摘要

左心室不充盈(LVNC)通常被描述为一种先天性心肌病,其特征是突出的心肌小梁和在左心室腔内延伸的深层小梁间凹陷。从无症状到出现心力衰竭和其他严重并发症,临床表现差异很大。诊断通常需要通过二维经胸超声心动图或心脏磁共振检查。此外,即使 LVNC 患者的应变参数明显降低,也没有进行常规检查。在此,我们报告了一例因肺水肿入院的无症状患者。二维经胸超声心动图显示其患有严重的瓣膜性心脏病,左心室有明显的小梁和重塑,但斑点追踪超声心动图(STE)仅显示其应变轻度降低。因此,我们探讨了 STE 可用于区分 LVNC 心肌病和严重重塑导致的 LVNC 表型的可能性。

Left Ventricle Noncompaction Phenotype: Cause or Consequence?

Left ventricular noncompaction (LVNC) is commonly described as a congenital cardiomyopathy characterized by prominent myocardial trabeculae and deep intertrabecular recesses extending in the left ventricular chamber. Clinical presentation can differ considerably from asymptomatic individuals to those presenting with heart failure and other serious complications. Diagnosis is usually made by two-dimensional transthoracic echocardiography or cardiac magnetic resonance. Moreover, even if strain parameters are significantly reduced in patients with LVNC, they are not routinely investigated. Here, we report the case of a previously symptomless patient admitted to the hospital for pulmonary edema. Two-dimensional transthoracic echocardiography showed severe valvular heart disease and left ventricle pronounced trabeculation and remodeling, although speckle tracking echocardiography (STE) demonstrated only mild strain reduction. We, therefore, explore the possibility that STE may be useful to differentiate LVNC cardiomyopathy from LVNC phenotype due to severe remodeling.
