Los Angeles Lakers second-round draft pick Ronny Turiaf underwent heart surgery Tuesday and was expected to make a full recovery, the team said.

The former Gonzaga star had surgery to repair an enlarged aortic root and preserve his aortic valve. He's expected to be hospitalized about a week.

The six-hour operation was performed by Dr. Craig Miller at the Stanford University Medical Center.

Turiaf, selected 37th overall in the draft, was diagnosed with an enlarged aortic root during a team physical after the draft. Had the condition not been caught and treated it could have been fatal, team spokesman John Black said.
