An adequate interatrial communication is necessary to accommodate right atrial output in patients with tricuspid atresia. We report a patient with a tiny opening in the midportion of the atrial septum, who was found to have an anomalous systemic venous to left atrial communication. This channel was not evident on noninvasive testing, but would likely have caused persistent desaturation following a Fontan procedure had it not been detected. In patients with restrictive interatrial communications, an angiogram of the right atrium may reveal similar anomalous channels.
对于三尖瓣闭锁患者，足够的心房内交通对于容纳右心房输出是必要的。我们报告了一名患者，其房间隔中部有一个微小开口，发现存在异常的体静脉至左心房交通。该通道在非侵入性检查中不明显，但如果未被检测到，在Fontan手术后可能会导致持续的血氧饱和度降低。对于房间隔交通受限的患者，右心房血管造影可能会显示类似的异常通道。
