A 58-year-old man presented with left ventricular failure. Coronary angiography revealed normal coronary arteries and endomyocardial biopsy from the right ventricular apex was normal. Echocardiogram showed marked trabeculation and deep intertrabecular recesses most prominent in the left ventricular apex, anterior and the lateral wall. Cine magnetic resonance imaging showed double-layered appearance on long-axis, 4-chamber and short-axis views. These findings were consistent with isolated noncompaction of the ventricular myocardium (INVM). Gadolinium-diethylenetriomine pentaacetic acid-enhanced imaging revealed delayed enhancement in the both left and right ventricular myocardium.
一位 58 岁男性因左心衰竭就诊。冠状动脉造影显示冠状动脉正常，右心室心尖部的心肌活检也正常。超声心动图显示左心室心尖部、前壁和侧壁有明显的心肌小梁化和深小梁间凹陷。电影磁共振成像显示长轴、四腔心和短轴视图上的双层外观。这些发现与孤立性心室心肌致密化不全（INVM）一致。钆喷替酸葡甲胺增强成像显示左、右心室心肌均有延迟强化。
