"I spoke to Aaron's father, Bob, and he indicated that things went well," general manager Ed Wade said in a statement released by the Astros. "Certainly, our prayers are with Aaron and the entire Boone family in hopes of a full recovery."
Another update: http://www.chron.com/disp/story.mpl/sports/6347569.html Give credit to the Astros medical staff for picking up on this before it was too late. VIERA, Fla. – Astros shortstop Aaron Boone is out of intensive care and resting comfortably following open heart surgery performed Thursday at Stanford Medical Center in Palo Alto, Calif. Bob Boone, the father of the former All-Star and the assistant general manager and vice president of the Washington Nationals, provided Astros manager Cecil Cooper with an update on his son’s condition prior to the Astros-Nationals game today. “It was a little more serious that we kind of expected,” he said. “The surgeon told us it’s good we did it now.” "They rebuilt his valve, which they were hoping to do,” Bob Boone said. “The other scenario was putting a mechanical valve in there. They don’t have any data on that. He may have to do that years from now.” Aaron Boone is expected to be released from the hospital Tuesday or Wednesday, and Bob Boone said the surgeon wants him to double his activity every week. "I think he’s got an outside chance of being back (in the majors),” Bob Boone said. “He really hasn’t thought about that. He said, ‘Let me live first.’”
