Longtime Alice Cooper collaborator Dick Wagner is recovering after undergoing heart surgery.

The 71 year old guitarist, who wrote the power ballads I Might as Well Be on Mars and Only Women Bleed, checked into a hospital last week (ends11Jul14) after experiencing breathing difficulties.

He developed a lung infection after doctors cleared his arteries, according to Classic Rock magazine.

Wagner's son Robert tells the publication, "Prayers are welcome right about now. My dad is still in the hospital with a deep lung infection. Tomorrow they will wash his lungs. Doesn't sound fun, but I'm hoping it works and he can breathe again."

The rocker has been dogged by health woes in recent years - he previously suffered a heart attack and stroke, as well as kidney failure, and fell into a coma. His medical issues kept him from touring for over five years.

Wagner returned to the road with his Maestro of Rock Band in 2011.

As well as Cooper, the guitarist/songwriter has worked with Lou Reed and Kiss.
