pubmed-article:2953320 | pubmed:abstractText | 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. | lld:pubmed |
