Former U.S. President George W. Bush underwent successful surgery at a Dallas hospital on Tuesday to place a stent in a blocked heart artery, a spokesman said.

Bush, 67, was "in high spirits, eager to return home tomorrow and resume his normal schedule on Thursday," spokesman Freddy Ford said in a statement.

Doctors discovered the blockage on Monday during Bush's annual physical exam at the Cooper Clinic in Dallas, the statement said. Doctors recommended a stent to open the blockage and he underwent surgery on Tuesday morning at Texas Health Presbyterian Hospital, the statement said.
