Difficult to treat recurrent stenosis of the aorta

The risk associated with repeated treatment of aortic stenosis is as high as 5% and increases to as much as 25% in complex heart diseases. Among the methods that are commonly accepted and used in the treatment of recurrent aortic stenosis are balloon dilatation and stent implantation. In this study we describe five patients with recurrent stenosis of the aorta treated with stent implantation. The short-term results of such treatment are promising. However, in some cases it is only palliative in character and does not completely resolve the problems arising from congenital heart disease. (Cardiol J 2007; 14: 186-192)
