An expert in aortic valve replacement surgeries, St. Louis University Hospital Cardiologist, Dr. Richard Lee, says the surgery is common. About 50,000 patients undergo the operation each year in the U.S. Dr. Lee, who did not treat Mike Shannon, says many patients receive a cow valve as a replacement. 95 percent of patients make it through the surgeries with no problems.
"I operated on a 90 year old just recently with the same surgery and she did unbelievably well. But, I'd say I would actually expect him to be better than he was before the operation. He's probably had some symptoms that were bothering him; that impaired his quality of life. Now that will be all gone."
Mike Shannon released a statement saying: "I would like to thank everyone for their prayers, heartfelt well-wishes and kind words. It means a lot to me. I'm looking forward to getting back in the booth and back to the game I love."
Shannon says he hopes to be back in the broadcast booth September 23rd. The Cardinals say they will rotate broadcasters to work with Cardinals announcer John Rooney as Shannon recovers.
