心肌致密化不全心脏彩色B超临床诊断分析

Clinical Diagnostic Analysis of Echocardiography in Noncompaction of Ventricular Myocardium

目的：我们通过深部研究探讨心脏组织肌肉致密化不全的心脏彩色B型超声的临床诊断和应用价值。方法：从2009至2011年间入住我院的心肌致密不全的22例患者,患者的临床症状主要表现为心慌、胸闷（胸痛）、胸闷气短,神疲乏力,动则尤剧,心悸怔忡,眠少多梦,口干少饮,或伴眩晕耳鸣。其中4例有双下肢轻至重度浮肿,入院后的诊断为扩张性心肌病6例,冠心病10例,6例待查,这些患者将出现不同类型心律失常的心图改变（恶性室性心律失常较常见）。将采用德国西门子公司生产的Vivid6型彩色多普勒超声诊断机对患者进行二维、M型以及多角度和多方位、多切面地对心肌结构层次实时地心脏观察。结果：11例患者超声心动图检查都证实均为左室受不同程度病变的累及,病变累及部位主要为：侧壁合并心尖部、侧壁中下段、心尖部、侧壁合并下壁,左房内径27-64mm,左室内径51-77mm,心肌厚度3.5-6.5mm。8例合并恶性室性心律失常,另有6例合并轻度二尖瓣反流,8例合并严重的三尖瓣反流现象。结论：彩色多普勒超声心动图具有在无症状的早期萌发阶段就可发现心肌结构异常功能无明显异常的特征性病变,那些病变原因模糊有待进一步研究的症状通常主诉为胸痛或早期心脏多普勒超声显示心脏增大的患者应采取紧急治疗措施,对那些致死性的恶性心律失常进行有针对性和预防性的干预,多能明显延长患者的生存时限和生存质量。

Objective：To study the heart tissue muscle densification is not complete heart color B ultrasonic clinical diagnosis and application value. Methods：From 2009 to 2011 in our myocardial dense not all 22 patients, patients’ clinical symptoms main show is dismayed, bosom frowsty （chest）, asthma, shortness of breath, paroxysmal dyspnea, muscle weakness, poor spirit. Among them, 4 cases had double lower limbs light to severe edema, after admission diagnosis of dilated cardiomyopathy （36 cases）, coronary heart disease in 10 cases, 6 cases pending investigation, these patients will appear different types of arrhythmia heart diagram change （malignant ventricular arrhythmia is relatively common）. Will use the German Siemens company produces the Vivid6 type color doppler ultrasonic diagnostic machine for patients with two-dimensional, M type and multi-angle and multi-dimensional and section of the real-time heart observation. Results：22 patients echocardiography were confirmed that are left ventricular by different lesions involving the, lesions involving the parts mainly：sidewall merger apex department, side lower part, apex department, sidewall merge inferior wall, left atrial inside 27-64 mm, left interior diameter 51 to 77 mm, myocardial thickness 3.5-6.5 mm. 8 cases merge malignant ventricular arrhythmia, another 6 cases merge light mitral valve reverse flow, 8 cases with severe tricuspid reverse flow. Conclusion：Color doppler echocardiography has no symptoms in the early stage of germination can detect cardiac structure abnormal function have no obvious abnormity characteristic lesions, the reason is not clear symptoms mainly for myocardial pain or heart increase patients early color doppler ultrasonic heart take corresponding treatment measures to prevent lethality arrhythmia and embolism and prolong survival in patients with time limit and quality of life.
