Percutaneous transvenous closure of atrial septal defects (ASDs) has become feasible in recent years, as later-generation devices have largely overcome initial difficulties in device deployment and complication rates. The Amplatzer septal occluder (ASO) is one such device that we have used extensively and is, in our opinion, the most versatile and practical to use. It is capable of closing defects up to 40 mm in diameter via a relatively low-profile delivery sheath. More importantly, the ASO may be easily withdrawn into the sheath after deployment but prior to release, which is essential in safely closing difficult defects where successful positioning on the initial deployment is not guaranteed. In this article based on our experience, review of the literature, and communications with other operators, we describe the various problems encountered in closing atrial septal defects and make suggestions as to the best way of overcoming these difficulties.
近年来，经皮经静脉闭合房间隔缺损（ASD）已变得可行，因为新一代装置在很大程度上克服了最初在装置植入方面的困难以及并发症发生率问题。Amplatzer房间隔封堵器（ASO）就是我们广泛使用的这样一种装置，并且在我们看来，它是使用起来最通用、最实用的。它能够通过相对较细的输送鞘管闭合直径达40毫米的缺损。更重要的是，ASO在植入后但释放前可轻松撤回鞘管内，这对于安全闭合难以确保首次植入就能成功定位的复杂缺损至关重要。在本文中，基于我们自身的经验、文献回顾以及与其他操作者的交流，我们描述了在闭合房间隔缺损过程中遇到的各种问题，并就克服这些困难的最佳方法提出建议
