先天性冠状动脉畸形的超声心动图诊断

目的探讨超声心动图诊断先天性冠状动脉畸形的意义。方法对本院诊治的40例先天性冠状动脉畸形的超声心动图结果与心血管造影、手术结果进行分析比较。结果冠状动脉起源于肺动脉12例占30%;冠状动脉起源于主动脉窦8例占20%;冠状动脉瘘20例占50%,累及右冠状动脉12例(60%)。其中多个瘘口1例,累及左冠状动脉8例(占40%)。瘘入右心腔13例(占65%),瘘入肺动脉5例(占25%),瘘入左心腔2例(占10%)。超声心动图敏感性92%,特异性100%。对冠状动脉起源于肺动脉1例误诊为心内膜弹力纤维增生症,1例左冠状动脉起源于右冠窦漏诊。结论超声心动图对先天性冠状动脉畸形有较高的诊断价值。可作为首选诊断方法。对先天性患儿应仔细探测左右冠状动脉及分支,并结合其它临床资料进行分析。
