Aortic valvuloplasty has recently been introduced in the treatment of some cases of aortic stenosis. In the case reported here, the aortic orifice was so difficult to traverse by the retrograde route that the obstacle was approached by trans-septal catheterization. The aortic area, initially estimated at 0.25 cm2, increased to 0.82 cm2 at the end of the examination. However, additional dilatation by the retrograde route was necessary, using a catheter 25 mm in diameter.
主动脉瓣成形术最近已被应用于某些主动脉狭窄病例的治疗。在本文报道的病例中，经逆行途径很难穿过主动脉口，因此通过经房间隔导管插入术来处理这一障碍。最初估计主动脉瓣口面积为0.25平方厘米，检查结束时增加到了0.82平方厘米。然而，仍需要使用直径25毫米的导管经逆行途径进行额外的扩张。
