Massive aneurysmal dilatation of the foramen ovale was diagnosed angiocardiographically in a patient with tricuspid atresia. The angiographic findings are distinct for this condition, and the pathogenesis appears to be related to a restrictive atrial communication in the patient with obligatory right to left shunting at atrial level. The anatomic potential for atrial restriction in the patient with tricuspid or pulmonary atresia, intact ventricular septum and diminutive right ventricle necessitates balloon atrial septostomy at the initial diagnostic cardiac catheterization. In the patient with aneurysmal dilatation of the foramen ovale, satisfactory decompression may be achieved by Blalock-Hanlon atrial septectomy, open atrial septectomy, or, possibly, balloon septostomy.
通过心血管造影术诊断出一名三尖瓣闭锁患者的卵圆孔存在巨大动脉瘤样扩张。这种情况的血管造影表现独特，其发病机制似乎与该患者心房水平存在强制性右向左分流时的限制性心房交通有关。对于三尖瓣或肺动脉闭锁、室间隔完整且右心室较小的患者，由于存在心房受限的解剖学可能性，在初次诊断性心导管检查时需要进行球囊房间隔造口术。对于卵圆孔存在动脉瘤样扩张的患者，可通过布莱洛克 - 汉隆房间隔切除术、开放性房间隔切除术或可能的球囊造口术实现满意的减压。
