目的:对影响心房颤动导管消融术后3个月内复发患者直流电复律成功率的因素进行回顾性研究。方法:连续入选2010年11月至2011年11月,在北京安贞医院心内科二病房行持续性心房颤动导管消融术,且在术后3个月内因持续性房性心律失常住院行电复律的患者。禁食状态下,地西泮静脉注射镇静,行双向同步直流电复律,除颤电极片置于心尖区及胸骨旁右侧,能量依次采用50~200J。结果:共入选63例患者,年龄33~69岁,平均心房颤动病史14.6个月,左心房直径(42.8±5.2)mm,左心室射血分数(62.9±5.3)%。复发持续性心律失常中46%为心房扑动,54%为心房颤动,共进行97次电复律。患者即刻复律成功率为77%,其中80%一次放电复律成功。在年龄、性别、合并疾病、左心室射血分数、术前是否服用心律平等方面,即刻复律成功组与即刻失败组相比,两组间差异无统计学意义(P>0.05)。单因素分析示年龄、左心房扩大心房颤动持续时间与电复律即刻成功率显著相关。进行Logistic回归分析校正上述因素后发现,术前心房颤动持续时间(OR=0.957,95%CI:0.921~0.994,P=0.023)和术前服用胺碘酮是复律成功率的独立预测因素。即刻成功的定义是复律后维持窦性心律>24 h。结论:心房颤动导管消融术后早期复发的患者,术前心房颤动持续时间和术前服用胺碘酮是电复律即刻成功的独立预测因素。  相似文献

目的对持续性心房颤动导管消融术后1个月内复发快速房性心律失常患者,比较早期直流电复律治疗与早期消融治疗的临床效果,为临床决策提供证据,并对持续性房颤早期复发早期消融电生理特点进行分析。方法回顾性分析2010年6月至2011年6月121例首次消融术后1个月内复发房性心动过速的持续性房颤患者,其中早期电复律69例,早期二次消融52例,平均随访(11±5)个月,分析两组的临床效果及手术组二次手术电生理特点。结果 69例早期复律患者平均随访(11±5)个月,14例维持窦性心律。52例手术患者平均随访(10±4)个月,24例维持窦性心律,早期手术组成功率较早期复律组高(46.2%比20.3%,P=0.002)。Logistic回归分析发现,左心房大小及治疗手段是房颤二次复发的独立影响因素。电生理检查发现,52例早期手术患者中,33例(63%)有肺静脉电位恢复。左上肺静脉电位恢复最多,为16支。其余肺静脉电位恢复情况分别为:左下肺静脉14支;右上肺静脉12支;右下肺静脉10支。结论持续性房颤早期复发进行早期二次消融成功率较早期电复律高。肺静脉电位恢复是持续性房颤早期复发的常见现象。  相似文献

目的分析导管消融术联合心腔内电复律治疗非阵发性心房颤动(房颤)远期复发的影响因素。方法选取2009年1月至2014年12月上海交通大学医学院附属新华医院行多步骤递进式消融后,房颤仍未终止,术中再经静脉导管心腔内电复律法进行电复律的非阵发性房颤患者62例。随访12~48个月,对可能影响远期复发的因素进行分析。结果经导管消融术后持续房颤发作的所有非阵发性房颤患者,经静脉导管心腔内电复律治疗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(26例)和未复发组(36例)。复发组患者的房颤病程显著长于未复发组[60(0.25,360)个月比24(0.25,120)个月,P=0.019],左心室重量指数[(150.16±34.48)g/m~2比(132.97±27.33)g/m~2,P=0.033]、左心房容积[(75.33±32.03)ml比(59.51±22.36)ml,P=0.025]、左心房容积指数[(40.70±15.81)ml/m~2比(32.21±12.76)ml/m~2,P=0.023]均显著高于未复发组,差异均有统计学意义。多因素回归分析显示,房颤病程是术后远期复发的独立危险因素(OR1.017,95%CI 1.003~1.032,P=0.017)。结论导管消融术联合经静脉导管心腔内电复律可将非阵发性房颤成功转复为窦性心律,房颤病程是患者远期复发的独立危险因素。  相似文献

