目的:探讨心肌致密化不全心脏彩色B超临床诊断。方法:选择我院收治的心肌致密化不全患者11例,临床表现为心慌、胸闷、气喘、气短、呼吸困难、疲乏,2例伴有下肢浮肿,初步诊断为扩张性心肌病3例,冠心病5例,3例待查,所有患者出现不同类型心律失常的心电图改变。采用美国GE公司生产的Vivid7彩色多普勒超声诊断仪对患者进行二维、M型以及多方位、多切面观察心脏。结果:11例患者经超声心动图检查均为左室受累,病变部位:心尖部、侧壁中下段、侧壁合并下壁、侧壁合并心尖部,左房内径28～63mm,左室内径50～76mm,心肌厚度3～6mm。4例合并室性心律失常,3例合并二尖瓣反流,4例合并三尖瓣反流。结论:彩色多普勒超声心动图能够在无症状的阶段即可以发现心肌结构异常的特征性改变,对不明原因的心肌病或心脏增大患者及时进行彩色多普勒超声心动图检查,采取相应的治疗措施,预防致死性心律失常和栓塞,延长患者的生存期。
Objective: To investigate the ultrasonographic diagnosis of cardiac hypertrophy without color Doppler. Methods: Eleven patients with myocardial densification insufficiency admitted to our hospital were selected. The clinical manifestations were palpitation, chest tightness, asthma, shortness of breath, difficulty breathing and fatigue. The edema of lower extremities was found in 2 patients. The initial diagnosis was dilated cardiomyopathy in 3 and coronary heart disease 5 cases, 3 cases pending investigation, all patients showed different types of arrhythmia ECG changes. Using Vivid7 color Doppler ultrasonic diagnostic apparatus produced by GE of the United States, the patients were observed two-dimensional, M-type and multi-directional, multi-sectioned to observe the heart. Results: Eleven patients had left ventricular involvement by echocardiography. The lesion included apical part, middle and lower part of lateral wall, inferior wall and side wall combined with apical part. The diameter of left atrium was 28-63mm and the diameter of left ventricle was 50 ~ 76mm, myocardial thickness 3 ~ 6mm. 4 patients with ventricular arrhythmia, 3 patients with mitral regurgitation, 4 patients with tricuspid regurgitation. CONCLUSIONS: Color Doppler echocardiography can detect characteristic changes of cardiac structural abnormalities during the asymptomatic phase. Color Doppler echocardiography should be performed in time for patients with unexplained cardiomyopathy or cardiac enlargement. Correspondingly, The treatment measures to prevent lethal arrhythmia and embolism, prolong the survival of patients.
