Left atrial appendage closure aims to eliminate the stasis component of Virchow triad by eliminating a cul-de-sac that favors thrombosis, particularly when atrial contractility becomes inefficient, such as in atrial fibrillation. Left atrial appendage closure devices have a common objective of sealing the appendage completely, with device stability and avoidance of device thrombosis. Two main device designs have been used to perform left atrial appendage closure: those that use a pacifier design (lobe + disk) and those that use a plug (single lobe) design. This review highlights the potential features and benefits of the single-lobe devices.
左心耳封堵术旨在通过消除有利于血栓形成的死腔来消除维科三要素中的停滞成分，特别是在心房收缩力变得低效时，如在心房颤动中。左心耳封堵装置的共同目标是完全封闭心耳，保证装置的稳定性并避免装置血栓形成。有两种主要的装置设计被用于执行左心耳封堵术：一种是使用奶嘴设计（瓣叶+盘），另一种是使用塞子（单个瓣叶）设计。本综述强调了单瓣叶装置的潜在特点和优势。
