Information about Port Access Surgery

I was researching new procedures for valve replacement surgery (Aaron will need a new valve for his pulmonary stenosis). I found some information about a new procedure called Port Access Surgery. Although since it is relatively new it does not fix the pulmonary valve (only aortic or mitral) it is interesting because it does not require traditional open heart surgery to do the replacement. I am hoping that when Aaron has to have surgery the pulmonary valve will also be available. The surgery is similar to what you would have done in the cath lab (minimally invasive). Here are some links:
