To assess the results of transcatheter ablation of cardiac arrhythmias in Latin America and establish the first Latin American transcatheter ablation registry.
All ablation procedures performed between 1 January and 31 December 2012 were analysed retrospectively. Data were obtained on the characteristics and resources of participating centres (public or private institution, number of beds, cardiac surgery availability, type of room for the procedures, days per week assigned to electrophysiology procedures, type of fluoroscopy equipment, availability and type of electroanatomical mapping system, intracardiac echo, cryoablation, and number of electrophysiologists) and the results of 17 different ablation substrates: atrio-ventricular node reentrant tachycardia, typical atrial flutter, atypical atrial flutter, left free wall accessory pathway, right free wall accessory pathway, septal accessory pathway, right-sided focal atrial tachycardia, left-sided focal atrial tachycardia, paroxysmal atrial fibrillation, non-paroxysmal atrial fibrillation, atrio-ventricular node, premature ventricular complex, idiopathic ventricular tachycardia, post-myocardial infarction ventricular tachycardia, ventricular tachycardia in chronic chagasic cardiomyopathy, ventricular tachycardia in congenital heart disease, and ventricular tachycardias in other structural heart diseases. Data of 15 099 procedures were received from 120 centres in 13 participating countries (Argentina, Bolivia, Brazil, Chile, Colombia, Cuba, El Salvador, Guatemala, Mexico, Peru, Dominican Republic, Uruguay, and Venezuela). Accessory pathway was the group of arrhythmias most frequently ablated (31%), followed by atrio-ventricular node reentrant tachycardia (29%), typical atrial flutter (14%), and atrial fibrillation (11%). Overall success was 92% with the rate of global complications at 4% and mortality 0.05%.
Catheter ablation in Latin America can be considered effective and safe.
评估拉丁美洲经导管消融治疗心律失常的结果，并建立首个拉丁美洲经导管消融注册库。
对2012年1月1日至12月31日期间进行的所有消融手术进行回顾性分析。收集了参与中心的特征和资源数据（公立或私立机构、床位数、心脏外科手术可用性、手术房间类型、每周分配给电生理手术的天数、荧光透视设备类型、电解剖标测系统的可用性和类型、心内超声、冷冻消融以及电生理学家数量）以及17种不同消融基质的结果：房室结折返性心动过速、典型心房扑动、非典型心房扑动、左游离壁旁道、右游离壁旁道、间隔旁道、右侧局灶性房性心动过速、左侧局灶性房性心动过速、阵发性心房颤动、非阵发性心房颤动、房室结、室性早搏、特发性室性心动过速、心肌梗死后室性心动过速、慢性恰加斯心肌病室性心动过速、先天性心脏病室性心动过速以及其他结构性心脏病室性心动过速。从13个参与国家（阿根廷、玻利维亚、巴西、智利、哥伦比亚、古巴、萨尔瓦多、危地马拉、墨西哥、秘鲁、多米尼加共和国、乌拉圭和委内瑞拉）的120个中心收到了15099例手术的数据。旁道是最常消融的心律失常组（31%），其次是房室结折返性心动过速（29%）、典型心房扑动（14%）和心房颤动（11%）。总体成功率为92%，全球并发症发生率为4%，死亡率为0.05%。
拉丁美洲的导管消融可被认为是有效且安全的。
