Breast augmentation may be possible for some patients with a pacemaker, but it should only be considered after careful cardiac clearance and surgical planning. The important details are why the pacemaker was placed, whether you depend on it continuously, where the device and leads sit on the chest, and whether the implant pocket or incision would be close to that area. Your plastic surgeon should coordinate with your cardiologist or electrophysiologist and the anesthesia team before surgery. You may need a recent pacemaker check, written clearance, and a specific plan for monitoring and electrocautery during the operation. If the pacemaker is positioned high on the chest, implant placement or incision choice may need to be adjusted, so an in-person exam and cardiology clearance are essential before moving forward.
