A patient with recent inferior myocardial infarction with right ventricular involvement developed severe hypoxemia unresponsive to 100% oxygen. Contrast two-dimensional echocardiography revealed right to left shunting through an aneurysmal fossa ovalis with a patent foramen ovale. This was confirmed by cardiac catheterization. Surgical closure of the defect was probably life-saving. This case report illustrates that right to left shunting through a foramen ovale should be considered in the differential diagnosis of hypoxemia in patients presenting with inferior myocardial infarction.
一名近期发生下壁心肌梗死并累及右心室的患者出现严重低氧血症，对100%氧气治疗无反应。对比二维超声心动图显示通过伴有卵圆孔未闭的瘤样卵圆窝存在右向左分流。心脏导管检查证实了这一点。手术闭合该缺损可能挽救生命。本病例报告表明，对于出现下壁心肌梗死的低氧血症患者，在鉴别诊断时应考虑通过卵圆孔的右向左分流。
