Country singer Randy Travis, 54, remains hospitalized with a heart condition, according to his sister-in-law Teresa Traywick.

"We have been told he has had surgery. Our prayers are going out to him because my husband just had a heart attack last year, so it is in their family," she says in a statement on People.com. "Their mother passed away at an early age with her heart, so it is like these boys are following right in their footsteps. My prayers are with them. That's all I can say right now."

Travis was in critical condition at a Texas hospital after being admitted Sunday. According to a press release from his publicist, the singer of such hits as Forever and Ever, Amen, On the Other Hand and Three Wooden Crosses is suffering complications of recently acquired viral cardiomyopathy.

Viral cardiomyopathy is a weakening of the heart muscles caused by a viral infection.

Travis, who pleaded guilty to a charge of driving while intoxicated in Texas earlier this year, was hospitalized in 2012 after a fight near a church in Plano, Texas.

Meanwhile, celebrities are sending their thoughts to Travis on Twitter.

Keith Urban: "Sending healing strength and love to you this morning @randytravis -KU"

Tracy Lawrence: "Sending a get well message out to my buddy @randytravis tonight. Thinking of you and wishing you a speedy recovery."

Lance Armstrong: "Thoughts go out to @randytravis. Heal up soon my man! One of country music's greatest voices ever."
