A patent foramen ovale (PFO) is detected frequently by transesophageal echocardiography. The diagnosis of paradoxical embolism is usually presumptive when arterial emboli occur in the appropriate clinical setting. Presumably, paradoxical embolism of small thrombi arise in the venous system and pass through the PFO during a transient right-to-left shunt; however, cases demonstrating a thrombus traversing the PFO are relatively few.
经食管超声心动图常常能检测到卵圆孔未闭（PFO）。当在合适的临床环境中出现动脉栓塞时，反常栓塞的诊断通常是推测性的。据推测，小血栓的反常栓塞起源于静脉系统，并在短暂的右向左分流期间穿过卵圆孔未闭；然而，显示血栓穿过卵圆孔未闭的病例相对较少。
