患者,男,23岁。因心悸、气短、胸闷,外院可疑心肌炎来院就诊。超声所见:左室长轴不能显示标准的常规切面,肝脏位于腹腔右侧,心房正位,心室左绊,房室结构异常。大动脉短轴切面观,正常的右室流出道包绕主动脉根部形态消失,肺动脉与主动脉正常的左前右后关系消失,而呈现两个动脉短轴切面,主动脉位于肺动脉的左前方,呈弧形向后延伸,肺动脉则左右后与主动脉平行向上后伸延,并能显示肺动脉分叉,肺动脉及左右分支发育正常,四腔心切面显示,肺静脉仍与左房相通,但左室变为解剖学右室(功能性左室),右室变为解剖学左室(功能性右室),并在解剖性右室即功能性左室靠心尖部见到一回声增强的调节束,该侧房室瓣的附着点亦较对侧为低,其流出道与主动脉相通,而解剖学左室即功能性右室其流出道与肺动脉相通,但两组半月瓣正常,房室间隔连续完整。超声诊断:完全性矫正型大动脉转位。
Patient, male, 23 years old. Due to heart palpitations, shortness of breath, chest tightness, hospital suspected myocarditis to hospital. Ultrasound findings: the left ventricular long axis can not show the standard conventional section, the liver is located in the right side of the abdominal cavity, atrial anterior position, left ventricular stumbling, abnormal atrioventricular structure. The view of the short axis view of the aorta showed that the normal right ventricular outflow tract disappeared around the aorta and the normal left anterior and posterior right pulmonary artery and aorta disappeared, presenting two arterial short axis views. The aorta was located in the left front of the pulmonary artery. The arc extends backward, the left and right pulmonary arteries extend parallel to the aorta, and the pulmonary arteries can be bifurcated. The pulmonary arteries and the left and right branches develop normally. The four-chamber coronal section shows that the pulmonary veins still communicate with the left atrium but the left ventricle becomes Anatomy of the right ventricle (functional left ventricle), right ventricle into the anatomy of the left ventricle (functional right ventricle), and in the anatomy of the right ventricle, ie, functional left ventricular apex, an echogenic regulation bundle Lateral atrioventricular valve attachment point is also lower than the contralateral, the outflow tract and the aorta, and anatomy of the left ventricle that is, the right ventricular outflow tract and pulmonary artery, but the two groups of semilunar valve normal, atrioventricular septal continuous complete. Ultrasound diagnosis: complete correction of transposition of the great arteries.
