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.
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.
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.

If I'm having a heart valve replacement do I have the right to insist on a tissue valve or mechanical valve?

Absolutely. Your doctor hopefully will apprise you of the risks/benefits of both valve types. You as the patient, armed with that advise, can make the decision. Often times, your doctor will recommend one over the other, but again, you make the final decision.
Sort of. You can discuss the 2 types of valves with your surgeon and even tell them what your preference is. If the surgeon disagrees you can see a different surgeon for a different opinion. It is possible you would find someone who would put the other type in. You cannot however demand a surgeon do a particular procedure or use a particular device if they don't think it is indicated.
