The purpose of this study was to assess 4 Fr Judkins catheters with modified shorter tips for performing selective coronary angiography in infants and young children. Twenty patients ranging 6 weeks to 3. 8 years of age were enrolled. Retrograde left heart catheterization and selective coronary angiography were performed. Right (JR) and left (JL) catheters with modified 1.5- and 2.5-cm curves (Cordis) were used. Thirty-six of 37 coronary arteries were successfully cannulated and demonstrated. Median procedure time was 95 sec for the right and 50 sec for the left coronary artery. Median fluoroscopy time was 1.1 min for the right and 0.7 min for the left coronary artery. The JL 1.5 appeared best suited for patients less than 75 cm tall. The JR 1.5 was suitable for patients up to 85 cm tall. Taller patients required the 2.5-cm curves. It is concluded that these modified 4 Fr Judkins catheters were effective.

:本研究的目的是评估4个Fr Judkins导管,这些导管具有改良的较短尖端,用于在婴幼儿中进行选择性冠状动脉造影。招募了20名6周至3. 8岁的患者。进行逆行左心导管检查和选择性冠状动脉造影。使用具有改良的1.5厘米和2.5厘米曲线的右(JR)和左(JL)导管(Cordis)。 37例冠状动脉中有36例成功插管并显示。右侧冠状动脉的中位手术时间为95秒,左侧冠状动脉的中位手术时间为50秒。透视的中位时间,右侧冠状动脉为1.1分钟,左侧冠状动脉为0.7分钟。 JL 1.5似乎最适合身高不到75厘米的患者。 JR 1.5适用于身高不超过85厘米的患者。较高的患者需要2.5厘米的曲线。结论是这些改良的4 Fr Judkins导管是有效的。
