This case illustrates the Eustachian valve as an ambiguous entity. By tethering a thrombus the valve prevented a major pulmonary embolism. However, in combination with a patent foramen ovale, it directs the thrombus into the left atrium, creating a threat for systemic embolisms.
该病例表明，咽鼓管瓣膜是一个具有不确定性的结构。通过拴住血栓，该瓣膜预防了一次严重的肺栓塞。然而，它与卵圆孔未闭共同作用时，会将血栓导向左心房，从而产生发生系统性栓塞的风险。
