On my first day, I saw three heart procedures. The first was a surgery dealing with a pacemaker and a defibrillator. During the procedure, Dr. Hamrick added a third lead to the pace maker. During this, I learned about improvements that are being made to pacemakers. Below is a picture of the beginning of nanotechnology being used for hearth surgery and pacemakers. The second and third procedures were both A TAVR. This was a value replacement via a catheter coming in from the femoral artery.
