Question

Why had cardiac
surgery not developed?​

Answer 1

Answer:

Cardiopulmonary bypass was developed after surgeons realized the limitations of hypothermia in cardiac surgery: Complex intracardiac repairs take time, and the patient needs blood flow to the body (particularly to the brain), as well as heart and lung function.

Answer 2

Explanation:

Cardiac surgery has been described as a dying specialty with the astronomical growth of the field becoming overshadowed by its impending decline. The increasing use of less invasive methods is shifting the landscape away from open surgery toward the interventional techniques already dominated by other specialties. As with all good fiction, there is a foundation of fact. However this shift in practice signals not a slide into obsolescence but a new chapter in the history of a field still in its adolescence.
