Dr. Wilfred G. Bigelow, a Pioneer in Heart Surgery, Dies

Dr. Wilfred G. Bigelow, a cardiac surgeon who created a pathbreaking technique of cooling the body to allow open-heart surgery and also helped develop an early pacemaker, died Sunday in an extended-care facility in Toronto. He was 91. The cause was heart failure, his family said.
As a young surgeon at the University of Toronto in the 1940’s, Dr. Bigelow drew on his earlier research on hypothermia to theorize that cooling patients before an operation would curb the body’s demands for oxygen and slow its circulation, allowing for longer and safer access to the heart.
Dr. Bigelow successfully tested his theory on a dog in 1949 and announced the results at a meeting of the American Surgical Association in Colorado Springs in 1950. Three years later, the first successful surgery to use the cooling technique on a human was performed. In applying the technique, the patient was anesthetized and placed on a bed of ice to give surgeons a window of roughly 10 minutes of access to the heart.
The hypothermia technique was supplanted by the heart-lung machine in the 1960’s, although it is now used on parts of the heart during surgery in tandem with the machine to allow access to the heart for two or more hours.
