Critical pulmonary stenosis (PS) and pulmonary atresia with intact ventricular septum (PAIVS) require urgent neonatal intervention. Since PS may be more insidious than PAIVS during gestation, we hypothesized that neonates with PS would have lower rates of prenatal detection than PAIVS.

瓣膜肺动脉狭窄的产前检测率低：我们缺少什么？

严重的肺动脉狭窄（PS）和具有完整心室间隔的肺动脉闭锁（PAIVS）需要紧急的新生儿干预。由于在妊娠期PS可能比PAIVS更具隐蔽性，因此我们假设患有PS的新生儿的产前检测率要低于PAIVS。
