjacent anatomic structures were observed.The comparison of CT and echocardiography for assessing the location of pulmonary veins was performed.Results All of the pulmonary veins were demonstrated optimally without abnormal structures and anatomic variations.The ostium of right superior pulmonary vein adjoined the atrial septum and the proximal of the right superior pulmonary vein was near to the superior vena cava.The right inferior superior pulmonary was a little bit far from atrial septum.The left superior pulmonary vein adjoined the left atrial auricle.The left inferior pulmonary vein was a little bit far from the 1eft atrial auricle and adjoined the thoracic descending aorta.According to adjusting the angle of the probe on echocardiography,the four pulmonary veins could be demonstrated in the standard parasternal left ventricular long-axis view, parasternal short-axis view and apical four chamber view.The non-standard views assisted in identifying the pulmonary veins.Conclusions Transthoracic echocardiography can demonstrate all the four pulmonary veins and also locate the spatial location based on the adjacent anatomic structures.
