The office of Rep. Paul Kanjorski (D-Pa.) announced Monday night that the 12-term Congressman underwent heart bypass surgery at Brigham and Women’s Hospital in Boston. The operation to bypass blockages in three blood vessels surrounding his heart was routinely scheduled and was not the result of a heart attack, according to a statement released by Kanjorski’s office.

“Congressman Kanjorski is recovering well,” Lawrence Cohn, the Congressman’s surgeon, said in the statement. “There were no complications. We expect to keep him in the intensive care unit for the next day or so, and we have every expectation that he will recover fully and will have improved cardiac performance.”

According to the statement, the Congressman, who turns 70 on April 2, is expected to be hospitalized for about a week and should be able to return to work by the middle of next month.