Outcomes of Cardioversion Post AF Ablation.   Introduction: Early recurrence of atrial tachyarrhythmias is commonly noted after catheter ablation of atrial fibrillation (AF). The long-term outcomes of patients who require cardioversion for persistent AF after AF ablation is not known. This study reports the outcomes of patients who underwent cardioversion for persistent AF or atrial flutter following an AF ablation procedure.
Methods: The patient population comprised 55 patients (mean age 58 ± 10 years, 35% paroxysmal) who underwent catheter ablation of AF and subsequently required electrical cardioversion for persistent AF (45 patients) or atrial flutter (10 patients). Cardioversion was defined as early (within 90 days of the ablation procedure) or late (between 90 and 180 days following ablation).
Results: The mean follow-up duration was 15 ± 8 months. Forty-six of the 55 patients (84%) patients experienced recurrence during follow-up. The average time to recurrence after cardioversion was 37 days. Of the 55 patients, 8 (15%) patients had a complete success, 11 (20%) patients had a partial success and 36 patients (65%) had a failed outcome. Seven of the 43 patients (16%) who underwent early cardioversion had a complete success as opposed to one of 12 patients (8%) who underwent late cardioversion (P = 0.49).
Conclusions: This study shows that >80% of patients who undergo cardioversion for persistent AF or atrial flutter after AF ablation have recurrence. The timing of cardioversion did not affect the outcome. These findings allow clinicians to provide realistic expectations to patients regarding the long-term outcome and/or requirement for a second ablation procedure.

Introduction: It is unclear whether early restoration of sinus rhythm in patients with persistent atrial arrhythmias after catheter ablation of atrial fibrillation (AF) facilitates reverse atrial remodeling and promotes long‐term maintenance of sinus rhythm. The purpose of this study was to determine the relationship between the time to restoration of sinus rhythm after a recurrence of an atrial arrhythmia and long‐term maintenance of sinus rhythm after radiofrequency catheter ablation of AF. Methods and Results: Radiofrequency catheter ablation was performed in 384 consecutive patients (age 60 ± 9 years) for paroxysmal (215 patients) or persistent AF (169 patients). Transthoracic cardioversion was performed in all 93 patients (24%) who presented with a persistent atrial arrhythmia: AF (n = 74) or atrial flutter (n = 19) at a mean of 51 ± 53 days from the recurrence of atrial arrhythmia and 88 ± 72 days from the ablation procedure. At a mean of 16 ± 10 months after the ablation procedure, 25 of 93 patients (27%) who underwent cardioversion were in sinus rhythm without antiarrhythmic therapy. Among the 46 patients who underwent cardioversion at ≤30 days after the recurrence, 23 (50%) were in sinus rhythm without antiarrhythmic therapy. On multivariate analysis of clinical variables, time to cardioversion within 30 days after the onset of atrial arrhythmia was the only independent predictor of maintenance of sinus rhythm in the absence of antiarrhythmic drug therapy after a single ablation procedure (OR 22.5; 95% CI 4.87–103.88, P < 0.001). Conclusion: Freedom from AF/flutter is achieved in approximately 50% of patients who undergo cardioversion within 30 days of a persistent atrial arrhythmia after catheter ablation of AF.  相似文献

Early Recurrence After AF Ablation. Background: Atrial tachycardia (AT) commonly recurs within 3 months after radiofrequency catheter ablation for atrial fibrillation (AF). However, it remains unclear whether early recurrence of atrial tachycardia (ERAT) predicts late recurrence of AF or AT. Methods: Of 352 consecutive patients who underwent circumferential pulmonary vein isolation with or without linear ablation(s) for AF, 56 patients (15.9%) with ERAT were identified by retrospective analysis. ERAT was defined as early relapse of AT within a 3‐month blanking period after ablation. Results: During 21.7 ± 12.5 months, the rate of late recurrence was higher in patients with ERAT (41.1%) compared with those without ERAT (11.8%, P < 0.001). In a multivariable model, positive inducibility of AF or AT immediately after ablation (65.2% vs 36.4%, P = 0.046; odd ratio, 3.9; 95% confidence interval, 1.0–14.6) and the number of patients who underwent cavotricuspid isthmus (CTI) ablation (73.9% vs 42.4%, P = 0.042; odd ratio, 4.5; 95% confidence interval, 1.1–19.5) were significantly related to late recurrence in the ERAT group. The duration of ablation (174.3 ± 62.3 vs 114.7 ± 39.5 minutes, P = 0.046) and the procedure time (329.3 ± 83.4 vs 279.2 ± 79.7 minutes, P = 0.027) were significantly longer in patients with late recurrence than in those without late recurrence following ERAT. Conclusions: The late recurrence rate is higher in the patients with ERAT compared with those without ERAT following AF ablation, and is more often noted in the patients who underwent CTI ablation and had a prolonged procedure time. Furthermore, inducibility of AF or AT immediately after ablation independently predicts late recurrence in patients with ERAT.

