彩色多普勒超声心动图在292例小儿心脏杂音检查中的应用

Application of color Doppler echocardiography for appraisement of 292 cases of pediatric heart murmur

[背景]评价彩色多普勒超声心动图在小儿心脏杂音检查中的应用价值.[病例报告]对292例因心脏杂音而就诊的0-15岁儿童进行常规切面、剑下及胸骨上窝切面彩色多普勒超声心动图检查,复杂畸形者按心脏三级顺序分段法检查并作出诊断;检出221例（75.7%）心脏病患儿,其中以室间隔缺损、房间隔缺损、动脉导管未闭及法洛氏四联症为多见;年龄越大,先天性心脏病检出率越低.[讨论]因2级以上杂音而就诊的儿童有必要接受彩色多普勒超声心动图检查,彩色多普勒超声心动图可作为早期诊断小儿先天性心脏病的首选检查手段.

BACKGROUND To study the value of color Doppler echocardiography for appraisement oi pediatric heart murmurs. CASE REPORTS 292 children from newborns to fifteen years old who had heart murmurs and were examined with color Doppler echocardiography through routine views, subcostal and suprasternal views. The complex malformations were detected and diagnosed with the method of three grades disjunction. Total 221 （75.7 % ） congenital heart diseases were found out, including the ventricular septal defect （VSD）, atrial septal defect （ASD）, patent ductus arteriosus（PDA） and tetralogy of fallot （TOF） seen in the most common diseases, and lower heart abnormality rate in the elderly child. DISCUSSION The color Dopplel echocardiography plays a most important role in children who had upon grade 2 heart murmurs, also couldn＇ ignore neonatal grade 2 heart murmurs. The color Doppler echocardiography is a convenient, noninvasive and common method. It is a primal method for early diagnosis and guidance of treatment on congenital heart diseases, in childhood.
