8例小儿心肌炎进行了心导管检查与右室心内膜心肌活检,活检标本组织学变化的程度与临床表现的严重程度呈良好相关,遗留心脏机能损害的患者活检结果与临床过程符合。心肌炎占婴幼儿获得性心脏病的大部分,心肌活检已报告应用于心肌炎的诊断。 8例心肌炎患者的临床表现归纳于(表一)。
Cardiac catheterization and right ventricular endocardial biopsy were performed in 8 pediatric myocarditis. The extent of histological changes in the biopsy specimens correlated well with the severity of clinical manifestations. The biopsy results in patients with impaired cardiac function were consistent with clinical course. Myocarditis accounts for most of infantile acquired heart disease and myocardial biopsy has been reported for the diagnosis of myocarditis. The clinical manifestations of 8 patients with myocarditis were summarized (Table 1).
