Abstract: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, left pulmonary vein and left interauricular crest width in patients with recurrent atrial fibrillation after pulmonary vein isolation. Transesophageal echocardiography can provide valuable information for clinical ablation of atrial fibrillation.
