Cardiac tamponade can manifest as profound hypoxemia from intracardiac shunting across a patent foramen ovale. As a consequence, pulmonary embolus can be erroneously diagnosed. As demonstrated in the case described herein, transesophageal echocardiography can be useful in determining the correct diagnosis, especially if transthoracic echocardiography is technically limited. In our patient, the findings on transesophageal echocardiography also helped determine the appropriate treatment. The relative inaccessibility of the pericardial effusion to needle drainage prompted open surgical drainage.
心脏压塞可表现为经未闭卵圆孔的心脏内分流导致的严重低氧血症。因此，可能会错误地诊断为肺栓塞。正如本文所述病例所示，经食管超声心动图有助于确定正确诊断，特别是在经胸超声心动图在技术上受限的情况下。在我们的患者中，经食管超声心动图的检查结果也有助于确定适当治疗。心包积液难以通过穿刺引流，这促使进行开放手术引流。
