Episode 10 – John “Jack” Gibbon, M.D.

The Father of Extracorporeal Circulation

Born in Philadelphia in 1903, John Gibbon earned his medical degree in surgery at Harvard University in Massachusetts.

Early in his career, a defining event set the course of his destiny: during surgery to remove a massive clot from the lung of a patient who had developed a pulmonary embolism after gallbladder removal, he stood by helplessly as she died. Gibbon later declared that a device capable of diverting and oxygenating bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood outside the body might have saved her life.

A Visionary Idea

He then set out to design a pump capable of creating extracorporeal circulation, that is, a device that could simultaneously:

Oxygenate the bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood,
Prevent clot formation,
Protect red bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood cells from mechanical destruction.

These three conditions represented the major obstacles to be overcome before the machine could become functional.

A Family and Scientific Collaboration

For more than ten years, John Gibbon worked with his wife Marjorie, who shared both his laboratory and his efforts. World War II interrupted their research when Gibbon was called to serve as a surgeon in New Caledonia.

Upon his return, he resumed his project with the technical support of IBM engineers. Together, they succeeded in developing the first heart-lung machine that met the necessary safety standards.

The First Success

In May 1953, John Gibbon performed the first successful open-heart surgery using mechanical circulatory support. He corrected an atrial septal defect (ASD) in an 18-year-old patient, Martha Cowley.

The operation, lasting 26 minutes, went smoothly. The patient was discharged from the hospital a few days later: a world first that ushered cardiac surgery into a new era.

Painful Failures

The triumph was short-lived. The next two surgeries ended in the death of the patients. Shaken, IBM announced two years later that it was abandoning the project, citing a shift in priorities. Gibbon himself suspended his clinical work.

Carried Forward by Other Pioneers

Despite this halt, the principle of extracorporeal circulation was not abandoned. The Mayo Clinic and other centers picked up the work and refined the technique.

Progress was rapid: operative mortality, which was still 50% in 1955, fell to 25% in 1956, and to 10% in 1957. Today, depending on the type of surgery and the patient’s overall health, it is under 2%.

Legacy

John Gibbon died of a myocardial infarction in 1973 at the age of 69.

His legacy endures: nearly all modern cardiac surgeries use extracorporeal circulation (ECC). In medical jargon, it is still said that “the patient is on the pump.”
