Any risks with tissue or metal heart valve replacements in a person who has sle?

Possibly: Need to discuss individual case with cardiologist and cqrdiothoracic surgeon if there is heart involvement, and if drugs would make surgery or recovery more difficult.

Same as non lupus : The risks are the same as people who do not have lupus but there can be issues related to the activity of the lupus, the medication such a steroid or immunosuppression and risk of infection. Just because you may have lupus does not mean that you will not have a good surgical outcome. Remember you are a normal person who also has lupus.

Yes: Systemic lupus erythematosus (sle or lupus) complicates heart surgery in general. Underlying organ dysfunction, immunosuppression increasing risk of infection, and altering already abnormal immune and coagulation systems with cardiopulmonary bypass increase surgical risk. There is no real consensus on what kind of valve in better for patients with lupus, and good data are lacking.
