Purpose of the review

Percutaneous closure of sinus venosus atrial septal defects (ASD) using covered stent implantation is a new and promising minimally invasive technique. New imaging tools are used to ensure preoperative anatomical characterization and preoperative guidance, which are key procedural success factors. Here we will describe and analyze these recent developments.

Recent findings

Sinus venosus ASDs present a wide variety of anatomical features which must be described and analyzed using various imaging tools, including 3D technology. Percutaneous closure is challenging, but can hasten clinical recovery compared to the gold-standard conventional open-heart surgery. The feasibility of percutaneous closure relies on precise preoperative anatomical study and on real-time guidance using a multimodal fusion imaging process.

Summary

Three-dimensional modeling of sinus venosus ASD is essential to understand the large anatomical panel encountered in this pathology. Multimodal fusion imaging guidance is very useful for performing sinus venosus ASD percutaneous closure in selected patients.

静脉窦 ASD：成像和经皮闭合

审查目的

使用覆膜支架植入术经皮缝合窦静脉房间隔缺损 (ASD) 是一种新的、有前途的微创技术。新的成像工具用于确保术前解剖特征和术前指导，这是关键的手术成功因素。在这里，我们将描述和分析这些最近的发展。

最近的发现

静脉窦 ASD 具有多种解剖特征，必须使用各种成像工具（包括 3D 技术）进行描述和分析。经皮闭合具有挑战性，但与金标准的常规心脏直视手术相比，可以加速临床恢复。经皮闭合的可行性依赖于精确的术前解剖学研究和使用多模态融合成像过程的实时引导。

概括

静脉窦 ASD 的三维建模对于理解这种病理学中遇到的大型解剖面板至关重要。多模态融合成像引导对于在选定的患者中进行静脉窦 ASD 经皮闭合非常有用。
