Predictors of life-threatening events in adult patients with left ventricular noncompaction

Figure 1 Visual, electrocardiographic, and morphological features of left ventricular noncompaction. A and B: Electrocardiogram indicated low QRS voltage and non-sustained ventricular tachycardia; C and D: Echocardiogram indicated left ventricular noncompaction including a thrombus in the apex of left ventricle and intertrabecular blood flow by Doppler; E: Cardiac computed tomography indicated that the ratio of noncompact and compact myocardium was more than 2.3; F: Endomyocardial biopsy of the right ventricle. Hematoxylin and eosin staining indicated lymphocytic infiltration and necrosis as a sign of myocarditis.
