Abnormal EKG. Is it possible to have a facelift?

Thank you for your question.  The safety of having a facelift with your diagnosis is a question that should be directed to your cardiologist.  Consult with your doctor about your condition then discuss further with a plastic surgeon.

This is really most appropriately evaluated by a cardiologist or in a preoperative evaluation by an anesthesiologist, who can then decide if further cardiology workup is indicated.

You would need an evaluation by a cardiologist to determine your risk for surgery with your valve dysfunction.  You plastic surgeon should have a discussion with the cardiologist to make the final determination to proceed with surgery.
