摘　　要：目的应用经食管超声心动图(TEE)评价心房颤动患者环肺静脉电隔离术后复发的肺静脉及左心房肺静脉嵴部宽度的变化。方法选取2014年10月~2016年8月海南省三亚市人民医院心内科环肺静脉电隔离的术后复发患者48例,经食管超声测量环肺静脉隔离术前1周内、术后48 h、术后5个月左上、左下、右上、右下肺静脉口直径及左心房肺静脉嵴部宽度的变化。结果术后5个月左上、左下、右上及右下肺静脉口直径与术前1周内、术后48 h比较,差异有统计学意义(P<0.05);术后48 h左上、左下、右上、右下肺静脉口直径及左心房最大容积、最小容积与术前1周内比较,差异均无统计学意义(均P>0.05);术后5个月左心房最大容积、最小容积与术前1周内、术后48 h比较,差异无统计学意义(P>0.05);术后48 h左肺静脉与左心耳间嵴宽度与术前1周内比较,差异有统计学意义(P<0.05);术后5个月左肺静脉与左心耳间嵴宽度与术前1周内比较,差异无统计学意义(P>0.05);术后5个月左肺静脉与左心耳间嵴宽度与术后48 h比较,差异有统计学意义(P<0.05)。结论心房颤动肺静脉隔离术后复发患者的肺静脉口、左房容积以及左肺静脉与左心耳间嵴宽度未出现增大。经食管超声能为临床医师消融心房颤动提供一定有价值的信息。Objective To evaluate the changes of pulmonary vein and left atrial pulmonary vein crest width in patients with atrial fibrillation after loop pulmonary vein electrical isolation by transesophageal echocardiography. Methods Forty-eight cases of postoperative recurrence patients in the Department of Cardiology, Sanya People′ s Hospital, Hainan Province were selected from October 2014 to August 2016. Changes in the diameter of the left superior, left inferior, right superior, right inferior pulmonary vein opening and left atrial pulmonary vein crest width were measured by esophageal ultrasound within 1 week before ring pulmonary vein isolation, 48 h after surgery and 5 months after surgery. Results Five months after the operation, the diameter of the left superior, the left inferior, the right superior and the right inferior pulmonary vein opening were compared with that of the 1 week before the operation and 48 h after the operation, and the difference was statistically significant(P < 0.05);48 h after surgery, the diameter of left upper, left lower, right upper, right lower pulmonary vein opening, and the maximum and minimum volume of left atrium showed no statistically significant difference compared with that within 1 week before surgery(all P > 0.05). There was no statistically significant difference between the maximum and minimum volume of left atrium at 5 months after surery and that within 1 week before operation and 48 h after surery(P > 0.05). The difference between the ridge width of left pulmonary vein and left atrial appendage was statistically significant(P < 0.05). There was no significant difference in the interauricular ridge width between left pulmonary vein and left atrial appendage between 5 months and 1 week before surery(P >0.05);5 months after surery, the left pulmonary vein and left interauricular crest width were compared with 48 h after surgery, and the differences were statistically significant(P < 0.05). Conclusion There is no increase in pulmonary vein orifice, left atrial volume, le
