A modified technique for pulmonary valvuloplasty is described in a 1-day-old newborn with near pulmonary atresia. A transumbilical venous approach and a complete set of devices for coronary angioplasty were utilized; the principal technical innovation was the use of a 7 French right coronary artery guiding catheter. This allowed a firm support to advance the first balloon catheter (a 3.5 coronary angioplasty catheter) through the pulmonary valve, maintaining the guidewire in a stable position in the descending aorta. The dilation was easily completed with progressively larger balloons. The total procedure time was 82' (fluroscopy time 20'), significantly shorter than the previous personal experience and the data from the literature.
本文描述了一种用于1日龄、近肺动脉闭锁新生儿的改良肺动脉瓣成形术技术。采用经脐静脉途径及一套完整的冠状动脉血管成形术器械；主要技术创新是使用了一根7F右冠状动脉引导导管。这使得在将第一根球囊导管（一根3.5冠状动脉血管成形术导管）推进通过肺动脉瓣时能获得稳固支撑，同时将导丝稳定在降主动脉内。使用逐渐增大的球囊轻松完成了扩张。总手术时间为82分钟（透视时间20分钟），明显短于之前个人经验及文献数据。
