主动脉——左心室通道(ALVT)是一罕见的畸形.此通道起源于右冠状窦至右冠状窦口左侧这一区域,穿过右室流出道和室间隔于主动脉瓣下进入左室。各国文献报道本病尚不足40例,而亚洲国家未见1例报道.作者们报道1例经超声心动图和心血管造影确诊,并通过手术治疗成功的 ALVT患儿。患儿系足月顺产的男婴,出生体重3.9kg,生后不久即出现呼吸急促,3周后发生心力衰竭,给予药物治疗.4(1/2)月龄时来院就诊,查体心率增快,心前区间闻及3/6级连续性杂音。肝脏于右肋缘下3cm处触及,股动脉搏动减弱。心电图示左室肥大,1/6号联ST段降低.X线胸部平片示心脏扩张伴升主动脉瘤。二维超声心动图胸骨旁左室长轴切面示室间隔回声失落,可见通道壁从室间隔最
The aorta-left ventricular pathway (ALVT) is a rare deformity that originates from the right coronary sinus to the area to the left of the right coronary ostium, through the right ventricular outflow tract and into the left ventricular compartment below the aortic valve . The literature reported that the disease is less than 40 cases, while the Asian countries have not seen a report of the authors of a report by echocardiography and cardiovascular angiography confirmed, and the success of surgical treatment of ALVT children. Children born in term full-term infants, birth weight 3.9kg, shortly after birth, shortness of breath, heart failure occurred after 3 weeks, given drug therapy .4 (1/2) months of age to hospital, physical examination heart rate Fast, precordial range and 3/6 continuous noise. The liver touches at 3 cm below the right costal margin and the femoral pulse weakens. ECG left ventricular hypertrophy, ST segment 1/6 decreased .X-ray showed plain chest expansion with ascending aortic aneurysm. Two-dimensional echocardiography chest next to the long axis of the left ventricle showed loss of echogenic septal echo, showing the channel wall from the most septal
