摘要

Catheter-based aortic valve implantation is a rapidly evolving technique with potential to create a paradigm shift. With every new therapeutic modality we face new questions and problems that need to be addressed. Identification of the precise location and size of the aortic valve annulus and placement of the stent-valve complex to the desired location are some of the challenges confronted by the operators. The Edwards-Sapien aortic valve prosthesis is sewn in a metal stent frame that is 16-mm tall. It should be placed in the aortic valve annulus so that stent extends from the left ventricle outflow tract above the mitral valve insertion point to the aortic root covering the calcific leaflets of the native aortic valve, but remaining below the coronary ostia. The placement is done with a single, irreversible balloon inflation, which makes the precision of placement paramount.
