Balloon aortic dilatation is now a recognized therapy for aortic stenosis in children. Using retrograde approaches with either single or double balloons, successful dilatation can be readily achieved, but with little control of balloon position across the valve. We describe a femoral vein-femoral artery loop technique via a transseptal approach which facilitates antegrade crossing of the stenotic aortic valve and allows optimal balloon control and simultaneous pressure gradient recording during the procedure.
球囊主动脉扩张术现已成为治疗儿童主动脉狭窄的一种公认疗法。采用单球囊或双球囊逆行方法，可轻易实现成功扩张，但对球囊在瓣膜上的位置控制不佳。我们描述了一种经房间隔途径的股静脉-股动脉环技术，该技术有助于狭窄主动脉瓣的顺行穿过，并在手术过程中实现最佳球囊控制和同步压力梯度记录。
