Isolated left ventricular noncompaction (LVNC) is a rare disorder caused by embryonic arrest of compaction. LVNC is sometimes associated with other congenital cardiac disorders; however, there have been few reports of its coexistence with a left ventricular aneurysm. A 40-year-old woman was admitted to our hospital for renal infarction. She had a history of embolic cerebral infarction 10 years ago. Transthoracic echocardiography showed prominent trabeculae and deep intertrabecular recesses which are filled with blood from the left ventricular (LV) cavity. A thrombus in the akinetic apical wall was confirmed by contrast echocardiography. Using cardiac computed tomography and magnetic resonance imaging, we rejected a possible diagnosis of suspicion of coronary artery disease. She was diagnosed LVNC with a thrombus in apical aneurysm. Here, we report the first patient in Korea known to have LVNC accompanying LV congenital aneurysm presenting with recurrent embolism.
孤立性左心室心肌致密化不全（LVNC）是一种由致密化胚胎停滞引起的罕见疾病。LVNC有时与其他先天性心脏疾病相关；然而，其与左心室动脉瘤共存的报道很少。一名40岁女性因肾梗死入住我院。她10年前有栓塞性脑梗死病史。经胸超声心动图显示突出的小梁和深陷的小梁间隐窝，这些隐窝充满了来自左心室腔的血液。对比增强超声心动图证实运动减弱的心尖壁有血栓形成。通过心脏计算机断层扫描和磁共振成像，我们排除了疑似冠状动脉疾病的可能诊断。她被诊断为LVNC伴心尖动脉瘤内血栓形成。在此，我们报告韩国首例已知患有LVNC并伴有左心室先天性动脉瘤且表现为反复栓塞的患者。
