Experience with stepwise balloon dilatation of congenital aortic valve stenosis using the new Inoue balloon catheter in 16 patients (aged 12 +/- 4.6 years; group II) is presented. Results are compared with those obtained in 15 patients (10 +/- 6 years; group I) in whom standard balloon catheters were used. The procedure resulted in a similar transvalvar gradient reduction in both groups (83 +/- 25 to 34 +/- 14 mmHg in group I versus 84 +/- 21 to 28 +/- 10 mmHg in group II). Significant aortic incompetence occurred in three patients from group I and in four from group II. There was no difference in the average increase in AR grade between the groups. At follow-up (group I, 24 +/- 13 months; group II, 7 +/- 3 months) there was no significant change in transaortic gradient or aortic incompetence. Balloon aortic valvuloplasty for congenital aortic stenosis carries a risk of aortic incompetence. Stepwise dilatation of the stenosis does not prevent this complication. The Inoue balloon catheter offers technical advantages.
本文介绍了使用新型井上球囊导管对16例先天性主动脉瓣狭窄患者（年龄12±4.6岁；第二组）进行逐步球囊扩张的经验。将结果与15例使用标准球囊导管的患者（年龄10±6岁；第一组）的结果进行比较。两组患者术后跨瓣压差均有相似程度的降低（第一组从83±25 mmHg降至34±14 mmHg，第二组从84±21 mmHg降至28±10 mmHg）。第一组有3例患者出现明显主动脉瓣反流，第二组有4例。两组间主动脉瓣反流分级的平均增加无差异。随访时（第一组24±13个月；第二组7±3个月），跨主动脉压差或主动脉瓣反流无显著变化。先天性主动脉瓣狭窄的球囊主动脉瓣成形术有发生主动脉瓣反流的风险。逐步扩张狭窄并不能预防这一并发症。井上球囊导管具有技术优势。
