Country music veteran Randy Travis remains in critical condition after undergoing a procedure to stabilise his heart.

The singer, 54, was hospitalised in Texas on Sunday (07Jul13) after suffering complications relating to a recently-diagnosed viral cardiomyopathy, a heart condition caused by an infection.

He had a special pump fitted to help improve his blood flow before transferring medical centres, but his health remains a serious concern for doctors who are now treating him in Dallas, according to his publicist Kirt Webster.

The representative has also expressed his gratitude for the outpouring of love from devotees in light of Travis' health crisis, stating, "We are very thankful to the fans for their love and support during this time."

A planned concert in Deadwood, South Dakota on Wednesday (10Jul13) has been cancelled as a result of the star's hospitalisation.
