中国经导管消融治疗心房颤动注册研究-2007

Objective To report the outcome of registered cathered catheter ablation of atrial fibrillation (AF) in China 2007. Methods Data on AF ablation from registered hospitals in 2007 was analyzed retrospec-tively. Results A total of 2620 cases from 40 hospitals wererecruied,male 1719,female 901 ,mean age 58.5± 11.2years. Proportions of patients with paroxysmal, long-standing permanent AF were 77.4% ,15.7% and 6.9%, respectively. Patients accompanied with underlying disease were 54.1%. Left atrial diameter was (38.3 ± 6.3) mm,left ventricular end-diastolic dimension was(47.8 ±5.2)ram,and left ventricular ejection fraction waa 0.63 ±0.08. The most common prcedures were circumferential pulmonary veins (PV) ablation and circumferential PV ablation plus additional hnes. The most often used ablation energy was radiofrequency (99.8%). Total success rate was 80.3% ,and recurrence rate was 19.7%. Factors impacting success and rencurrence rates included left atrial diameter,type of AF,and procedures. After catheter ablation,antiarrhythmic drug application increased mod-erately,and the anticoagulation therapy stengthened. Complications occurred in 26 patients (1.7%), no severe coplications such as esophagus atrail fistula and pulmonary vein stenosis were observed. Conclusions The catheter ablation could be recommended as a first-line therapy for patients with symptomatic paroxsmal AF in qualified hospitals.

递进式消融法治疗持续性心房颤动的初步体会

Objective To evaluate the effect of catheter ablation on persistent atrial fibrillation (AF) using step-wise approach. Methods Thirty-four patients [mean age (54.8 ± 11.4) years] with persistent AF [mean (36.5 ± 9.8) months] underwent catheter ablation were enrolled. Ablation was performed in following sequence. Circumferential ablation of pulmonary veins to achieve isolation, linear ablation of left atrium roof and mitral isthmus, ablation at sites possessing complex fractionated atrial electrograms. Using activation Carto mapping system, if AF converted to atrial flutter (AFL) or atrial tachycardia (AT), then catheter ablation was applied to terminate tachycardia. Results The step-wise ablation approach was successful in rhythm changes (AF converted to AFL/AT) in 88.2% of patients, 61.8% of patients conversion to sinus rhythm directly via ablation. At 12.6 ±6.2 months of follow-up, 82.4% of patients were maintained in sinus rhythm (42.9% of those patients taking oral amiedarone). Conclusion Catheter ablation using step-wise approach is effective in persistent AF treatment.
