目的 探讨左心室肌致密化不全的临床及超声心动图特点。方法 分析左心室肌致密化不全临床表现、心电图、胸片、超声心动图特点。结果 左心功能不全 3例 ,肾栓塞 1例 ;室性期前收缩 2例 ;超声心动图均发现左心室腔内二尖瓣水平、腱索水平或乳头肌水平以下的心肌被网格状或蜂窝状的海绵样心肌组织所充填 ,可合并先天性心脏畸形。结论 左心室肌致密化不全临床上可表现为左心功能不全 ,室性心律失常及心内膜血栓伴系统栓塞 ,超声心动图是诊断本病的首选方法。
Objective To investigate the clinical and echocardiographic features of left ventricular hypertrophy. Methods The clinical manifestations of densification of left ventricular muscle, electrocardiogram, chest radiograph and echocardiography were analyzed. Results Left ventricular dysfunction in 3 cases, renal embolism in 1 case; ventricular premature contractions in 2 cases; echocardiography were found in the left ventricular cavity mitral valve level, chordae tendinosis or below the level of myocardium is grid or Honeycomb-like sponge-like myocardial tissue filling can be combined with congenital heart disease. Conclusion The densification of left ventricular muscle can be clinically manifested as left ventricular dysfunction, ventricular arrhythmia and endocardial thrombosis with systemic embolism. Echocardiography is the first choice for the diagnosis of this disease.
