摘　　要：【目的】探讨心脏超声的相关参数对房颤射频消融(RAOAF)术后再发中的评估价值。【方法】选择2016年2月至2018年1月在本院诊治的66例RAOAF患者.依据术后是否复发分为复发组(观察组)和未复发组(对照组),比较两组心脏超声的相关参数,Cox回归分析RAOAF术后再发房颤的影响因素。【结果】66例患者有32例患者复发,占48.48%。观察组左房大小、二尖瓣瓣环收缩期收缩峰值速度(s′)显著大于对照组,二尖瓣瓣环舒张晚期峰值速度(A′).舒张早期峰值速度(E′)显著小于对照组.其差异均有统计学意义(P<0.05),但两组左室射血分数(LVEF)、左心室大小、左心室后壁厚度及右心室前后径比较差异无统计学的意义(P>0.05).多因素Cox回归分析显示:A′是RAOAF术后再发的独立预测因子.【结论】心脏超声的相关参数中A'对RAOAF术后再发的评估有一定的参考价值,值得临床重视。[Objective]To study the value of cardiac ultrasonography-related parameters in the evaluation of recurrence after radiofrequency ablation of atrial fibrillation (RAOAF).[Methods]A total of 66 patients with RAOAF who were treated in our hospital from February 2016 to January 2018 were enrolled in the recurrence group (observation group) and the non-recurrent group (control group). Cox regression analysis were performed to reveal the influencing factors of recurrent atrial fibrillation after RAC )AF.[ Results ] Of the 66 patients, 32 had recurrence, acco un ting for 48.48%. The left atrial size and systolic peak velocity of the mitral annulus (s′) in the observation group were significantly greater than those of the control group, while the peak velocity of the mitral annulus at late diastolic phase (A′), and the peak of early diastolic velocity (E) were significantly smaller than those of the control group. The differences were statistically significant ( P <0.05). There were no significant differences in left ventricular ejection fraction (LVEF), left ventricular size, left ventricular posterior wall thickness, and right ventricular anteroposterior diameter between the two groups ( P >0.05). Multivariate Cox regression analysis showed that A′peak value was an in dependent risk factor of recurrence after RAOAF.[Concl usion] Among the parameters related to cardiac ultrasound. A peak value has certain reference value for the evaluation of postoperative recurrence of RAOAF, and is worthy of special attention.
