摘要
目的探讨慢性房颤患者射频消融术后左心房、左心室远期结构变化。方法 50例经射频消融治疗的房颤患者根据复发情况分为复发组(n=18)与未复发组(n=32),对比两组患者术前、术后12个月左房前后径、左右径、上下径,左心房最大容积、左心室舒张末期内径、左心室收缩末期内径、左室射血分数。结果术前、术后随访12个月比较左房前后径、左右径、上下径,左心房最大容积、左心室舒张末期内径、左心室收缩末期内径、左室射血分数比较,复发组差异无统计学意义(P>0.05),未复发组差异具有统计学意义(P<0.05)。结论射频消融术治疗房颤具有显著疗效,复律并维持窦性心律对于逆转左心房、左心室重构,提高左室功能均具有重要意义。
Objective To explore the long - term changes of left atrial and ventricular structure after radiofrequency ablation in patients with chronic atrial fibrillation. Methods Fifty patients with chronic atrial fibrillation treated with radiofrequency ablation were divided into the re- current group （ n = 18 ） and the non - recurrent group （ n = 32）, then the anteroposterior diameter, transverse diameter, top to bottom diameter of left atrium, left atrial maximum volume, left ventricular end - diastolic diameter, left ventricular end - systolic diameter and left ventricular ejec- tion fraction before and 12 months after the treatment were contrasted between the two groups. Results There was no significantly difference in an- teroposterior diameter, transverse diameter, top to bottom diameter of left atrium, left atrial maximum volume, left ventricular end - diastolic diam- eter, left ventricular end - systolic diameter and left ventrieular ejection fraction before and 12 months after radiofrequeney ablation in the recurrent group （ P 〉0.05 ） ; however, significantly differences in these parameters were found in the non -recurrent group before and 12 months after the treatment （ P 〈 0.05）. Conclusion Radiofrequency ablation is effective for atrial fibrillation. Cardioversion and maintenance of sinus rhythm are important for the reversal of left atrium and left ventricle remodeling and improving left ventricular function.
