If I Have A-Fib, How Dangerous is Panniculectomy?

I had a complete hysterectomy 13 years ago which almost immediately caused skin to lap over the scar area. I have lost weight in recent years and now and getting infections under the "apron of skin" and it's extremely uncomfortable. I know that insurance doesn't pay for tummy tucks and I am more interested in getting rid of the excess skin and thus stopping the miserable infections. I was diagnosed with A-Fib last year and have it under controll with medication. what is the risk?
