Transcatheter closure of atrial septal defect (ASD) in children is now an accepted treatment as an alternative to surgery. We report a case of complete atrioventricular block (AVB) observed over several days after closure of an ASD with an Amplatzer Septal Occluder(®) in a 13-year-old child. The spontaneous outcome was good with regression of the complete AVB, but 1 year later, a first-degree AVB was still present. The use of large devices in young children and a small postero-inferior rim seem to be risk factors of AVB. Transcatheter closure of ASD requires close monitoring of cardiac rhythm.
经导管封堵儿童房间隔缺损（ASD）现已成为一种可接受的替代手术的治疗方法。我们报告了一例13岁儿童使用Amplatzer房间隔封堵器（®）封堵ASD后数天内出现完全性房室传导阻滞（AVB）的病例。完全性AVB自行消退，预后良好，但1年后仍存在一度AVB。在幼儿中使用大型装置以及较小的后下缘似乎是AVB的危险因素。经导管封堵ASD需要密切监测心律。
