Truth In Narrative
This is the story of how it came about that Minnesota played a major role in one of the most important medical developments in the 20th century. I am speaking about open heart surgery with emphasis on the word “open.” That word is usually glossed over as if all heart surgery is now and always was “open.”Actually, the first successful operation inside the human heart, under direct vision, was performed at the University of Minnesota on September 2, 1952. It was performed by F. John Lewis with Richard Varco assisting.Working inside the heart and being able to see directly what you are doing was a major problem: How do you keep the patient alive during the time when you stop the circulation long enough to get the job done? Lewis cooled the child to 28 degrees centigrade (82 degrees Fahrenheit) with refrigeration blankets. He interrupted the circulation for five and a half minutes, long enough to open the right atrium (right upper chamber of the heart), find and sew closed the atrial septal defect (a hole between the two upper collecting chambers that was causing life threatening problems, and then to close the opening he had to make to get inside the heart. The limiting factor with all of this was time. To close a simple atrial septal defect in less than ten minutes was not a problem for skilled hands using hypothermia but it was inadequate to protect the brain and other vital organs when more complex, more time consuming procedures were attempted. The purpose of this narrative is to give credit to the many sung and unsung heroes and heroines of Minnesota who helped make the dream of safe and unhurried open heart surgery come true.Besides the saving of millions of lives throughout the world, the ripple effect of what happened in the experimental laboratories and heart surgery operating rooms in Minneapolis and Rochester during the 1950s, 1960s, and 1970s has provided Minnesota with one of its leading industries: “Medical Alley,” one of the largest medical device industrial complexes in the world.
