Percutaneous balloon pulmonary valvuloplasty (PBPV) is the treatment of choice for isolated pulmonary valve stenosis. While this procedure is highly efficacious and has an excellent safety profile, as currently practiced, patients are obligatorily exposed to the secondary risks of ionizing radiation and contrast media. To mitigate these risks, we developed a protocol which utilized echo guidance for portions of the procedure which typically require fluoroscopy and/or angiography. Ten cases of echo-guided pulmonary valvuloplasty (EG-PBPV) for isolated pulmonary stenosis in children less than a year of age were compared to a historical cohort of nineteen standard cases using fluoroscopy/angiography alone, which demonstrated equivalent procedural outcomes and safety, while achieving a median reduction in radiation (total dose area product) and contrast load of 80% and 84%, respectively. Our early experience demonstrates that EG-PBPV in neonates and infants has results equivalent to standard valvuloplasty but with less radiation and contrast.

新生儿和婴儿联合超声和透视引导的肺动脉瓣成形术：疗效和安全性。

经皮球囊肺动脉瓣成形术（PBPV）是孤立性肺动脉瓣狭窄的首选治疗方法。尽管该程序非常有效并且具有出色的安全性，但正如目前所采用的那样，患者不得不暴露于电离辐射和造影剂的次要风险中。为了降低这些风险，我们开发了一种协议，该协议在通常需要透视和/或血管造影的部分程序中使用回波引导。将 10 例用于治疗 1 岁以下儿童的孤立性肺动脉瓣狭窄的回声引导肺瓣膜成形术 (EG-PBPV) 与仅使用透视/血管造影的 19 例标准病例的历史队列进行比较，证明了相同的手术结果和安全性，同时实现辐射（总剂量面积乘积）和造影剂负荷的中位减少，分别为 80% 和 84%。我们的早期经验表明，EG-PBPV 在新生儿和婴儿中的效果与标准瓣膜成形术相当，但辐射和造影剂更少。
