Randy Travis had heart surgery yesterday after being admitted to a Dallas area hospital on Monday in critical condition, according to his sister in-law.

"We have been told he has had surgery," Teresa Traywick, the wife of Randy's brother Ricky Traywick, tells PEOPLE. "Our prayers are going out to him because my husband just had a heart attack last year, so it is in their family."

Randy is suffering from complications of recently acquired viral cardiomyopathy," a rep has said. Viral cardiomyopathy is a weakening of the heart muscles due to infection.

"Their mother passed away at an early age with her heart, so it is like these boys are following right in their footsteps," Teresa Traywick said. "My prayers are with them. That's all I can say right now."
