How would they sew it into place? I have never heard of this! How wonderful things are getting less, anything for less time in the hospital.
Here is an exerpt of an article on the procedure:
The Cribier-Edwards Percutaneous valve (Edwards Lifesciences, Irvine, Cal, USA) is a bioprosthesis made of three leaflets of equine pericardium sutured to a balloon expandable stainless steel stent. After balloon predilatation of the native valve, this bioprosthesis is crimped over a balloon catheter, and advanced over a stiff guidewire through the vessels (either from the femoral vein -antegrade/transseptal approach- or the femoral artery -retrograde approach-) up to the diseased fibro-calcific native aortic valve, using regular cardiac catheterization techniques. The bioprosthesis is then released by balloon inflation at mid-part of the native valve. In our institution, the technique is performed under local anesthesia and light sedation.

And here is another one from CC:
Percutaneous Mitral, Aortic and Pulmonic Valvotomy for Stenosis
Percutaneous valvotomy (also called valvuloplasty) is performed in many patients to treat mitral valve and pulmonic valve stenosis (narrowing of the valve). Percutaneous valvotomy may also be performed in carefully selected patients to treat stenosis of the aortic valve.
Mitral valvotomy
During mitral valvotomy, a catheter is placed through the femoral vein (in the groin) and guided into the chambers of the heart. The cardiologist then creates a tiny hole in the wall between the heart?s two upper chambers. This hole provides an opening for the cardiologist to access the left atrium with a special catheter that has a balloon at the tip.
The catheter is positioned so the balloon tip is directly inside the narrowed mitral valve. The valve opening is widened (or dilated) by rapidly inflating and deflating the balloon. Once the cardiologist has determined that the opening has been widened sufficiently, the balloon is deflated and removed.
The procedure is similar when performed in the aortic and pulmonic valves.
