Cardiothorasic Surgery refers to surgeons who specialize in operations on the heart and blood vessels to prevent or repair damage caused by clogged arteries, heart attacks or birth defects.  One major problem that a patient can aquire from certain cardiothorasic procedures is called a sternal would infection, or mediastenitis.  This is a devistating infection that can cause death if not treated immediately.  This infection alone can cost a hospital several hundred thousand dollars to treat.  Applying platelet rich plasma to the sternal wound while closing can significantly reduce the incidence of aquiring mediastenitis.  Check out more information on PRP for Cardiothorasic here.
