Sinus venosus atrial septal defect (ASD) accounts for 5% to 10% of ASDs. In contrast with the more common superior vena cava (SVC) type, the inferior vena cava (IVC) type of sinus venosus ASD with overriding IVC is extremely rare. The sinus venosus defect occur posterior to the fossa ovalis and is not regarded as true ASD. Transesophageal echocardiography (TEE) is a diagnostic procedure of choice due to close proximity of atrial septum to TEE transducer. However; it may not constantly yield detailed anatomical and functional characterization, and other imaging modalities such as cardiac magnetic resonance imaging (MRI) may be needed. We report the case of a 45-year-old woman with an undiagnosed hemodynamically significant IVC-type ASD without any anomalous drainage of pulmonary veins, who presented with progressive dyspnea.
静脉窦型房间隔缺损（ASD）占房间隔缺损的5%至10%。与更常见的上腔静脉（SVC）型不同，下腔静脉（IVC）型静脉窦型ASD伴下腔静脉骑跨极为罕见。静脉窦缺损发生在卵圆窝后方，不被视为真正的ASD。经食管超声心动图（TEE）是首选的诊断方法，因为房间隔与TEE换能器距离很近。然而，它可能无法持续提供详细的解剖和功能特征，可能需要其他成像方式，如心脏磁共振成像（MRI）。我们报告了一例45岁女性病例，该患者患有未被诊断出的具有血流动力学意义的IVC型ASD，且无任何肺静脉异常引流，表现为进行性呼吸困难。
