Sen. Mike Duffy is recovering in an Ottawa hospital from open-heart surgery, the second such operation he’s had to clear up blocked arteries. Dr. Marc Ruel, chief of the cardiac unit at the University of Ottawa’s Heart Institute, conducted the procedure, which began at 6 a.m. Tuesday. Ruel treated the former broadcaster in 2006 for a similar heart problem. Duffy also suffered a minor heart attack in 1992. Andree Dumulon, a spokeswoman for the institute, relayed a message from Duffy’s wife Heather, saying, “the surgery went well and … he is now resting in recovery.”
