【摘要】：目的分析右房容积指数(RAVI)在经导管射频消融术联合心腔内电复律治疗持续性心房颤动(AF)及其远期复发中的应用价值。方法选取在我院行多步骤递进式消融(包括环肺静脉隔离+线性隔离+碎裂电位消融)后,AF仍未终止,术中再行心腔内电复律治疗的持续性AF患者66例。将术前7d内和术后12~48个月的超声心动图及临床资料进行对比研究,尤其对RAVI进行重点分析。结果所有患者术后均转复为窦性心律。根据是否远期复发,将患者分为复发组(23例)和未复发组(43例)。复发组的RAV、RAVI和AF病程均显著高于未复发组(P0.05),两组间差异有统计学意义。LVMI、LAV、LAVI在两组间差异无统计学意义(P0.05)。两组患者的临床资料比较差异均无统计学意义(P0.05)。结论经导管射频消融术联合心腔内电复律可将持续性AF成功转为窦性心律。RAVI可反映持续性AF术后RA结构的改变。
[Abstract]:Objective to analyze the effect of right atrial volume index (RAVI) in the treatment of persistent atrial fibrillation (AF) by transcatheter radiofrequency ablation combined with intracardiac electrocardiography (ECR). Methods multistep progressive ablation (including annular pulmonary vein isolation linear isolated fragmentation potential ablation) was performed in our hospital. 66 patients with persistent AF were treated with intracardiac electrocardiogram during operation. Echocardiography and clinical data of 7 days before operation and 12 ~ 48 months after operation were compared. Results all the patients recovered to sinus rhythm after operation according to the long term recurrence. The patients were divided into recurrent group (23 cases) and non-recurrence group (43 cases). The course of RAVRAVI and AF in recurrent group was significantly higher than that in non-recurrence group (P 0.05). The difference between the two groups was statistically significant. There was no significant difference in LAVI between the two groups (P 0.05). There was no significant difference in clinical data between the two groups (P 0.05). Conclusion Transcatheter radiofrequency ablation combined with intracardiac cardioversion can successfully convert persistent AF into sinus rhythm. RAVI can reflect the changes of RA structure after persistent AF.
