Bret Michaels will undergo heart surgery at St. Joseph's Hospital in Phoenix, Arizona today to repair a hole in his heart, according to his rep.

"Barring any complications, I should be out within three to four days," Michaels told the Arizona Republic. "Then, I will be down for three weeks. I don't know if I can sit around for that long, but I'll try my best." Michaels' rep added, "Bret is looking forward to feeling 100 percent again."

Michaels was treated for a brain hemorrhage last April, and it was at that time that doctors discovered the hole in his heart. Michaels will undergo a cardiac catheterization where doctors will insert a catheter into a vein in his groin, guiding wires and a closure device into his heart with cameras. The closure device will remain in Michaels' heart permanently to stop abnormal blood flow between the two chambers of the heart, which is thought to have caused the stoke he suffered last year. Without the procedure, doctors say Michaels risks developing blood clots and an additional stroke.
