Echocardiographic findings are described in a patient with hypoplastic right heart syndrome (pulmonary atresia type with intact ventricular septum and small right ventricular cavity) who had an associated atrial septal aneurysm. An unusual appearance of echoes behind the aorta bulging into the left atrium in diastole on both the M-mode and cross-sectional echo suggested this diagnosis prior to cardiac catheterization. The angiographic findings confirmed the diagnosis of right ventricular hypoplasia, pulmonary atresia and the large atrial septal aneurysm. The infant died after surgery and the atrial septal aneurysm was observed at autopsy. The importance of the diagnosis of the atrial septal aneurysm and its association with restriction of right-to-left atrial shunting prompts this report.
本文描述了一名患有右心发育不全综合征（室间隔完整、右心室腔小的肺动脉闭锁型）且伴有房间隔瘤患者的超声心动图检查结果。在心脏导管插入术之前，M型和横截面超声心动图均显示舒张期主动脉后方有异常回声突入左心房，提示了这一诊断。血管造影结果证实了右心室发育不全、肺动脉闭锁和巨大房间隔瘤诊断。该婴儿术后死亡，尸检时观察到房间隔瘤。房间隔瘤的诊断及其与右向左心房分流受限的关联的重要性促使了本报告的发表。
