Poison singer and reality-TV star Bret Michaels had successful surgery on Monday to repair a hole in his heart.

It was some good medical news after several years of health scares for the 47-year-old [article id="1639835"]"Celebrity Apprentice" winner[/article]. According to the Associated Press, the surgery took place at St. Joseph's Hospital and Medical Center in Phoenix, and a hospital spokeswoman said Michaels is recuperating and remains in the facility's intensive care unit for observation.

Doctors discovered a [article id="1639913"]hole in Michaels' heart[/article] in April 2010 after he was treated for a [article id="1637737"]brain hemorrhage[/article]. During Monday's procedure, doctors inserted a catheter into a vein in Michaels' groin with a surgical device and then used tiny cameras to aid them in implanting a closure device. The device will stay inside the rocker permanently to stop abnormal blood flow between two chambers of his heart, which doctors think could have caused his hemorrhage last year.

The impending surgery didn't slow Michaels down over the weekend, when he attended a classic car show in Phoenix and auctioned off his 1969 Camaro -- which had a cameo in his recent VH1 series, [article id="1650145"]"Bret Michaels: Life as I Know It"[/article] -- for more than $200,000, before checking into the hospital on Saturday night to prepare for the procedure.

"Barring any complications, I should be out within three or four days," he told

Michaels, who also had an emergency appendectomy in April, recently [article id="1654798"]proposed to his girlfriend[/article] of 16 years, Kristi Gibson, who is also the mother of his two children.
