左房容积指数对导管射频消融术后房颤复发的预测价值

摘要

Objective To investigate the the value of left atrial volume index in predicting late recurrence of atrial fibrillation (AF) after catheter ablation.Methods 52 patients who had undergone RFCA were followed up for 12 months.Clinical variables which could affect recurrence of atrial fibrillation after catheter ablation were analyzed.Results All of the 52 patients had completed the CPVA procedure ( 1 patient was lost).At the end of one year follow-up, 39 patients were successfully treated without AF recurrence.12 patients ( 23.53％ ) suffered from atrial fibrillation recurrence.Compared with that of unrecurrence group, left atrial diameter (LAD) and left atrial volume index (LAVI) of recurrence group decreased significantly.There was no significant difference between the recurrence group and unrecurrence group in age, sex, EF and heart disease ( P ＜ 0.05 or ＜ 0.01 ).Logistic regression analysis revealed that the only indepedent predictor for the recurrence of atrial fibrillation was LAVI (P ＜0.01 ).Conclusions Compared with LAD, LAVI is a better parameter for predicting recurrence of atrial fibrillation.%目的 探讨左房容积指数(LAVI)对导管射频消融术(RFCA)后房颤(AF)复发的预测价值.方法 对52例行RFCA的AF患者随访12个月,分析RFCA后AF复发的影响因素.结果 52例患者均完成CPVA,达到消融终点;随访12个月时未复发39例,复发12例(23.53%),1例失访.复发与未复发者比较,其年龄、性别、左室射血分数、是否合并器质性心脏病无统计学差异,左房直径及LAVI有统计学差异(P＜0.05或＜0.01);Logistic多元回归分析显示,LAVI为AF复发的独立危险因素(P＜0.01).结论 与左房直径比较,LAVI是更好的预测RFCA后AF复发的因素.
