UPDATE: The Associated Press reports that Randy Travis remains in critical condition following surgery. Earlier today, Travis' publicist told ET: "As a complication of his congestive heart failure, Mr. Randy Travis has suffered a stroke and is currently undergoing surgery to relieve pressure on his brain."

The doctors treating critically ill Randy Travis spoke out for the first time Wednesday about the country star's condition and revealed that he was in congestive heart failure due to a viral respiratory illness that put him in the hospital on Sunday.



Travis remains in critical condition in a Dallas, TX hospital. Earlier, Drs. William Gray and Michael Mack of the Baylor Health Care System released a video, saying, "[Travis'] condition has stabilized and he has shown signs of improvement" while being treated for viral cardiomyopathy.

A statement released Tuesday by the singer's publicity company also revealed that Travis had undergone placement of an IMPELLA peripheral left ventricular assist device to help improve his circulatory function.

The 54-year-old Grammy winning singer was admitted to a hospital in Dallas on Sunday, with his rep saying he suffered complications from a "recently acquired viral cardiomyopathy." The condition leads to a weakening and enlarging of the heart muscle, making it more difficult for the heart to pump blood to the rest of the body.



The music legend -- who had been scheduled to perform at a canceled show Wednesday at the Deadwood Mountain Grand Casino in Deadwood, SD -- is known for hits such as Three Wooden Crosses, I Told You So, Deeper Than the Holler and Forever and Ever, Amen.
