"Bret Michaels underwent a successful heart procedure today at St. Joseph's Hospital and Medical Center in Phoenix," the hospital said in a statement. "Michaels is currently recuperating at St. Joseph's where he remains for observation in ICU."
The hole in his heart was discovered last May, after Michaels, 47, suffered a mini-stroke.
That followed a series of scary health problems earlier last spring, beginning with an emergency appendectomy in April, followed soon after by a life-threatening brain hemorrhage.
Michaels, who got engaged to his longtime love Kristi Gibson in December, told PEOPLE last month that he was optimistic about the heart surgery.
"I gotta tell ya, I'm very positive," he said. "I feel positive they're going to do an amazing job. They've done thousands of these operations."
