Double-inlet left ventricle (DILV) is a congenital heart disease that only a single left ventricle and a rudimentary right ventricle are developed. Because of lack of anatomic landmark, interpretation of Tl myocardial perfusion imaging in DILV is essentially challenging for unusual anomaly. We report the case of a 44-year-old woman with DILV who presented exertional dyspnea and tachycardia and underwent Tl SPECT. The anatomic characteristics of cardiac Tl SPECT are correlated with MRI. To obtain accurate interpretation in DILV, it is absolutely necessary to realize the anatomy relationship between perfusion imaging and anatomic imaging such as CT or MRI.
双入口左心室(DILV)是一种先天性心脏病，只有一个左心室和一个基本的右心室发育。由于缺乏解剖学标志，Tl 心肌灌注成像在 DILV 中的解释对于异常异常来说本质上是具有挑战性的。我们报告了一例 44 岁的女性 DILV 患者，表现为劳力性呼吸困难和心动过速，并进行了 Tl SPECT。心脏 Tl SPECT 的解剖特征与 MRI 相关。为了在 DILV 中获得准确的解释，绝对有必要认识到灌注成像与 CT 或 MRI 等解剖成像之间的解剖关系。
