At St Vincent's, Windsor created by 1950 a specialist department of thoracic surgery. With the help of his two protégés, Victor Chang and Mark Shanahan, Windsor was the Australian pioneer of cardiac valvular surgery in 1951; surgery employing hypothermia in 1954; cardiac valve replacement in 1963; coronary artery grafting in 1969, and, most notably Australias first heart transplant in 1968.
