The nurse just came with an update, and so far so good. Everything is going according to plan. She estimated that they are about half-way done. The surgeon is currently patching the tunnel with a piece of Preston's pericardium. We are waiting to hear about the location of the right coronary artery and whether it will need to be re-implanted as well as the function of the mitral and aortic valves and whether they need some kind of repair. Keep those prayers coming. They mean the world to us.
