Aortic Stenosis Fixed With A Poke Of The Needle?

From my earlier post you will see that there have been several new advances reported this week in cardiology.  The biggest one by far is a study called TAVI or Transcatheter Aortic Valve Implantation.  This new study has reported some great results with implanting a brand new aortic valve through a simple needlestick during a heart catheterization.

As people get older, the aortic valve frequently becomes hard and narrowed.  This condition is called aortic stenosis.  Aortic stenosis is considered severe when the valve area is less than 1cm².  Greater than 4% of patients over age 85 have aortic stenosis but unfortunately they are considered a poor candidate for traditional open heart surgery to replace the valve by that age. A recent option for older patients has been balloon angioplasty of the valve by heart catheterization but this gives poor results and adds less than a year of optimal results.

The new TAVI study has shown that a prosthetic aortic valve can actually be placed safely over the old, hardened valve by a simple needlestick during heart catheterization.  The results of the study show significant improvement in valve function and much fewer deaths one year after the procedure.  To see a video of this type of procedure, check out the following link:
