It depends. I would suggest that you first speak with your cardiologist. If he or she clears you for surgery then schedule a consultation with a board certified plastic surgeon to discuss liposuction. Also, if you are the right candidate, you may want to consider liposuction under local anesthesia. Hope this helps.
Every case is different. It would depend entirely on the specifics. Obviously, a clearance from your neurologist/cardiologist would be needed. Because it is not uniformly contraindicated, you should seek consultation/evaluation to find out.
