Abstract

A 62-year-old woman with a history of heart failure, hypertension and stroke presented to hospital with dyspnea. Transthoracic echocardiography revealed significant left ventricular dysfunction; with contrast-enhanced 2- and 3-dimensional echocardiography, extensive hypetrabeculation of the left ventricular myocardium was visualized, leading to a diagnosis of noncompaction cardiomyopathy. Apical thrombi were excluded with contrast imaging; however, the patient was systemically anticoagulated owing to the presence of noncompaction cardiomyopathy in the setting of prior stroke. This case report demonstrates remarkable imaging of the left ventricular myocardium achieved with contrast-enhanced 3-dimensional echocardiography in the setting of noncompaction cardiomyopathy.

摘要

一名有心力衰竭、高血压和中风病史的62岁女性因呼吸困难入院。经胸超声心动图显示左心室功能严重受损；通过对比增强二维和三维超声心动图，可见左心室心肌广泛的肌小梁增多，从而诊断为致密化不全型心肌病。对比成像排除了心尖血栓；然而，由于患者既往有中风史且存在致密化不全型心肌病，因此进行了全身抗凝治疗。本病例报告展示了在致密化不全型心肌病情况下，对比增强三维超声心动图对左心室心肌的显著成像效果。
