【摘要】：目的：本研究旨在探讨心房颤动患者行环肺静脉电隔离术前后应用经食道超声心动图检测左房结构和各肺静脉直径的变化。方法：30例接受环肺静脉电隔离术心房颤动患者,分别于术前24-48小时,术后24-48小时(近期),术后3个月(远期)应用经食道超声心动图测量左上、左下、右上、右下四个肺静脉直径及右下肺静脉血流速度,左房嵴宽变化,同时测量左房内径、左房长径、左房横径。结果：1.左上、左下、右上肺静脉直径术后24-48小时较术前明显减小(P0.05),术后3个月基本恢复到术前状态,左下肺静脉直径术后3月较术后24-48小时增大(P0.05)。右下肺静脉术后24-48小时较术前有所减小,但无统计学意义(P0.05),右下肺静脉血流速度术后24-48小时较术前明显增快(P0.01),术后三个月较术后24-48小时有所减慢(P0.05),较术前有所增快,但无统计学意义(P0.05)；肺静脉嵴部宽度术后24-48小时较术前明显增宽(P0.01),术后3个月较术后24-48小时明显减小(P0.01),基本恢复到术前状态,且比术前有减小趋势,但无统计学意义(P0.05)。2.与术前相比,术后三月左房内径、横径、长径均明显缩小(P0.01),术后24-48小时左房内径、横径及长径则无明显变化。结论：1.环肺静脉电隔离术近期内会引起左房肺静脉嵴变宽,远期逐渐变窄并较术前有所改善,同时造成左上、右上、左下肺静脉近期内变窄,远期内逐渐恢复,与术前无明显变化。2.左房内径、横径、长径术后三个月较术前及术后24-48小时逐渐缩小,术后24-48小时较术前则无明显变化。
[Abstract]:Objective: to investigate the changes of left atrial structure and pulmonary vein diameter in patients with atrial fibrillation by transesophageal echocardiography before and after cyclic pulmonary vein isolation. Methods Twenty patients with atrial fibrillation underwent cyclic pulmonary vein isolation were measured by transesophageal echocardiography at 24 to 48 hours before operation, 24 to 48 hours after operation (short term, 3 months after operation). The diameter of the four right inferior pulmonary veins, the velocity of the right inferior pulmonary vein and the width of the left atrial crest were measured, and the diameter of the left atrium, the long diameter of the left atrium and the transverse diameter of the left atrium were measured at the same time. The result is 1: 1. The diameter of left upper, lower left and right superior pulmonary vein decreased significantly 24-48 hours after operation than that before operation, and the diameter of left inferior pulmonary vein returned to the preoperative state 3 months after operation, and the diameter of left inferior pulmonary vein increased in 3 months after operation than that in 24-48 hours after operation. The right inferior pulmonary vein decreased 24-48 hours after operation, but there was no significant difference (P 0.05). The blood flow velocity of right inferior pulmonary vein was significantly faster at 24-48 hours after operation than that before operation (P 0.01), and slowed down at 3 months after operation than that at 24 to 48 hours after operation, which was faster than that before operation. However, there was no significant difference in the width of pulmonary vein ridge between 24-48 hours after operation and that before operation (P 0.01a), 3 months after operation significantly decreased P0.01a, and basically returned to the preoperative state, and there was a decreasing trend as compared with that before operation, but there was no significant difference in the width of pulmonary vein between 24 and 48 hours after operation (P0.05U. 2). Compared with pre-operation, left atrial diameter, transverse diameter and long diameter decreased significantly in 3 months after operation, while left atrial diameter, transverse diameter and long diameter did not change at 24-48 hours after operation. Conclusion 1. In the near term, the left atrial pulmonary vein crest will become wider, narrow and improve in the long term. At the same time, the left upper, upper right and lower left pulmonary veins will become narrower in the short term, and gradually recover in the long term, and there is no significant change in the long term. 2. The internal diameter, transverse diameter and long diameter of left atrium gradually decreased in 3 months after operation compared with those before operation and 24 to 48 hours after operation, but there was no significant change between 24 and 48 hours after operation.