Very Early Recurrence of AF. Introduction: Early restoration of sinus rhythm following ablation of atrial fibrillation (AF) facilitates reverse atrial remodeling and improves the long‐term outcome. The purpose of this study was to determine the predictors and outcome in patients with very early AF recurrences (< 2 days). Methods and Results: Ablation was performed in 339 consecutive AF patients (paroxysmal AF = 262). Biatrial voltage was mapped during sinus rhythm. If recurrent AF occurred within 2 days following the ablation, electrical cardioversion was performed to restore sinus rhythm. Very early recurrences of AF occurred in 39 (15%) patients with paroxysmal AF and 26 (34%) with nonparoxysmal AF. Patients with very early recurrence had a higher incidence of nonparoxysmal AF (40% vs 18.6%, P< 0.001), requirement of electrical cardioversion during procedure, larger left atrial (LA) diameter (43 ± 7 vs 39 ± 6 mm, P< 0.001), lower left ventricular ejection fraction (54 ± 10% vs 59 ± 7, P< 0.001), longer procedural time, and lower LA voltage (1.5 ± 0.7 vs 1.9 ± 0.8 mV, P< 0.001). A multivariate analysis revealed that the independent predictors of a very early recurrence were a longer procedural time and lower LA voltage. During a follow‐up of 13 ± 5 months, a very early recurrence did not predict the long‐term outcome of a single procedure recurrence in the patients with paroxysmal AF, but was associated with a late recurrence in the nonparoxysmal AF patients. Conclusion: Very early recurrence occurred in patients with paroxysmal AF is not associated with long‐term recurrence. Nonparoxysmal AF is an independent predictor of late recurrence of AF in patients with very early recurrence. (J Cardiovasc Electrophysiol, Vol. pp. 1‐6)  相似文献

Background Two important limitations of the data regarding the outcomes of catheter ablation of atrial fibrillation (AF) are the short-term follow-up used in most published studies and the lack of single-procedure outcomes.Objective The objective was to report the long-term single-procedure outcomes at our center.Materials and methods The patient population was comprised of 200 consecutive patients who underwent ablation (133 men; age 56 ± 11 years). Atrial fibrillation was paroxysmal in 92 (46%). Success was defined as absence of symptomatic AF, off antiarrhythmic drug (AAD) after a single procedure.Results After a follow-up of 26 ± 11 months, the single-procedure long-term success rate was 28% with an additional 7% of patients demonstrating improvement. After including repeat procedures in 64 patients, the overall long-term success rate was 41% with 11% demonstrating improvement. Further subgroup analysis of 48 paroxysmal AF patients considered to be optimal candidates for the procedure, revealed a long-term success rate of 69% with an additional 4% demonstrating improvement. A major complication occurred in 7.9% of patients.Conclusion The results reveal that the long-term single-procedure success rate of catheter ablation of AF in a cohort of patients with predominantly non-paroxysmal AF is less than 40%. The inclusion of redo procedures resulted in an improvement in outcomes. A much higher success rate of 69% was achieved in patients with paroxysmal AF considered to be optimal candidates for this procedure. These results make it clear that further advances in the technique of catheter ablation of AF are needed to improve the safety and efficacy of this procedure. In order to be able to compare outcomes of various techniques in differing patient populations, we urge investigators to report long-term single procedure outcomes.This study was supported by The Norbert and Louise Grunwald Cardiac Arrhythmia Research Fund.  相似文献
