Hi Darlia, Pacemakers are not incompatible with breast implants. As in all things, details matter. Pacemakers come in different varieties that are designed for different heart rhythm problems. There are basically two parts, the leads which attach to the heart itself and the generator which has the logic circuits and battery. We rarely need to address the leads.The generator often sits right where we place breast implants. This can cause two problems. The shape of the generator can alter the esthetic result of the augmentation. More importantly, electric energy (which we often use to control bleeding) can mess up the generator and effect the function of your heart. The first issue can be corrected by moving the generator to a different location, such as your lower abdomen. That has to be done with the assistance of your interventional cardiologist. All it takes is a longer lead extension and a little creativity. It is a hassle but if you need to replace the generator, a site re-position can be considered. If that's not too important to you, the augmentation can be performed with the generator in place. All generators have a default mode that can be turned on with a sterile magnet. As long as we prevent damaging the function of the pacemaker, it should not be a problem. It goes without saying that you need the approval of your cardiologist, not to agree with augmentation, but that you are a safe candidate for the surgery.
