自身抗体相关性先天性心脏传导阻滞1例报告

摘要

ObjectiveTo explore the pathogenesis, clinical manifestations, diagnosis, and treatment of autoanti-body-associated congenital heart block.MethodsThe clinical data of one child with autoantibody-associated congenital heart block was retrospectively analyzed.ResultsIn 24 week gestation, fetal bradycardia had been found by routine fetal echocar-diography. After birth, the anti-SSA/Ro antibodies and anti-SSB/La antibodies were positive in both infant and her mother. The diagnosis of autoantibody-associated congenital heart block was conifrmed. Intravenous immunoglobulin at 1 g/kg was adminis-trated. At 6 months follow-up, the electrocardiogram suggested type I second degree atrioventricular block.ConclusionIn the fetus or neonates found to have bradycardia and excluded the cardiac structural abnormalities, the autoimmune antibody should been tested and early intervention should been promoted.%目的：探讨自身抗体相关性先天性心脏传导阻滞的发病机制，临床表现及诊断和治疗。方法回顾性分析1例自身抗体相关性先天性心脏传导阻滞患儿的临床资料。结果患儿于24周胎龄时即在超声检查中发现胎儿心动过缓，出生后检测患儿及其母亲的抗SSA/Ro抗体和抗SSB/La抗体均为阳性，确诊为自身抗体相关性先天性心脏传导阻滞，予静脉注射免疫球蛋白1 g/kg治疗。6月龄随访提示仍为Ⅱ度Ⅰ型房室传导阻滞。结论当发现胎儿或新生儿心动过缓且排除心脏结构异常时，应完善自身免疫抗体检查并尽早干预。
