Stacy Warner is a fictional recurring character portrayed by Sela Ward on the medical drama House.

She was in a relationship with Dr. Gregory House (Hugh Laurie), when a clotted aneurysm in his right thigh led to an infarction during a game of golf, causing his quadriceps muscle to become necrotic.

She authorized a safer surgical middle-ground procedure by removing just the dead muscle, leaving House with a lesser, but serious, level of pain for the rest of his life.

The two meet again, five years later, at the end of season one; Stacy wants House to treat her husband, Mark (Currie Graham).

When the writers of the show wrote "Three Stories", the first episode in which Stacy appeared, the first name they came up with to play the character was Sela Ward.

[1] He was admitted at the Princeton-Plainsboro Teaching Hospital, but went misdiagnosed for three days due to doctors' concerns that he was exhibiting drug-seeking behavior (House eventually diagnosed the infarction himself).

[1] House had the dead muscle bypassed in order to restore circulation to the remainder of his leg, risking organ failure and cardiac arrest.

[1] After he was put into a chemically induced coma to sleep through the worst of the pain, Stacy, his medical proxy at the time, acted against his wishes and authorized a safer surgical middle-ground procedure between amputation and a bypass by removing just the dead muscle.

"[18] Shore explained that he wanted Ward for the part because she was the first person the writing staff suggested,[12][19] adding that she acts in a "simple" and "convincing way.

[5] In a 2005 Entertainment Weekly interview, Ward, who had never appeared in a medical show before,[12] stated that when she was young, her mother was sick for over nine years and she spent a lot of time in hospitals.

[22] On working with Ward, Laurie commented: "we're professionals who were lucky enough to be extremely well-equipped with a very sound, true script, the fact that Sela is immensely attractive and we got on well certainly is not an impediment.

[2] David Bianculli of The New York Daily News stated that with the addition of Stacy, House shifted "to the top echelon of today's TV dramas".
