摘要

作者对3例年龄分别为10个月、15岁和16岁的主动脉瓣狭窄患者行球囊瓣膜成形术(BVP)治疗的经验进行了讨论。所有患者均在暴露右侧肩胛下动脉的情况下行BVP。左心室(LV)收缩压BVP之前198 + / - 45毫米汞柱平均收缩压梯度LV和主动脉后102 - 32毫米汞柱。BVP收缩压在LV减少26.5%和146 + / - 27.8毫米汞柱,LV和主动脉之间的收缩压力梯度降低64.8%和36.0 + / - 7.5毫米汞柱。没有增加血液返流的对比证明了通过阀进入LV重复造影术。未见与BVP相关的并发症。因此,BVP可能是先天性AVS手术的替代方案。这种方法明显适用于早期AVS患者,可以避免体外循环手术。作者认为,当主动脉瓣环直径小于20mm时,BVP是老年先天性AVS患者的有利选择。

[Balloon valvuloplasty in congenital aortic stenosis].

The authors discuss their experience with balloon valvuloplasty (BVP) in aortic valvular stenosis (AVS) in 3 patients aged 10 months, 15 and 16 years. BVP was carried out in all of them with exposure of the right subscapular artery. Left ventricular (LV) systolic pressure before BVP was 198 +/- 45 mm Hg on the average, systolic pressure gradient between the LV and the aorta was 102-32 mm Hg. After BVP systolic pressure in the LV reduced by 26.5% and was 146 +/- 27.8 mm Hg, the systolic pressure gradient between the LV and the aorta reduced by 64.8% and was 36.0 +/- 7.5 mm Hg. No increased regurgitation of contrasted blood through the valve into the LV was demonstrated by repeated aortography. Complications connected with BVP were not encountered. Thus, BVP may be an alternative to surgery in congenital AVS. This method is evidently indicated for patients of early age with AVS, which allows operations with extracorporeal circulation to be avoided. According to the authors, BVP is expedient in congenital AVS in older patients when the diameter of the aortic valvular ring is less than 20 mm.
