RT Journal Article SR Electronic T1 Pioneering Alberta cardiac surgeons walked into uncharted territory 40 years ago JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 549 OP 551 VO 156 IS 4 A1 R. Cairney YR 1997 UL http://www.cmaj.ca/content/156/4/549.abstract AB When Dr. John Callaghan performed Canada's first successful open-heart surgery in Edmonton in 1956, the operation took 10 hours and the heart-lung pump he used looked like it had come from the shelves at Canadian Tire. Today the operation takes a couple of hours and the heart-lung pumps used cost $150,000. This article discusses Calaghan's pioneering work, which was recently honoured by University Hospital in Edmonton.
