Abstract
Objective To evaluate the changes of left atrial structure and function in the patients with atrial fibrillation who accepted bi -polar radio frequency current ablation .Methods All patients in our study were divided into three groups including the ones who had accept -ed bipolar radio frequency current ablation because of atrial fibrillation ,the ones who refused to accept ablation operation in despite of atrial fibrillation and the ones who maintained sinus rhythm before operation .All patients accepted TTE before and after operation .Results The rate of transverse diameter change of ablation group (24.24 ±8.67)%was larger than those of other two groups (P<0.05).Left atrial chan-nel capacity volume change rate of ablation group (17.18 ±3.26)%were larger than the values of the group who were suffering atrial fibrilla-tion but refused ablation advice (0.86 ±0.26)(P<0.05).Left atrial total ejection fractions of ablation group (202.41 ±81.59)%were lar-ger than the values of the group who were suffering atrial fibrillation but refused ablation advice (109.53 ±60.91)%( P<0.05) .And its ac-tive ejection fractions(12.18 ±3.48)%,total ejection fractions(41.31 ±8.26)%and so forth were less than the group who maintained si-nus rhythm before operation(21.33 ±5.61)%,(45.05 ±7.37)%,respectively (P<0.05).Left atrial posterior wall center and cardiac basal segment strain(14.34 ±9.47)%,(13.20 ±8.38)%,respectively,and strain rate values after operation of ablation group were less than other segments .Conclusion Left atrial structure remodeling inversion was not obviously 3~6 months after bipolar radio frequency cur-rent ablation .And at the same time ,the improvement of left atrial storage function was not obviously compared with the group who refused ab -lation advice,left atrial channel function compensation degree descended obviously left atrial co -pumping function in ablation group increased obviously,left atrial posterior wall center and cardiac basal segment systolic and distolic function were less than other segments of left .关键词
