Central venous pressure monitoring line insertion is routine prior to the conduct of cardiac surgery, and in rare instances, malposition can contribute to operative complications. We describe here how a central venous line lying in the right atrium became caught in a left atrial (LA) closure suture during a mitral valve replacement. The opening of the LA suture line is highly unsafe without cardiopulmonary bypass (CPB) because of the possibility of systemic air embolism, but by employing an ingenious method of suturing over and unravelling the continuous sutures closing the left atrium, it was possible to surgically retrieve it without the use of a CPB.
在进行心脏手术前，插入中心静脉压监测线是常规操作，在极少数情况下，位置不当可能会导致手术并发症。我们在此描述了在二尖瓣置换术中，一根位于右心房的中心静脉线如何被左心房（LA）关闭缝线缠住。由于存在系统性空气栓塞的可能性，在没有体外循环（CPB）的情况下，LA缝线开口是非常不安全的，但通过采用一种巧妙的方法，在缝合并解开关闭左心房的连续缝线的同时进行缝合，可以在不使用CPB的情况下通过手术取出该静脉线。
