A case of total anomalous pulmonary venous connection to the portal vein is described. The diagnosis was suspected clinically, supported by the echocardiogram, and confirmed by cardiac catheterisation, angiocardiography, and contrast echocardiography. An echo-free space lying behind the left atrium initially was thought to represent the common pulmonary vein. However, contrast echocardiography showed that this space was not the anomalous vein but probably an artefact. This paper shows that the origins of intracardiac echoes cannot always be assumed from a simple comparison of echocardiography with angiocardiographic or necropsy findings. In some cases it is necessary to introduce a marker into the echocardiogram which unequivocally originates from, and, therefore, localises, the structure under examination. Contrast echocardiography provides such a marker.
本文描述了一例完全性肺静脉异位连接至门静脉的病例。临床怀疑该诊断，超声心动图提供了支持，心脏导管检查、心血管造影及对比超声心动图得以确诊。最初认为左心房后方的无回声区代表共同肺静脉。然而，对比超声心动图显示该区域并非异常静脉，可能是一种假象。本文表明，不能仅通过简单对比超声心动图与心血管造影或尸检结果来推断心内回声的起源。在某些情况下，有必要在超声心动图中引入一个明确源自被检查结构并能对其进行定位的标记物。对比超声心动图可提供这样一种标记物。
