Conventional pediatric echocardiography is crucial for diagnosing congenital heart disease (CHD), but the technique is impaired by angle dependency. Vector flow imaging (VFI) is an angle-independent noninvasive ultrasound alternative for blood flow assessment and can assess complex flow patterns not visible on conventional Doppler ultrasound. 12 healthy newborns and 3 infants with CHD were examined with transthoracic cardiac VFI using a conventional ultrasound scanner and a linear array. VFI examinations revealed common cardiac flow patterns among the healthy newborns, and flow changes among the infants with CHD not previously reported with conventional echocardiography. For assessment of cardiac flow in the normal and diseased pediatric heart, VFI may provide additional information compared to conventional echocardiography and become a useful diagnostic tool.
传统儿科超声心动图对于诊断先天性心脏病（CHD）至关重要，但该技术受角度依赖性影响。矢量血流成像（VFI）是一种与角度无关的无创超声技术，用于血流评估，能够评估传统多普勒超声无法显示的复杂血流模式。使用传统超声扫描仪和线性阵列对12名健康新生儿和3名患有CHD的婴儿进行经胸心脏VFI检查。VFI检查揭示了健康新生儿常见的心脏血流模式，以及患有CHD的婴儿中血流变化，这些变化是传统超声心动图以前未报告过的。对于评估正常和患病小儿心脏的血流，与传统超声心动图相比，VFI可能提供额外信息，并成为一种有用的诊断工具。
