Paroxysmal atrial arrhythmias especially atrial fibrillation are frequently encountered in adult patients with atrial septal defect. However, the diagnosis of atrial defect can be difficult. Thransthoracic echocardiography, the mostly utilized cardiac technique, has shown a limited ability to identify small atrial defects. Transesophageal echocardiography has shown high accuracy to identify but it isn't well tolerated of the patients. Recently, the utility of multislice computed tomography in the evaluation of direction, location, and size of shunt flow in congenital heart disease has been demonstrated. Cardiac magnetic resonance imaging (MRI) is a recent imaging technique that permits with high spatial resolution and without ionising radiation an accurate identification of many cardiovascular diseases. We report an unusual detection of an atrial defect by phase-contrast cine MRI in a patient clinically suspected of arrhitmogenic right ventricular displasia.
阵发性房性心律失常尤其是心房颤动在患有房间隔缺损的成年患者中经常出现。然而，房间隔缺损的诊断可能很困难。经胸超声心动图是最常用的心脏检查技术，但已显示出识别小房间隔缺损的能力有限。经食管超声心动图显示出较高的识别准确率，但患者耐受性不佳。最近，多层计算机断层扫描在评估先天性心脏病分流的方向、位置和大小方面的效用已得到证实。心脏磁共振成像（MRI）是一种最新的成像技术，它能够以高空间分辨率且无需电离辐射来准确识别多种心血管疾病。我们报告了一例通过相位对比电影MRI意外检测到房间隔缺损的病例，该患者临床上怀疑患有致心律失常性右心室发育不良。
