"I want to share some important personal news with you," Charlie Rose tweeted Wednesday morning.

The news -- that the 75-year-old CBS This Morning anchor (and PBS talk show host) will undergo heart surgery on Thursday -- was also announced on the show by his co-anchors Norah O'Donnell and Gayle King.

Rose is scheduled to have the replacement aorta valve he'd previously received replaced again.

Here's Rose's full statement:

"Almost 15 years ago skilled surgeons replaced my aorta valve with a new replacement valve. It has served me well enabling me to live the vigorous, full, complete life you are all so familiar with. No one loves life more than I do.
— To continue to live this amazing life so full of challenges and friends, including so many of you in the audience, I have chosen to replace the valve with a new one.
