I was told similar statistics regarding afib and even pacemaker implants after aortic valve surgery. I, too, was told that the main nerve bundle that carries the electrical impulses to the chambers of the heart was very close to the aortic valve, and that sometimes in order to remove a badly calcified valve these nerves are disrupted or damaged. The resulting rhythm disturbances can be either temporary or permanent. In my case, in the few days immediately following valve replacement, I had everything you could think of -- afib, a-flutter, bradycardia, tachycardia and, most frighteningly, long 15 to 20 second pauses between beats. Knowing all this, I readily agreed to the pacemaker implant. I think I'm getting used to it, and will just get on with living my life.
