The prevalence of atrial septal aneurysm (ASA) in a general referral population of patients was investigated by use of transthoracic (TTE) and transesophageal echocardiographies (TEE). Contrast TEE was performed to detect interatrial shunting in patients with ASA. In this population, the prevalence of ASA as determined by TTE was 0.47% (24/5,079), and 0.78% (40/5,079) by TEE. Of these 40 patients 16 (40%) were judged to be normal by TTE. Of the forty patients who were positive for ASA, 50% demonstrated interatrial shunting (atrial septal defects, 10; patent foramen ovale, 10). The authors concluded that TEE is of significant value in detecting the presence of ASA and associated cardiac abnormalities. Contrast TEE further enhances the detection of interatrial shunting in patients with ASA.
通过经胸超声心动图（TTE）和经食管超声心动图（TEE）对普通转诊患者人群中心房隔瘤（ASA）的患病率进行了调查。对患有ASA的患者进行对比TEE以检测心房分流。在该人群中，TTE确定的ASA患病率为0.47%（24/5079），TEE确定的患病率为0.78%（40/5079）。在这40例患者中，16例（40%）经TTE判断为正常。在40例ASA呈阳性的患者中，50%表现为心房分流（房间隔缺损10例；卵圆孔未闭10例）。作者得出结论，TEE在检测ASA的存在及相关心脏异常方面具有重要价值。对比TEE进一步提高了对患有ASA患者心房分流的检测。
