(CNN) - Former first lady Barbara Bush was moved Saturday out of intensive care after undergoing heart surgery earlier this week, the former president's spokeswoman said.
Jean Becker, a spokeswoman for former President George H.W. Bush, said the former first lady would be in the hospital for about another week.
Doctors at Methodist DeBakey Heart & Vascular Center in Houston, Texas, performed a 2 1/2-hour surgery on Barbara Bush on Wednesday, and replaced her aortic valve with a pig valve.
"From our perspective, this was a very routine procedure, and we expect her to make an excellent recovery," Dr. Gerald Lawrie told reporters on Thursday.
Bush had experienced "severe narrowing of the main valve that lets the blood come out of the heart into the circulation," Lawrie said.
He said an echocardiogram showed her condition was "extremely severe." Typical symptoms of problems with an aortic valve include shortness of breath,
fatigue, weakness and swelling, he said.
Though his patient is 83, "she's a very fit lady," which helped make the operation a "relatively straightforward" procedure," he said.
Barbara Bush had been diagnosed with the problem less than a week before the surgery. Becker said the former president was visiting his wife Saturday at
Barbara Bush has forbidden her children, which include former President George W. Bush and former Florida Gov. Jeb Bush, from visiting until she leaves
the hospital, Becker said.
George H.W. Bush visited her shortly after the operation, saying "I've been a nervous wreck about it."
The former politician said he had received telephone calls of support from President Barack Obama and from surviving former presidents.
Asked to describe what occurred between the two when he saw her, he said, "I don't remember any words. I'm not the anecdotal one in the family. It was
just a reunion of two people who love each other."
Afterward, the former president turned to a hospital administrator and said, "I'm sorry I get emotional, but I can't help it."
