Atrial septal defect (ASD) is a common structural congenital heart disease. With the development of interventional closure devices and transcatheter techniques, interventional closure therapy has become the most well-accepted therapeutic alternative worldwide, as it offers a number of advantages over conventional therapies such as improved safety, easier operation, lower complication rates and invasiveness, and shorter anesthetic time and hospitalizations. During the past decades, various types of occluders based on nondegradable shape memory alloys have been used in clinical applications. Considering that the permanent existence of foreign nondegradable materials in vivo can cause many potential complications in the long term, the research and development of biodegradable occluders has emerged as a crucial issue for interventional treatment of ASD. This review aims to summarize partially or fully biodegradable occlusion devices currently reported in the literature from the aspects of design, construction, and evaluation of animal experiments. Furthermore, a comparison is made on the advantages and disadvantages of the materials used in biodegradable ASD occlusion devices, followed by an analysis of the problems and limitations of the occlusion devices. Finally, several strategies are proposed for future development of biodegradable cardiac septal defect occlusion devices. STATEMENT OF SIGNIFICANCE: Although occlusion devices based on nondegradable alloys have been widely used in clinical applications and saved numerouspatients, biodegradable occlusion devices may offer some advantages such as fewer complications, acceptable biocompatibility, and particularly temporary existence, thereby leaving "native" tissue behind, which will certainly become the development trend in the long term. This review summarizes almost all partially or fully biodegradable occlusion devices currently reported in the literature from the aspects of design, construction, and evaluation of animal experiments. Furthermore, a comparison is made on the advantages and disadvantages of the materials used in biodegradable ASD occlusion devices, followed by an analysis of the problems and limitations of the occlusion devices. Finally, several strategies are proposed for future development of biodegradable cardiac septal defect occlusion devices.

可生物降解的房间隔缺损封堵器:当前的审查。

房间隔缺损(ASD)是一种常见的结构性先天性心脏病。随着介入闭合装置和经导管技术的发展,介入闭合疗法已成为世界上最广为接受的治疗替代方案,因为它比常规疗法具有许多优势,例如,安全性更高,操作更简便,并发症发生率和侵入性更低,以及缩短麻醉时间和住院时间。在过去的几十年中,基于不可降解形状记忆合金的各种类型的封堵器已用于临床。考虑到长期存在的外国不可降解物质在体内可能长期引起许多潜在的并发症,可生物降解封堵器的研究和开发已成为介入治疗ASD的关键问题。这篇综述的目的是从动物实验的设计,构造和评估方面总结目前文献中报道的部分或全部可生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。意义声明:尽管基于不可降解合金的咬合装置已在临床应用中广泛使用,并挽救了无数患者,可生物降解的闭塞装置可提供一些优点,例如并发症更少,可接受的生物相容性,特别是暂时存在,从而留下“天然”组织,从长远来看,这无疑将成为发展趋势。这篇综述从动物实验的设计,构造和评估方面总结了目前文献中报道的几乎所有可部分或全部生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。可接受的生物相容性,尤其是暂时存在的生物相容性,从而留下“天然”组织,从长远来看,这无疑将成为发展趋势。这篇综述从动物实验的设计,构造和评估方面总结了目前文献中报道的几乎所有可部分或全部生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。可接受的生物相容性,尤其是暂时存在的生物相容性,从而留下“天然”组织,从长远来看,这无疑将成为发展趋势。这篇综述从动物实验的设计,构造和评估方面总结了目前文献中报道的几乎所有可部分或全部生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。从长远来看,这必将成为发展趋势。这篇综述从动物实验的设计,构造和评估方面总结了目前文献中报道的几乎所有可部分或全部生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。从长远来看,这必将成为发展趋势。这篇综述从动物实验的设计,构造和评估方面总结了目前文献中报道的几乎所有可部分或全部生物降解的闭塞装置。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。此外,对可生物降解的ASD闭塞装置中使用的材料的优缺点进行了比较,然后分析了闭塞装置的问题和局限性。最后,为可生物降解的心脏间隔缺损闭塞装置的未来发展提出了几种策略。
