Bret Michaels Doing Well Following Heart SurgeryBret Michaels' heart has done a lot of lovin' in the rocker's 47 years, and now it's time for a little TLC.

Doctors found a hole in Michaels' heart last May while the Poison rocker was hospitalized following a mini-stroke. The surgery to repair the hole was performed on Monday at Phoenix's St. Joseph's Hospital, near Michaels' Scottsdale, Ariz., home.

Just last month, Michaels voiced his optimism about the procedure, the prepraration for which was already underway. "I'd say if everything goes well, I'll spend about three days in the hospital," he told PEOPLE. "And then about three weeks after that just really, really, really taking it easy."

A rep for the hospital called the newly engaged singer's procedure "successful," saying, "Michaels is currently recuperating at St. Joseph's where he remains for observation in ICU."
